The Number of BGP Neighbor Routing Entries Exceeds the Limit
Background: Two lines used by our company, one of which is the MPLS line of telecommunications, we need to pass the route to the BGP route of the telecom, and the BGP routing protocol of the telecom is transmitted to the corresponding routing table of the headquarters. Problem phenomenon: Suddenly the telecom MPLS line was broken, and then NETCARE called to report the failure. I thought the fiber was broken and let NETCARE arrange the hunt. After a while, the mail came over and said that the routing entries we posted exceeded the limit. Normally we can only publish a maximum of 20.
solution: I first connected to the company’s core switch to see the routing release. Show IP route EIGRP 1 I feel that there is no abnormal routing release. Show IP EIGRP nei Look at the establishment of the telecom EIGRP1 that is directly connected to me. The status is as follows:
*Apr 4 00:43:27.599 GMT: %DUAL-5-NBRCHANGE: EIGRP-IPv4 1: Neighbor 172.16.183.249 (GigabitEthernet1/0/1) is down: holding time expired BGP neighbor routing entries exceede
Clear IP EIGRP nei Re-establishing a neighbor, the result is useless. Because the console is on the router of the computer, there is also an EIGRP1 process running there.
At this time, I started to code people. The people who were looking for telecommunications, they logged into their own equipment, anyway, it was a check. There were not a few orders. Later, they found that their device and my core connected device port became half-duplex. They enter the interface Speed 100 Fuplex full
In fact, the phenomenon that gives people is that this line will be broken and will pass. Then just fine. So far, it is said that the number of BGP neighbor routing entries exceeds this limit. Dealing with this basic operator, the headache is their change process, you do not know who the configuration is, change and will not notify the customer, there is no way.

CCIE Security V5.0 Lab Exam Review
CCIE Security Lab Exam Description:
The Cisco CCIE Security Lab Exam is an eight-hour, hands-on exam, for which the candidates are going to require to plan, implement, design, operate, as well as troubleshoot complex security scenarios for a particular specification which were given to them. Knowledge of troubleshooting here would be considered as an important skill and candidates would be expected to diagnose as well as provide solution of certain issues as part of the CCIE Security lab exam. Though to clear the CCIE Security Lab Exam, isn’t going to be an easy task, but if you gain the premium materials provided by the SPOTO, they could really help you out in your preparation for the exam.
Lab Format
The eight-hour lab format consists of three modules and needs to be taken in the following sequence during the day of the exam:
Module 1: Troubleshooting module:
The Troubleshooting module is 2 hours. If desired, candidates can extend the Troubleshooting module’s time by borrowing up to 30 min from the Configuration module. Note, the total Configuration’s module time will be reduced by the extra time spend in the Troubleshooting module (if any, up to 30 min). If the exam takers would be able to finish the Troubleshooting module early, the unused Troubleshooting module’s time would be added to the Configuration module’s time, but they need to ensure that they don’t exceed a total lab exam time of 8 hours. The Diagnostic module is considered to be fixed in duration, which is 60 minutes.
Module 2: Diagnostic module:
The new Diagnostic module is going to focus on the skills which are going to be required to properly diagnose network issues, without having access to the device. Candidates would be provided with a set of documentation that would be representing a snapshot of a realistic situation: at a point in time in an investigation process that a network engineer might have to face. The main objective of the Diagnostic module is to assess the skills which are going to be required so as to diagnose properly network issues.
Module 3: Configuration module:
The Configuration module would be providing a setup very close to an authentic production network which would have various security components providing various layers of security at diverse points in the network. Though the major part of the module is going to be based on virtual instances of the Cisco security appliances, the candidate might be asked to work with physical devices as well. At the beginning of the module, the candidates are going to have full visibility of the entire module. A candidate would be able to choose to work in the sequence in which the items are going to be presented or you could resolve items in whatever order it seems preferable and logical to you.
Some Advantages of CCIE lab Exam:
High Salary:
The one who gets certified with CCIE certification could probably find a high-salary job. According to the Salary Comparison at PayScale, Salary Survey, Search Wages, an employee who is going to hold a CCIE Security certification can earn between $60,048 and $168,860 annually, which would depend on his/her experience. You would just have to spend a period of time to study hard, later on, you would be able to get a good job, with a high pay scale.
