How to change the NIC assiociation in ESX 3.5

To change the NIC assiociation, the existing NIC must be unlinked by typing the following command at the service console:

       esxcfg-vswitch -U vmnic# vSwitch#

In this example, say we want to unlink the NIC vmnic0 from vswitch0, so in this example the appropriate command would be:

      esxcfg-vswitch -U vmnic0 vswitch0

Use the following below command to assiociate a new NIC with the vSwitch:

        esxcfg-vswitch -L vmnic# vSwitch#

For Example, if you want to assiociate vmnic1 with vswitch0 then the appropriate command would be:

        esxcfg-vswitch vmnic1 vswitch0
