ARP/MAC Tables Not Updating on Core Switches After F5 LTM Failover (GARP Issue?)

Unfortunately I'm not able to do this at this time as these boxes are up and running in production. We performed a failover test last night during a scheduled maintenance window in our DEVQA environment. We are however SPANing all network traffice (including ARP) on our network and I'm looking into the capture file to see what was sent during that duration.
