Does for redundant LTM devices need to be configured with HA with gateway and vlan fail-safe mode to avoid service disruption?

We have deployed two LTM 5000 Load Balancers to load balance SIEBEL web traffic. Both are deployed in redundant mode and connected with upstream Cisco Nexus 5000 Switches in full mesh mode. When we t...

Sounds like you're using aggregated links / trunks from your description. If so then I'd recommend HA Group to monitor the health of the interfaces within this trunk. i.e. if an interface goes down then possibly failover.

 

I believe this is recommended over vlan fail-safe as it's quicker to failover (it's called Fast Failover). But for extra redundancy then vlan fail-safe is an option. Basically it checks that traffic is traversing this vlan (on a per vlan basis) and if not then it will initiate traffic before deeming that there is an issue (interface down) and failing over.

 

Hope this helps,
