I am having issues getting SNMP polling working from an Arbor device to a cisco GSR. Configuration has been verifed as correct on the arbor box and there is similar working elsewhere in the network. Other snmp management stations can get SNMP info no problem. There is only one hop in between the Arbor mgmt. station and that is a L2 switch. Cant figure out the problem. I have no access to arbor box currently.Set up as follows.
Arbor CP --> Has 2 interfaces fa2/46 (vlan 98) and fa2/47 (vlan 99) connected to Switch A.
Switch A trunked to Corea A which has dot1q subinterfaces Gi1/1.98 and Gi1/1.99.
Routing etc working fine.
Static ip route to the loopback of the Arbor box redistributed into ospf