Promote to a higher office:
If you clear the CCIE, almost everyone would think you would have the superb ability in solving Network problems. It would provide proof about your ability and rich experience which you have on network solutions. Your boss would be able to trust you more and might push you into a good higher position.
So, if you wish to have all of these benefits, you could gain the CCIE Security Certification and for that, the best way would be to join the preparation courses offered by the SPOTO.

What Is the Difference Between CCIE RS and CCIE Security?
Well, CCIE Routers and Switching would be considered as an evergreen track. But at the same time, the importance that the CCIE Security track has, wouldn’t be denied as the value of it, is almost same as the value of CCIE R&S, which again would make it a bit complicated for the fresher to differentiate from.
After going through this whole article, you might be able to specify which course or track among the two would suit you best to him or her for their future specialization of CCIE. Before moving to the list of the facts, it would be good to make a thorough comparison of the outcome obtained with both of these tracks.
Career Scope of CCIE R&S and Security:
CCIE R&S:
It is a surprising fact to note that the industry demands for around 300,000 CCIE Routing and Switching certified professionals, whereas it has only 35000 active professionals as on date. This speaks about the untapped market and the huge skill shortage. As a layman, we all know that with the demand and supply imbalance, where demand is higher than the supply, we have the opportunity to encash it for high packages for respectable positions in the networking domain.
CCIE Security:
The challenging era of digitization and internetworks, there is a strong demand for expert IT infrastructure professionals who can design, administer and maintain secured networks ensuring smooth functioning throughout the enterprise environment. According to the stats, there are only 6000 security professionals while the demand is nearly around 200000 which is an amazing opportunity to have a secured career with a great future.
Expected Job Roles and Growth opportunities
CCIE Routing and Switching:
After completing CCIE Routing and Switching, you get eligible for promising career profiles of:
• Network Engineer
• Senior Network Engineer
• Network Administrator
• IT Manager
• Network Specialist
• Principal Network Architect
Not only reputed designations, but CCIE Routing and Switching track can fetch you a handsome starting package of minimum $94,582 per annum.
CCIE Security:
CCIE Security certification opens doors to multiple profiles in the Networking domain depending on their skill sets. Let’s have a look at the Job Opportunities that you would have after CCIE Security:
• Network Security Administrator
• Network Security Engineer
• Senior Network Engineer
• Security Analyst
• Network Security Engineer
• Network Security Specialist
A CCIE Security certified fresher can expect a minimum salary of $101,039 per annum at the very beginning of their career.
CCIE Certification Road Map
For CCIE Routing and Switching, your learning starts with:
• CCNA Routing and Switching
• CCNP Routing and Switching
• CCIE Routing and Switching
The CCIE Security certification journey is designed to up-skill your understanding and internetwork expertise. To achieve this level you start from here:
• CCNA R&S (Associate)
• CCNP R&S (Professional)
• CCNA (Security Associate)
• CCNP (Security Professional)
• CCIE Security (Expert)
Note: It is a mandatory pre-requisite to have Routing and Switching knowledge for pursuing Cisco Security track.
If Networks fascinate you and you wish to master them, then CCIE is the best choice to make. Going by the opportunities and the pay scales, CCIE security supersedes the Routing and Switching track, but not to forget, CCIE security stands unachievable without an in-depth understanding of Routing and Switching.
So, whichever Certification, you like to go with, trust me; you are going to need lots and lots of studying and training to gain them. It would be thus recommended for you to gain the training which you could obtain through the well-reputed and reliable training providers like the SPOTO. When it comes to Cisco Certification and much more, SPOTO would be the best training provider for it.

Breaking News: New Changes to the Cisco Certification Programs.
In June 10, 2019, Cisco posted their official announcement on the upcoming changes for their new Cisco Certifications. So, how does it change in details?
The Next-level Cisco certifications:
SPOTO will introduce the details of New CCNA, CCNP, CCIE and CCIE lab exam format. If you have more questions, you can also contact us now.
Changes in CCNA:
The original 9 tracks of CCNA merged into one, the united exam code is 200-301.
