UDP port 161 (snmp) when routing is enabled on 2920

Hi, first post so be kind!


I've got an issue relating to snmp on a few of my 2920's.


When routing is enabled, UDP port 161 seems to close up preventing my network monitoring tool from getting any response from the switch in question. On my 2920's on the same subnet without routing enabled, UDP port 161 remains open. So my monitoring tool works fine and the switch responds to snmp queries.


Any help would be much appreciated!
