Moving a vmnic from vDS to vSS at the host commandline

Occasionally when I’m proctoring my Test Track environment users will “accidentally” move vmnic0 on a host from the default vSwitch0 over to a Distributed switch.  As management traffic only runs across vSwitch0 I lose access to the host until I fix it from the command line.

I’m mostly posting this so I can quit looking up the command sequence each time.

Step 1:

Run

esxcli network vswitch dvs vmware list

and find the switch that vmnic0 was moved to.  Note the switch Name and Port ID.

one

Step 2:

Run

esxcfg-vswitch -Q vmnic -V dvPort_ID_of_vmnic dvSwitch

which drops the vmnic from the vDS

three

Step 3:

Now, add the nic back to vSwitch0 with:

esxcli network vswitch standard uplink add --uplink-name=vmnic --vswitch-name=vSwitch

    The first time I made this oops I used the console to reset the management networks. It undid the change but there weren’t any production distributed switches.

    Does beg the question – Will VMware ever support a vCenter cluster with all of the nics assigned to distributed switches?

    How to do the reverse, I mean move a vmnic from vSS to vDS ?
