Hi, KC,
It sounds like the upstream switch may not have updated its ARP cache. You could try enabling MAC masquerading on the LTM VLAN that the outbound LDAP connections go out. This should shorten the time it takes for the upstream switches to accept the traffic after a failover.
For details on configuring MAC masquerading and selecting a unique MAC address, you can check two AskF5 solutions:
