Network failover interface
This seems like a really simple problem, I'm just not sure the right way to go about it in 11.1.
This morning, a tech accidentally unplugged one of two switches I have behind my F5. When he did that, my F5 lost access to all its nodes. Here's why:
My 11.1 F5 is configured to have one interface for the OUTER and one interface for the INNER VLAN traffic. The inner traffic was plugged into the switch that was powered down.
Now, my second F5 is in Active/Passive config and is configured the same way, except its INNER is plugged into the other switch that wasn't powered off.
So, had I manually failed over my F5 to the other device I would've been fine.
My question is, isn't there a way that I can use one of my other unused interfaces to connect to an alternate switch and have it used when the 'primary' interface loses connectivity? Interface mirroring seems wrong because I don't want my traffic going out both interfaces.
Is it as simple as assigning both interfaces to my VLAN? And then does the F5 use only the first in the list unless....
