Ask an Expert How can I rename a virtual switch?

Answer:

Here is a way to rename a virtual switch:

Edit the file:
/etc/vmware/esx.conf

For example:

the original line:
/net/vswitch/child[0001]/name = "vSwitch1"

the renamed line:
/net/vswitch/child[0001]/name = "mySwitch_name"

After you have edited the file, reboot the ESX Server.

Note that you have to save the copy of your configuration to avoid risks. Also keep in mind that updates to esx.conf can wipe out the performed changes.
