I have two switches connected together (trunk connection)over fiber optic link. I install a point to point radio for backup to the fiber optic link but when the fiber link goes down I have to shut the port down and unshut the radio point. Is there any way I can enable auto failover for the ports?



I have the ff config on my switch.

interface FastEthernet0/20

switchport trunk encapsulation dot1q

switchport mode trunk

interface FastEthernet0/24

This should work automatically.One of the link will be blocked by STP. Check the " show spanning-tree details" on both the switches.
