I'm currently using Network Performance Monitoring interface monitoring on Netvanta 800 series (specifically 814 and 818) devices in my network. After upgrading the software load to vJ04.04, the interfaces that I am monitoring via SNMP are no longer showing statistics. For example, the Min/Max/Avg BPS is showing a constant Rx and Tx of 0 bps. I can correlate this to the time that the upgrade was performed. SNMP walk still functions, and removing and re-adding the interfaces does not fix this issue. Is anyone else experiencing this or has experienced this that knows of a solution?
