Folks,
This is my senerio.
Switch 1 has a port channel trunk of two fiber ports that are new and not 100% consistence.
Switch 1 used to have a trunk port that was connected to a wireless bridge before adding the fiber.
Is there a way to setup the copper trunk port as a backup connection to utilize if the fiber ports go down? Without creating a loop?
Thanks in advance.

Hi
if its layer 2 you can set the spanning-tree cost to 5000 on each end of the link that will make it a less preferred path at layer 2 and block it leaving the primary path open , cost allows you to manipulate stp so you chose where gets blocked and not leave it to the automatic feature

Ok I was having a little problems. Let me clarify the scenario...
Switch 1 has a port channel trunk of two fiber ports to Switch 2 that are new and not 100% consistence.
Switch 1 used to have a trunk port that was connected to a wireless bridge which was connected to Switch 3 before adding the fiber.
Is there a way to setup the copper trunk port as a backup connection to utilize if the fiber ports go down? Without creating a loop, even though the routes are different?
