How to Get Cisco (CDP) Data on the Command Line.

Troubleshooting networking is rather difficult if you can only connect to your ESX box via the console. Luckily I came across the instructions below

To extract CDP information using the ESX command line:
  1. Log in into ESX 3.5 via SSH as root.
  2. Run the following command on ESX command line :

    > vmware-vim-cmd hostsvc/net/query_networkhint

  3. The following information is displayed:
  • Virtual switch port information
  • CDP information from the physical Cisco switch connecting to the ESX host .