Changes in CCNP:
The original CCNP R&S and CCNP Wireless will be merged into one track-- CCNP Enterprise.
The CCNP exam format change, originally required 3-5 written tests to pass. But the new generation of CCNP certification can only be obtained through 2 exams, that is one compulsory exam, plus one optional exam.
Candidates can attend the CCNP exam directly, without having CCNA certification.
Changes in CCIE:
The CCIE R&S is changed to Enterprise Infrastructure, and the existing CCIE RS certification will be automatically upgraded to Enterprise Infrastructure certification after the new certification is released.
CCDE is changed to DevNet, CCDA is changed to DevNet Associate, CCDP is changed to DevNet Professional.

A Significant Update of Cisco’s Professional Certification Program.
Evolution of Cisco’s professional certification program involves both the network professional and now the software developer into one community to create the IT team of the future. SPOTO will give you the latest news and ensure you can know some evolution of CISCO’s certification. What’s more, the evolution will take an effect on 24 February 2020, which means that you have better take the exam soon before the evolution. On February 24, 2020, Cisco will release a new certification and training program. The last day to test under the current certification program is February 23, 2020.
The new Cisco Certifications include:
New DevNet Certifications to validate software professionals with DevNet Associate, DevNet Specialist, and DevNet Professional certifications. DevNet certifications are intended for software developers and network engineers who develop software proficiency to develop applications and automated workflows for operational networks and infrastructure.
Streamlined Cisco Certifications to validate engineering professionals with Cisco Certified Network Associate (CCNA®) and Cisco Specialist certifications as well as Cisco Certified Network Professional (CCNP®) and Cisco Certified Internetwork Expert (CCIE®) certifications in enterprise, data center, service provider, security, and collaboration.
Expansion of Cisco Networking Academy offerings to train entry-level network professionals and software developers. Courses prepare students to earn Cisco Certified Network Associate (CCNA®) and Certified DevNet Associate certifications, equipping them for high demand jobs in the IT industry.
The changes in CCIE Certification
CCIE Certification now involves Enterprise Infrastructure, Enterprise Wireless, Collaboration, Data Center, Security, Service Provider. The CCIE RS certification is replaced with Enterprise Infrastructure, and CCIE Wireless certification replaced with enterprise wireless. Their codes are the same, namely ENCOR 300-401. The others are not changed, but their codes have a huge change. The codes of CCIE Collaboration, Data Center, Security, and Service provider separately are CLCOR 300-801, DCCOR 300-601, SCOR 300-701, SPCOR 300-501. Moreover, the CCIE Lab exam consists of two modules. Module1 includes Design with fixed 3 hours, which is similar to the DIAG and no equipment. Module2 involves Deploy, operate and optimize with fixed 5 hours. If you want to become a CCIE, you have more chances to choose the exam that you consider you can be good at.
The following is the details about changes of CCIE:
The Changes in CCNP Certification
The evolution of CCNP Certification exam involves enterprise, collaboration, Data Center, Security, Service provide. They are named the compulsory exam. Their codes are 300-401 ENCOR, 300-801 CLCOR, 300-601 DCCOR, 300-701 SCOR, 300-501 SPCOR. CCNP RS and CCNP Wireless are replaced with CCNP Enterprise Certification. Moreover, CCDP certification is changed with the DevNet Professional. The best benefits are that you have more opportunities to choose the optional exam, but you must take at least one exam. I want to take an example that can help you understand the exam rules. If you want to take CCNP Collaboration Certification, you must take the 300-801 CLCOR and pass the compulsory exam. Then, you can choose an optional exam that you consider it is easy to clear. Besides, if you want to become CCIE after passing the compulsory exam CCNP Collaboration exam, you only need to take the CCIE Lab exam and pass the lab exam. After that, you will be a CCIE, which makes the exam easier with less money. There are no formal prerequisites for CCNP/CCIE, but you should have a thorough understanding of the exam topics before taking the exam.
The following is the details about changes of CCNP:
The Changes in CCNA Certification
Only one kind of CCNA certification that you should take and its code is CCNA 200-301. The CCNA Wireless is replaced with the DevNet CCNA.
The details are followed:
Now 24, February 2020
Starting February 24, 2020, all certification levels will have a three-year recertification requirement. Certified individuals will be able to recertify by completing continuing education activities, taking exams, or a combination of both.
