Two Radio links between two sites - one Triango microwave and the other Ubiquity PowerBridge M5 radio..
The Microwave needs to be used as a Primary link
The PowerBridge needs to be used as backup link.
They both connect using cat5 to 2960 switches on either side.
I need to configure the Cisco switches at either end for the radio link to auto failover onto the PowerBridge should the microwave link go down. And for the Microwave to regain primary status when it comes back online.
I need the switches to recognise when the radio has gone down and auto fail onto the Powerbrige rf link.
Can this be done with the 2960 Cisco switches and how?
Those methods would work IF when the radio link goes down the interface on the 2960 goes down as well. This is unlikely since the link going to the radio will still be active, but the wireless link from the local radio to distant radio will be down.
So spanning tree and flex links wouldn't know when the link went down because the interface is still up unless the radio itself goes down. Also, if both of these radio links are etherchannelled together, then spanning tree will treat them as one link and it wouldn't work because of that, as well.
I don't know if 2960s support IP SLA, but that's what I would use. You could setup up a track object to track reachability of an IP on the distant side sourced from that interface. In the event that it does, you could shut down the interface. Bringing it back up would be more difficult unless the local end of the radio link has an IP (like a gateway IP) you could track as its interface goes up/down.
If you were using a L3 switch or a router you could just put a routing protocol going and it would handle everything for you because even if the interface is up, the hello messages from the distant end won't be getting through. So, if you happen to have any of those available, that would be the better route to take.
Just some brainstorms since I am not
100% certain with these radios. I've only used some others, but for a L2 solution the local radio's "interface" having an IP you could track would be great. Otherwise, your hands are a little more tied.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
