HA for f5

Hi All,   For hardware 5250v do we have dedicated interface for config sync and connection mirroring? We are not using vcmp feature currently and will be using all 8 cpu for production traffic. ...

Thank Leonardo, this helps.a

 

So when we use rj45 as failover so this needs to be connected via crossover or straight cable directly?

 

Also since this interface doesn't show up in gui so we need to do any special config on cli or gui?

 

thank you for your help in advance.

I guess the comment from Shaun was referring to a normal interface, not the failover interface. The failover interface is not visible in the interface list neither via GUI or CLI, I also double check in 3600 unit.

 

The hardware failover only uses cable signal, there is no layer2/3 information, so no need to configure an IP.

 

You need a special cable, or just make one. As you can see in this solution, you need a crossover cable with pins 7 and 8 changed:

There is also this solution that talks about a better cable:

This solution explains network failover and hardware failover:
