The primary objective for the newly designed network is to minimize or prevent MAC layer attacks, Virtual LAN attacks, Spoofing attacks, securing network switches and configuring Virtual LAN across the network. For providing security mechanism to the internal data communication, Virtual local area networks (VLAN) are recommended. The VLAN separates the domain of the departments within the organization. VLAN uses encryption techniques for transmitting data over the network. Access policy list is also configured in the VLAN for defining the routes. Moreover, VLAN is considered as a broadcast domain. It concludes that the broadcast generates from one computer can only be received to the destination which is defined by some criteria in the broadcast domain. The advantage of VLAN implementation includes an efficient way of bandwidth utilization and eliminating the network from possible broadcast storms, which results in denial of service. Furthermore, by implementing VLANs, the capacity of switching technology is utilized to its full potential. VLAN also supports ‘VLAN trunking protocol’. The ‘VLAN trunking protocol’ will significantly reduce administration for the switched network. Addressing Security Issues and Deployment Approach for WAN A router is a core computing and packet processing devices in the Bigswitch computer network. Router connects two or more networks with different subnets, enabling the networks to expand on an enterprise level. Logically the router builds a routing table, where it stores all the route addresses. For example, the data packet source and destination is stored in the routing table. The network administrator can statically define the network addresses which are called as ‘static routes’. The dynamic routing protocol is used for the automation of exchanging data packets with other routers located in campuses of Bigswitch. The selection criterion of the router depends on the network requirements. The data transmission gauge, which is also called the maximum transmission unit (MTU), Read the full article

End-to-End and Local VLANs

There are two models in which you can design VLANs on a network: - End-to-End - Local   End-to-End End-to-End VLANs span across multiple switches within the network. Regardless of the user's physical location, they will consistently be assigned to the same VLAN. Consequently, the user's resources will belong to the same subnet. Management of end-to-end VLANs often involves utilizing VTP through trunked switches, facilitating streamlined management processes. However, reliance on VTP can sometimes lead to complications. Moreover, by extending the VLAN across the network, you enable broadcasts to traverse multiple switches. While this model may be suitable for small implementations, it may not scale effectively for larger environments. Local VLANs are confined to individual switches, typically organized according to geographic location. If a user relocates, they will be assigned to a different VLAN. Under the Local VLAN model, the local switch connects to a distribution or core switch, where routing takes place. Local VLANs exist solely between the local switch and the distribution or core switch. To communicate with other networks, traffic travels from the local VLAN to the distribution/core switch and is then routed to its destination. In this setup, VTP (VLAN Trunking Protocol) is not configured, and switches operate in VTP Transparent mode. Since VLANs are not broadcasted to other switches in the network, VTP becomes unnecessary. One advantage of this model is the elimination of extended layer 2 broadcast domains throughout the network. Troubleshooting is simplified compared to end-to-end VLANs, as traffic follows a defined path. In contrast, end-to-end VLAN traffic traverses multiple switches.   Read the full article

VLAN Trunking Protocol | VTP Domain Name

VLAN Trunking Protocol

VTP is the layer 2 protocol means the data link layer protocol. VTP is the cisco proprietary protocol and this protocol is the protocol that work is to carries the information of the VLAN to all the switches in the domain of VTP. VTP is protocol which is used to create, delete, and modify VLANs and then that propagates to the other switches in the domain of the VTP. So VTP advertisement can be done on the basis of the ISL trunks and 802.1Q.

VTP Prerequisite

Trunk is the prerequisite of the VTP.

VTP domain name should same on all switches.

There should be at least one server in the VTP domain.

If you enable the authentication than it should match.

VTP Modes

There are the three modes of the VTP that play different role in the VTP domain:

Server

Client

Transparent

Server

Server is the mode of the VTP which is used for the creation of the VLAN and this mode is also used for the deletion and the modification of the VLANs. If you create, delete, and modify any VLAN than it propagate to all the switches in the VTP domain. In this mode the configurations are all save in the start-up configuration that is also known as the non volatile random access memory (NVRAM).

Client

Client is the mode of the VTP which is not able for the creation of the VLAN and also not for the deletion and the modification of the VLANs. Clients mode's work is only propagate the configuration to other  switches.

