Viprion2400-remove bad card slot 1, slot 2 does not send any monitor probes-all Vir servers down!

Thanks for your answer-interface definitions were correct on slot 2: 2/1.1 and 2/1.2 were up and available in a port channel(one member being active on slot 2, the others down on slot 1 which was absent). Slot 2 saw all interfaces undefined on slot 1 which it should since slot 1 wasnt plugged in.

what I neglected to mention: virtual servers and pool members could be pinged from CLI from subject LTM when only one slot was active but no monitor traffic was sent, and thus all virtual servers down on secondary. So there had to be network connectivity in the data plane

I agree it sounds like a bug but if youre on v11 and it you still saw it, bug still may be unresolved.
