This is my scenario, I have wan connection with three vlan, one by Optical fiber and another one is by Radio link as backup. I connected fiber link to sfp1g port and radio link to ether 1. Now i want to setup fail over in which while my fiber link is up my radio link port ether 1 will be obsolete if fiber link goes down it will automatically switch over to ether 1 radio link and when fiber link at sfp 1g port comes again eadio link of ether 1 will be obsolete, how can i do this?
Are both links terminating in the same L2 domain?
If so, make sure your ISP is running RSTP and allows you to connect to their RSTP domain - and let them tell you which bridge priority to use.
Move SFP1 and ether1 to a bridge running RSTP and configure it to the given priority.
Increase path cost of ether1 in /bridge ports to a higher value than sfp1.
That should be it.

Well as you suggested in that case i won’t get any help from my isp cause their eng. is against any type of bridge interface and says it will create loop etc etc i was thinking of bonding active backup any help with bonding active backup mode please as far i know 98% percent hardware used to my route is BDCOM 10g and Cisco SF300 switches
Now that will really get complicated.
I could imagine a bridge interface, both feeds connected to it with the same bridge horizon and some scripting.
If the main link goes down, first disable the wired port, then enable the w/l port.
Then manually fire a script when the wired port comes back up, first disable the w/l port, then enable the wired port.
Not really nice. :-/
And I would not act against your ISP’s engineers advice.

My current setup is that as you said just manually trigger port on and off. Anyone else have any solution ???