Transparent

Transparent is the third mode of the VTP which is also used for the creation of the VLAN and this mode is also used for the deletion and the modification of the VLANs. So the roles of server and transparent are same but there is a big difference that is this mode does not participate in the VTP domain and because of this attitude of the transparent mode  it  used for the acquiring the privacy and security.

Standardized Configurations across the Network Replace with DeVry NETW206: Introduction to Switching Submitted Your professor’s nameDate: Current dateStandardized configurations across the networkA Virtual LANs otherwise known as a VLANs which are usually defined within switches, are broadcast domain that control broadcast, multicast, and unicast within a device in layer 2. They are placed on specific ports to restrict access. One VLAN cannot communicate with the other. For them to communicate, a router needs to be installed. A VLAN is important in that it addresses issues of security by restricting access to the sensitive information, it eliminates the need of purchasing additional expensive network equipment, and it also increase the performance of the network by supporting multiple broadcast domain, hence reduces the issues of traffic.The VLANs are going to be defined in our Cisco catalyst 4300-X series switch in the VLAN Trunking Protocal (VTP). After the creation of the VLANs, there is the creation of ports. The VLANs are created using numbers and the numbers are in two ranges for the creation, that is:1-1000 For the Normal Range1025-4096 For the Extended Range,To configure VLAN, the following steps are to be followed:Configuration of the VTP- VTP is a procedure that enables the Cisco switches to maintain the consistency of the database for the purpose of trunking. It facilitates easier administration of the VLANs.Then we create the VLANs- As stated earlier, VLANs are created using numbers. The extended VLANs are presently supported on the switches that run on the COS software edition 6.1 or greater.The creation of the solution template helps in the design of a standard modular network solutions. This solution template handles the issue of all non−standard, non device−specific configuration , for instance VLAN configuration, routing protocols, spanning tree parameters, among others (Lammle, 2011). For achieveing standard hostname, a naming system should be used, e.g the Network Information Systems, Domain Name System, among others. There are three privileges levels in a router:privilege level 1 which is for the non-privileged (prompt is router>), the default level for logging inprivilege level 15 which is for the privileged (prompt is router#), the level after going into enable modeprivilege level 0 which is seldom used, but includes 5 commands: disable, enable, exit, help, and logout. These privileges are assigned with the TACACS+ and the RADIUS servers.The Secure Shell otherwise known as SSH is a secure network protocol for the Cisco devices compared to telnet. Our Cisco switch can be setup to access the SSH by following the steps below:First we configure the hostname command,Configure the DNS domain,Generate the SSH key to be used,Enable SSH transport support for the virtual type terminal (vtys).Ideally, authentication protocols like the RADIUS, LDAP, TACACS+, among others provide a means to verify a legitimate user.

What is Cisco EtherChannel

EtherChannel may be a strategy utilized in Cisco switches to total transmission capacity from different switch ports. Another word for this method is bundling. On a Cisco switch you'll be able bundle two to eight ports. An example is the photo over. Two switch ports have been bundled together to put through to another switch. An illustration would be bundling eight quick ethernet ports. Each harbour is 100 Mbps. Increase 100 Mbps by eight and you get 800 Mbps. On the off chance that these were all full duplex ports you'd get 100 Mbps of bidirectional activity for each harbour totaling up to 1600 Mbps (8 x 200 Mbps) of amassed transmission capacity. In the event that these were gigabit ports you may get up to 16 Gbps (8 x 2 Gbps). When ports are put into the same EtherChannel they are considered bundled. To bundle ports, they must meet the taking after necessities: - Same Ethernet media - Same VLAN - Same duplex and speed If the bundle is going to be a trunk: - Bundled ports must be in a trunking mode - Same native VLAN - Pass the same set of VLANs - Same duplex and speed Benefits Aside from amassing transfer speed, another advantage with EtherChannel is excess. In case one of the ports within the bundle goes down, the other ports will need to choose up the slack. As a result you're utilizing EtherChannel, you're able to stack adjust the activity over different ports. Port Aggregation Protocols When configuring EtherChannel you have the choice of using two protocols: - Link Aggregation Control Protocol - Port Aggregation Protocol (PAgP) LACP is an alternative to PAgP and it is a standard (802.3ad). PAgP is a Cisco proprietary protocol. It isn't used much anymore.   Read the full article
