We have two instances of NPM running in our environment. They were both running Version 11.5.2 until recently we upgraded one of them to 12.1. Ever since the upgrade we have now been getting alerts on some of our Cisco switches saying specific interfaces are in a warning state and then go back to up. This is only occurring on the older 11.5.2 NPM as the 12.1 NPM does not show the same alerts for the same devices. The 11.5.2 did not show these until the second instance was upgraded? We have looked at the switch interface and nothing indicates there was a problem. Has anyone else seen this issue? We keep having to troubleshoot the issue every time we get an alert but we have yet to see where this is an actual problem on the switch.
hey.. try removing and re-adding the node back into monitoring.. could be a issue with these pollers.. i have upgraded a few environments to 12.1 and haven't seen this..
You could actually run the 'active diagnostics' to help identity issues
