Active/Passive pair on LTM and ARP updates on failover
Hello everybody,
I have looked around for this answer for a while, but I havent found anything that can fix my problem.
In a one-armed scenario, I have 2 Big-IP LTMs configured in an Active/Passive config. I have multiple virtual servers configed and they are working relatively well. When I failover to my standby F5 device (which is connected to a different Cisco switch) failover completes on the F5 devices but my new active LTM does not offer the Virtual Servers service. In summary: I can ping a virtual server (ie, Sharepoint) prior to failover, but after failover it does not ping.
My networking guys looked on the switch for the standby unit that wont work, and they are not seeing the Virtual Servers MACs in the ARP table.
I saw a previous post about not having portfast on the ports, but we have that configured as it is an access port w/out vlan tagging.
Any ideas? I reviewed the Active/Passive set up manual again, but everything looks good in the HA config. The Virtual Address List do have the ARP checkbox enabled.
Thanks!

- hooleylistCirrostratusThanks for confirming the fix. I didn't realize you were on 11.x. Here's a related SOL for people upgrading to 11.x from previous versions:
