I have two Cisco Nexus 5548's set up in a VPC and we are using NPM (11.52) to monitor and one of the 5548's is showing as being down but in reality it is not. We are using snmp v3, although I tried to
to just use the ICMP option and it is still showing as being down. It allows me to add the device scans the interfaces and adds it but shortly there after the node goes red. I did notice it takes longer to recognize the switch in comparison
to the other 5548. Thanks
