I just updated the IOS on a Cisco 3750G switch. When I rebooted, the Node went red in NPM and still remains red. The switch in question is in a DMZ. I can ssh into the switch and ping the switch from the core switch on the inside of the firewall no problem. I cannot ping the switch from my NPM server which hangs off of the core switch mentioned before. The switch is up, why is NPM not seeing that? I even deleted the Node from NPM and readded. I am polling the Node via SNMP, and the test works every time. Does anyone have any ideas?
Thanks...Mike