SPOTO will update timely the latest news about the evolution of CISCO certification. Don’t hesitate to follow us and you will not miss any news.

Is the CCIE Certification Worth Pursuing For the Future's Market?
This question about whether the CCIE certification is considered to be worthy or not, it has been swirling for years with no clear answer. CCIE commands a high salary, but so do many certifications. When it comes to reputation, nothing compares. It is an individual decision that you would have to make before devoting money and time to the certification.
Why CCIE is worth it?
For starters, any certification signals that would have skill and dedication to an employer. The CCIE is going to bring immeasurable bona fides to your resume because it is considered to be the pinnacle of your certification pathway. Thought of as the PhD-level certification, the CCIE is going to comes with a lot of cloud among peers and employers. As for cost, it is considered to be an expensive exam, costing about more than $2,000 for both the written and labs portion of the exam.
And you would be finding opportunities. We have heard from lots of trainers that you could get a lot of attention from recruiters for high-level job opportunities. There are lots of training providers, which helps the candidates by providing them good training courses, like that offered by SPOTO.
There are six types of CCIE which would be offered by Cisco namely security, service provider, wireless, data center, collaboration, and routing and switching. These certifications are expert, high-level qualifications that would make you stand out from the crowd, which would be giving you the opportunities to grow and advance your career as a Cisco Network Engineer. Anyone of these certifications would highlight your intimate knowledge of Cisco Systems in the allotted domain in which each one is going to be based, making this CCIE certification is considered to be highly desirable.
It is worth pointing out that there is one final tier above CCIE Routing & Switching. The holy grail of networking, the CCAr (Cisco Certified Architect) would be required to be a mere $15,000 to take and entails an in-person board examination where you are going to defend a network architecture you would be designed.
Is it still worth pursuing the CCIE?
Basically, the answer would be depending on the knowledge and mindset of the candidate. So, if you wish to gain the answer to this question, you would have to ask yourself. No doubt the CCIE is considered to be the highest level of certification provided by the Cisco, and you would achieve lots and lots of benefits by being certified as a CCIE. But you should consider that for achieving the CCIE Certification, you would have to go through lots and lots of training, so if you are ready for that, it is totally worth pursuing you.
Conclusion:
The CCIE would have to add you up to your employment prospects, and to your earning potential. While there are many other certifications that would increase your salary, those would be irrelevant to your career path. If you are going to be interacting with Cisco devices, then no other certification would stand up to the CCIE after your name. Although many of the concepts that you would be learning in the CCIE are universal, your real value is going to be realized in a Cisco shop.
This is a choice which you and only you could make for yourself. If you decide to pursue it, then I would like to recommend you to join the training courses, which are provided by SPOTO, it would help you out to achieve your certification, with as much less effort as possible. So, join SPOTO and grab your dream of achieving this certification.

BGP AS Path Attributes.
BGP Attributes
BGP Attributes catch more attention in the IT industry, and SPOTO is committed to BGP Attributes. What’s more, SPOTO involves so many certifications as CCIE RS, CCNA, CCNP, and CISSP certification. If you want to get more information and download some free study materials, and you can contact us. BGP support a wide variety of path attribute, BGP chooses a route to a network based on the attributes of its path.
Four categories of attributes exist are as follows:-
Well-known mandatory
Well-known discretionary
Optional transitive
Optional non-transitive
A well-known mandatory attribute must be recognized by all BGP routers, present in all BGP updates, and passed on to other BGP routers. AS path, origin, and next hop.
Well-known discretionary must be recognized by all BGP routers and passed on to other BGP routers but need not be present in an update. Local preference.
Optional transitive might or might not be recognized by a BGP router but is passed on to other BGP routers.
If not recognized, it is marked as partial. Aggregation, community.
Optional non-transitive If the BGP process does not recognize the attribute then it can ignore the update and not advertise the path to its peer. Multi-exit discriminator (MED), originator ID
AS_Path attribute- this particular path attribute lists the autonomous system numbers in the end-to-end path.BGP uses AS_Path as its primary loop-prevention tool.
