I have an HP LJ M451 printer on my network and polling is configured for SNMPv1 and that tests good. The node is reported in NPM as red for 100% packet loss. Looking at the node details, network tab, "NPM Network Topology" shows the interface on my network switch is green and the Ethernet interface on the printer is green, but the printer itself is red. This is not the case since we can send a print job to the printer and it prints successfully. "Current Percent Utilization of Each Interface" also shows the Ehternet interface green as well as the Loopback interface as green. Any ideas the node is showing red?
