We are monitoring two Nexus 7k's with NPM. It seems as though, very randomly, interfaces will go from being Up, to Warning, to Unknown, and then Up again a bit later.
Sometimes it works to use Poll Now and they will all come back Up.
This happens on both physical as well as port channel interfaces. Sometimes it is a few interfaces, sometimes it is only 1.
Extra Details
System NX-OS: 5.2(3a)
SNMP version 3 with authentication and privacy.
This does NOT happen on any other Cisco switch/router that we are monitoring.
Has anybody else experienced similar behavior or found a solution to make the Nexus 7k's more stable in NPM?
