how to unlink a NIC from a esxi vSwitch

 

List the vSwitches from ESXI using CLI:

        esxcli network vswitch standard list

 output example:

vSwitch0

   Name: vSwitch0

   Class: cswitch

   Num Ports: 1234

   Used Ports: 7

   Configured Ports: 128

   MTU: 1500

   CDP Status: listen

   Beacon Enabled: false

   Beacon Interval: 1

   Beacon Threshold: 3

   Beacon Required By:

   Uplinks: vmnic2, vmnic0

   Portgroups: VM Network,

Now remove the wrong NIC from the switch0:

esxcli network vswitch standard uplink remove --uplink-name=vmnic2 --vswitch-name=vSwitch0

To add the remove network NIC to vSwitch1:

esxcli  network vswitch standard uplink add --uplink-name=vmnic2 --vswitch-name=vSwitch1
