Steps to enable CDP on Standard Virtual Switch installed on an ESX server

To enable CDP on a standard virtual switch installed on an ESX Server:

1. Log in to the Service Console using SSH, remote console, or physical console as root. Verify the current CDP setting for the desired virtual switch. In this example, vSwitch1:

   [root@server root]# esxcfg-vswitch -b vSwitch1
   down
   

2. Set the CDP status for a given virtual switch. The possible values are:

   • down

     • listen

     • advertise

     • both

       [root@server root]#  esxcfg-vswitch -B both vSwitch1
       

3. Verify the new setting:

   [root@server root]# esxcfg-vswitch -b vSwitch1
   both