AS_Path attribute is a well-known mandatory attribute. its list of AS through which updates are coming. The shortest AS_PATH list is more desirable.
Next_hop is a well-known, mandatory attribute next hop means IP address to reach the next autonomous system because BGP is AS by AS routing protocol.
Origin attribute origin informs all AS in internetwork how network got introduced into BGP.
(i) represent IGP
(e) represent EBGP
(?) represent incomplete
Weight Attribute is a cisco's attribute. its tell how to exit the AS, a path with the highest weight is more desirable. weight is a partial attribute, by default weight 0 learn route 32,769 for locally injected routes. its local to the router did not advertise to any BGP peers.
Local Preference Attribute
Local preference defines how to data traffic should exit from an Autonomous system. path with the highest preference value is more desirable by default is 100, and the range 0 through 232 local preference is well known, discretionary attribute it is advertised only to iBGP neighbor within an Autonomous system.

Internetworks: BGP Confederations and configuration.
BGP Confederations
We’ll exchange the BGP Confederation with you in this section. You might know, IBGP requires a comprehensive mesh peering which can become administrative overhead. If you don’t know why we need a comprehensive mesh, I advise consulting BGP peers first. Over the past 16 years, SPOTO is a leader in the IT training, and you can get various exam materials to help you clear all certification exam. Let’s look at the following contents now.
IBGP full mesh issues
·As for iBGP, every router in the BGP autonomous system must fully mesh.
·Large number of TCP sessions
·Unnecessary duplicate of routing traffic
·Manual configuration
Solution
1.Route reflector
2.BGP confederations
A BGP confederation consists of AS and sub-ASes to reduce the number of required IBGP peerings. In brief, BGP Confederations Feature is used to divide an autonomous system into smaller autonomous systems.
Confederations are usable only for huge autonomous systems where you can afford to divide them into several sub-ASes. Each sub-as in a confederation is required to have its internal iBGP peers either fully meshed or use route reflector internally. The confederations are not much of an advantage for small ASes having a few BGP routers.
let's see the configuration for better understanding.
Topology:
Goal:
·configure the topology as per the diagram and assign the IP addresses.
·configure iBGP and EBGP configuration.
·configure BGP peerings using BGP Confederations.

Advantages to Join the CISSP Certification Exam Training.
CISSP stands for the Certified Information Systems Security Professional, which is considered as the certification program in the field of Information Security. The certification is devised as well as presented by a global non-profit organization, International Information Systems Security Certification Consortium ((ISC)²), which is specialized in the field of IT security. Often termed as the world’s largest IT Security organization, (ISC)² would be maintained a Common Body of Knowledge for the domain, and that would be offered various security certifications, that would be including CISSP, CSSLP, and CAP.
CISSP Exam Requirements
The requirements that are needed in order to take the CISSP exam that wouldn’t numerous, but they are considered to be a fairly strict, clear cut, as well as take into account that would be considered as your experience as an information security professional.
Each candidate should have a minimum experience of five years of working full-time in at least two or more than two of the eight CISSP domains, which would be dictated by the (ISC)² CBK. These eight domains are Information Security Governance Access Control, Telecommunications, and Network Security, and Risk Management, Software Development Security, Security Architecture and Design, Cryptography, Operations Security, Business Continuity and Disaster Recovery Legal, Planning, Regulations, Investigations and Compliance, and Physical (Environmental) Security. Acquiring this certification would be quite a chaotic task, but if you have a good CISSP training provider, like the SPOTO.
CISSP candidates might also be able in order to receive a one-year experience waiver, as long as the candidate who has acquired four-year college degree or an additional credential from the approved list of credentials of the (ISC)². Each of these approved credentials would still require four years of full-time professional experience with at least two of the eight CISSP domains which were listed previously.
Benefits of CISSP Certification:
There are a good number of benefits of the CISSP certification for both professionals who are working in the information security field as well as for the employers. Let's us discuss and examine some of them which are mentioned below.
As the CISSP exam is considered to be a widely-accredited assessment of your knowledge, skills, and experience in the information security field, it is no doubt an incredibly important credential in order to have on your record.
Here are three major benefits of becoming CISSP certified as a professional:
• Becoming CISSP certified means that you would have an extensive working knowledge of about how information security would be working. This means that you should make yourself that would be very valuable to professional technology organizations.
