F5 not support cable failover? or how can be configure
Hi Pawan,
In your topology you should activate spanning-tree in the F5 box and play with priorities so that one of the F5 interfaces is always the one that's going to be blocking.
Note, however, that F5 does not support per-vlan spanning-tree - like Cisco switches use by default. Be careful with that.
If your switches are totally separate, I'd recommend trying MSTP. Most switch vendors support it and it's the only way to make everything 100% compatible.
If your switches are physically separate but support some sort of virtual multi-chassis link aggregation (Cisco VPC, Aruba VSF, etc.), or if they form a stack, you'd be better off using LACP. You'd eliminate loops and avoid spanning-tree issues.
