I am trying to get results from an SNMP walk on 184.108.40.206.220.127.116.11.1 on a netvanta 1524st. I have 4 of them and when I walk the OID, I get an error. Object ID: .18.104.22.168.2.1.17 NULLOBJ: NULL This should be the MAC address of the switch. Can anyone shed some light on this? I have SNMP enabled and RO and RW as public/private.