• Becoming certified automatically would be enhancing your professional credibility as well as the ability to market yourself in order to a wide range of different technological companies.
• You would be receiving exclusive benefits as an (ISC)² member, which would be including the professional networking and idea-exchanging opportunities.
Companies which are there in the tech industry would have difficulty maintaining the security of their organization's critical information all by themselves. That is considered why you would be having a certified CISSP on their side is very important.
Here are three benefits of becoming CISSP certified from the perspective of an employer:
• Hiring somebody who is accredited with the CISSP certification instantly would provide an increase in their credibility and the value of your company on a global scale.
• Having a certified CISSP on your team would be validating your organization's years of commitment and experience to the IT security industry.
• Working with a CISSP professional would be satisfying certain certification that would mandate that is required of many clients as well as subcontractors.
So, if you wish to have the CISSP certification, you could have it through the training which you could gain at the SPOTO.

My First Attempt in Passing the CCIE Lab Exam.
I have passed my CCIE Lab exam at the first try with the help of SPOTO on 4, May 2019. I will give you some advice to prepare your exam.
1. Based on your learning direction, prepare the corresponding experimental equipment. Choose to build your own lab or use the equipment in the training center. Because the experimental equipment is quite expensive, most of the domestic candidates use the equipment of the training company. More recommended Shanghai SPOTO, 24-hour laboratory free to open to the college.
2. Prepare the required books and learning materials and familiarize yourself with the way to access Cisco online technical documentation. Because this is the only technical material you can refer to during the exam, it is also a must-have skill for Cisco technical experts, saving valuable exam time.
For every knowledge point, you need to know what it is, and you know why.
3. For each requirement in the exam, read and understand it carefully, and don't let go of every modifier. If you encounter a word you don't know, you can ask the examiner for help to ensure a complete understanding of the problem. When you have completed the configuration of a requirement, test and troubleshoot immediately. Avoid affecting others due to configuration errors of this feature.
4. Remember the port number used by commonly used network protocols. Based on the OSI model, the development of structured troubleshooting habits, according to the wrong appearance, can be started from the bottom, but also from the top.
Second, CCIE lab exam FAQ
When you are ready for the exam, remember: "Relax, maintain a healthy mind." In addition to this, here are some technical issues to be aware of:
1. If the task you are trying to accomplish needs to reference your previous configuration, whether you use ‘name’ or 'number’, make sure you match it.
2. Ensure that the meanings and calculation methods of the TIMERS and METRIC values involved in various routing protocols are accurately understood and how they are configured. The actual situation of the network should be matched as much as possible according to specific requirements.
3. Don't try to get hints or answers from the examiner at any time. There are uncertain words in the question to ask the examiner. The examiner will tell you the original meaning of the English. You need to understand the impact of a specific word on the technical requirements, such as ‘MUST’, ‘MAKE SURE’, and so on.
4. Some functions need to refer to the parameter 'absolute value' or 'incremental value'. They are two different concepts. Do not confuse according to specific requirements.
5, to complete a demand, sometimes there are several programs, we must carefully read and understand the requirements of the topic. Some keywords will give you hints, such as ‘CAN NOT’, ‘AVOID’, and so on.
6. After the lab exam begins, you must carefully read the precautions and requirements of the exam and the exam description. It contains a lot of very important information. Don't take it for granted. You must ask the examiner if you don't understand the problem.
7. Read the questions from beginning to end before answering the questions. Do as much as possible in the order of the questions. If there are any problems, skip it and do the next question. It is very likely that you will find the problem you just skipped. You know how to answer it.
8. Develop a good habit of making records. When you read through the topic, record the “key points” and “keywords” that you think are important on the draft paper. Don’t miss the “critical requirements” in the later configuration. ".
9. Manage limited exam time. After reading the exam questions, the number of questions you already know, the time required to properly assign each question, must not spend too much time on a small problem.
10, must know how to check the functions you have configured, Cisco provides a wealth of functional check commands, must pay attention to accumulation in the usual study, as many as possible to verify when the exam, to ensure that you configure the function accurately.

LAN Switch Overview And Maintenance Instructions.
