On the LTM under Network >> ARP >> Dynamic List there you will see the arp table. You can select all the ip addresses associated with the MAC and select delete.

I tried that but form command line using arp -d but it doesn't work, as the problem as I see it is that other devices know the Virtual Server address with the wrong mac address and they need to be told that the mac of that IP address has changed. Somehow that's what happens when the LTM is rebooted.

 

 

I'm using LTM 9.4.6.
