After spending more than a few days troubleshooting this on a live production network, I thought I'd share. If you're a network engineer troubleshooting a similar problem, hopefully Google brings you here for a quick fix before you open a support ticket.
FTOS 7.6.1 on Force10 hardware may not support mac masquerading when the mac address changes ports . When a mac address floats from one port to another, as it would during a Cisco ASA failover, the arp table is not updated. In order to achieve this functionality you need to enable the following command in your switch config:
mac-address-table station-move refresh-arp
Problem solved.