SPOTO focus on IT certification training for 16 years. We always offer the latest tips and valuable study materials for every engineer. Subscribe us and get more news.
The store-and-forward mode is the most widely used method in the field of computer networks. It stores the data packets of the input port first and then performs CRC check. After processing the error packet, the destination address of the data packet is taken out and converted into an output port through a lookup table. Send the package.
For this reason, the store-and-forward method has a large delay in the data processing. This is its shortcoming. It can detect errors in packets entering the LAN switch. It is especially important that it can support input and output ports of different speeds. The conversion keeps the high-speed port and the low-speed port working together.
Layer 2 and Layer 3 switching and their competition with router solutions
The LAN switch works on the second layer of OSI and can be understood as a multi-port bridge. Therefore, it is traditionally called Layer 2 switching. Currently, switching technology has been extended to some functions of the third layer of OSI, the so-called third layer. Exchange, the third layer exchange cannot spread the broadcast packet, directly use the dynamically established MAC address to communicate, it seems to be able to understand the third layer of information, such as IP address, ARP, etc., with multi-channel broadcast and virtual network based on IP The routing function of the protocol such as IPX, the smooth implementation of this function is due to the addition of the application-specific integrated circuit (ASIC), and the traditional software-processed instructions are changed to the embedded instructions of the ASIC chip, thereby accelerating the forwarding of the packet and Filtering ensures reliable linear routing and quality of service at high speeds. At present, if there is no need for a wide area network, routers with expensive and limited bandwidth are generally not used in the network construction scheme.
Virtual local area network technology
The development of switching technology allows a geographically dispersed organization to logically become a new working group, and members of the same working group can change their physical addresses without having to reconfigure the nodes, which is the so-called Virtual Local Area Network (VLAN). To establish a virtual network with a LAN switch is to divide the original large broadcast area (all ports of the switch) into several "sub-broadcast areas". The broadcast packets in the sub-broadcast area will only be transmitted in the broadcast area. The broadcast area is not available. VLANs effectively separate traffic by switching technology to better utilize bandwidth and logically partition the actual LAN infrastructure into multiple subnets, allowing different LANs to run different application protocols and topologies. Readers interested in this part of the details can refer to the IEEE802.10 regulations.
LAN switch maintenance
Introduction to LAN Switch <> Introduction to Catalyst6000 Series <> Introduction to Catalyst5000 Series <> Basic Maintenance Commands for Catalyst 6000 Series and Catalyst 5000 Series.
Overview of LAN switches
LAN switches have evolved from a traditionally shared HUB-type LAN to a broader space. Take Cisco's Catalyst 5000 series LAN switch as an example. It includes an integrated switching hardware structure that supports switched 10-Mbps Ethernet and 100-Mbps Fast Ethernet through Fast Ethernet, FDDI, and switched Token Ring. Exchange processing power with Layer 3. This type of switch provides switched access to workstations, servers, network segments, backbone networks, or other users within the LAN.
Cisco IOS Software provides advanced network services for the Catalyst platform and web applications. Cisco IOS technology is optimized for switching and can be used with all Catalyst switches, including FastEtherChannel technology for bandwidth aggregation; Cisco Group Management Protocol support for optimized multicast and multimedia traffic performance; and extensive management features. Cisco IOS Software also supports virtual local area network (VLAN) configuration and management, IP address management, and secure network service access.
Introduction to the Catalyst 6000 Series
The Catalyst 6000 family includes the Catalyst 6500 Series and the Catalyst 6000 Series, providing a new range of high-performance multilayer switching solutions for campus networks. Designed to meet the growing demand for gigabit scalability, high availability, and multi-layer switching in a backbone/distribution and server aggregation environment, the Catalyst6000 family delivers superior scalability and price/performance, supporting a wide range of interface densities, performance, and high Availability options. By providing application intelligence, quality of service mechanisms, and security, customers can more effectively leverage their networks to add customer services (such as multicast and ERP applications) without sacrificing network performance. When combined with Cisco IOS' extensive network services, the Catalyst 6000 family delivers the powerful management, user mobility, security, high availability and multimedia support required for enterprise intranets.
