Hi player,
I think I may have answered this question in another forum, but I'll give it another go. As long as a virtual server is configured, the LTM will continue to answer echo-requests regardless of the state of the assigned pool. The only way (that I know of) to stop all traffic destined for a virtual address is to use the 'b virtual address arp disable' command. For instance, if you wanted to disable all traffic for virtual address 10.0.0.1 you'd issue the command: b virtual address 10.0.0.1 arp disable. Then enable it again whenever it is needed.
A tangential use case, but I've use this for migrating virtuals between physical boxes.
