Just wondering of anyone else has had this issue. We have two set's of 3750's stackwised. Each set is configure with two switches setup with the same loopback ip addr on each pair. Heres the issue:
We can snmp poll the device just fine, ping the loopback ok and the interface goes green. However whenever netmon polls the device it drops the loopback down when its not. From here you can demand poll the switch and it shows the loopback down, but you can ping it back up, then do another demand poll and it reports the interface as being up and looking ok. It will show green until netmon does the normal timed poll then drops it backdown again.
Anyone have any clues how to get this fixed or things I can try???
Sorry would call support but have to get the support contract reinstated but that will take a few weeks to sort out within the company.
