Should I configure the VLAN Failsafe failover only in the active unit? Or the best practice is to configure it on both active and standby units? I'm running version 10.2.you can configure vlan failsafe on both units but just want to make sure they are not triggered at the same time.
anyway, if you want to just failover when interface on bigip is down, i think ha-group might be better solution.
