So this is the most bizzare behaviour with a very simple configuratio to read MRTG stats off little WS-C2950-24 switch running 12.1(22)EA4
There is absolutely no security and no fancy stuff. Just the most simple configuration.
IF the MRTG host is ON THE SAME network number as the vlan1 interface the switch responds to SNMPWALK just fine and everything works.
However if the MRTG host is NOT on the same network number as the vlan1 interface then the switch is totally dead to ANY snmp packets. It does NOT respond at all, debug does NOT register anything at all, however wireshark does see the incoming packets from the MRTG host with absolytely NO reponse back from the switch?
Total IOS bug or there is a credible "feature" which doesn't allow snmp as long as it has to go via default gateway (not local to the switch net that is)
