Reseting Cisco 1841 Router
Please see the regular process to reset the password on 1841 Router below,
Connect the console cable to Router 1841
Use the power switch in order to turn off the router, and then turn the router back on
Press Break on the terminal keyboard within 60 seconds of power up in order to put the router into ROMMON
Type confreg 0x2142 at the rommon 1> prompt in order to boot from Flash
This step bypasses the startup configuration where the passwords are stored
Type reset at the rommon 2> prompt.
The router reboots, but ignores the saved configuration.
Type no after each setup question, or press Ctrl-C in order to skip the initial setup procedure.
Type enable at the Router> prompt.
You are in enable mode and should see the Router# prompt.
Type copy startup-config running-config in order to copy the nonvolatile RAM (NVRAM) into memory.
After this type "config-register 0x2102" as this will make sure after the next reboot to save settings.

Finding where computer is plugged into on a switch.
1. From a router or layer 3 switch...ping the ip address. 2. Do show arp | include "type ip address here" This will give you the mac address associated with the arp. 3. Do a show mac address-table | include "type mac address learned from 2." This will show you what vlan it is on and what trunk it used ie. gig 2/3 or gig 0/2. 4. Next you do a show cdp neighbor detail to learn ip address of next switch. 5. Repeat step 1. 6. Repeat step 2. 7. Repeat step 3. If mac address is on a trunk port....you have to do step 4 and go to next switch. If mac addess is on switchport....you have found port workstation is plugged into.
For 6509 instead of mac address-table use "show cam dynamic | include <macaddress>
