A little while back, I wrote on Changing your vSwitch Names on ESXi Host. I found another way to do this, but unfortunately, this method ONLY works for NEW vSwitches.
Once the vSwitch has been created, you cannot change the name to something else. If you made a mistake and need to change it, you would need to either:
a. Removing the vSwitch and recreating it
b. Doing the Changing your vSwitch Names on ESXi Host option.
- Select Networking
- Select the Virtual swiches tab
- Click Add standard virtual switch