Introduction to the Catalyst 5000 Series
In addition to the Catalyst 5000, Cisco's Catalyst 5000 series switches include the Catalyst 5002, Catalyst 5500, Catalyst 5505, and Catalyst 5509, all of which are enhanced by the Catalyst 5000. The old equipment in this project is a Catalyst 5509 switch. Taking the usual Catalyst 5509 as an example, the Catalyst 5509 rack has 9 slots. The first slot is used for the supervisor engine module. This module provides Layer 2 switching and remote network management. The module has dual-port, full-duplex fast Ethernet. Network interface. You can connect to other Catalyst5000s, routers, and servers at the highest rate of 400Mbps; the second slot is the supervisor engine module for plugging in backups. The other seven slots can be used to combine any switch module and Route Switch Module (RSM). The Catalyst 5509 chassis fit into a standard 19-inch rack. All system components can be operated on the same side of the chassis. A complete system must be configured with a power supply. For fault tolerance, dual backup, load balancing, and power pluggable power supplies are available.
Basic maintenance of Catalyst 6000 series and Catalyst 5000 series
The Catalyst 6000 Series and Catalyst 5000 Series LAN Switches are powerful, including many usage and maintenance commands. Below, list a few commonly used commands and a brief description. Please refer to the relevant manual provided with the hardware device for all relevant maintenance commands.

CCIE Security Practice Labs PDF.
Before we discuss the CCIE Security Practice Labs, let’s first have a brief overview of the CCIE Security Lab Examination.
CCIE Security Lab Exam Overview:
The Cisco CCIE Security Lab Exam is considered to be an eight-hour gruesome and hands-on exam that is going to be required a candidate for planning, designing, implementing, operating, and troubleshooting various complex security scenarios for a given specification. Knowledge of troubleshooting also would be considered as an important skill and candidates that are expected for diagnosing and solving issues as part of the CCIE Security lab exam. CCIE Security Exam would be considered to be one of the most demanded certifications and to gain it, you should have some intense training. You should gain it by gaining the courses which are offered by the SPOTO.
The format of the CCIE Security Lab Exam:
The eight-hour lab format is going to be consisting of three modules and would need to be taken in the sequences which are followed during the day of the exam:
Module 1: Troubleshooting module:
The Troubleshooting module would deliver incidents that are considered to be independent of each other, which means that the resolution of one incident wouldn’t be going to be dependent on the resolution of another. The topology that is utilized in the Troubleshooting module is different than the topologies which were utilized in the Configuration module.
Module 2: Diagnostic module
The new Diagnostic module would be focusing on the skills which would be required to properly diagnose network issues, without having device access. Candidates would be provided with a set of documentation that is going to be represented a snapshot of a realistic situation: at a point in time in an investigation process that a network engineer might have faced. The main objective of the Diagnostic module is to assess the skills which would be required to properly diagnose network issues.
Module 3: Configuration module:
The Configuration module is going to provide a setup which seems to be very close to an actual production network which would be having various security components providing various layers of security at dissimilar points in the network. Though the major part of the module would be based on virtual instances of the Cisco security appliances, the candidate might be asked to work with physical devices as well. At the beginning of the module, the candidate would be having full visibility of the entire module. A candidate could choose to work in the sequence in which the items are presented or they could resolve items in whatever order in which they seem preferable and logical.
CCIE Security Practice Labs:
The material which would be covered in CCIE Security v4.0 Practice Labs is designed in order to help the candidates for preparing for the CCIE Security exam by providing a complex topology and two practice labs which would be enforceable problem solving, troubleshooting, and policy design were using topics and equipment that would be detailed in the official exam documents.
Each solution is going to be explained in detail in order to help out for reinforcing. It would be presenting other deployment options or enhancements and provide additional practical implementation tips. Initial and Final configuration would be cut and pasted onto lab devices so as to further testing and verification are also included.
These labs would be serving as a practice tool for prospective CCIE Security exam candidates and, through the use of real-world lab topologies and in-depth solutions and technical notes, would be also a useful reference for any security professional involved with practical customer deployments that would be using Cisco products and solutions.
CCIE Security Exam would be quite difficult to achieve unless, you gain the expert training which would be provided by the courses, which are available online, like that is offered by the SPOTO.
