I am trying to get results from an SNMP walk on 18.104.22.168.22.214.171.124.1 on a netvanta 1524st. I have 4 of them and when I walk the OID, I get an error. Object ID: .126.96.36.199.2.1.17 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.
