I have a cisco IE1000 configured with SNMP v3 and the management VLAN is 12, I can access the switch over the network and added it to the NPM console as a managed node.
It allows me to select interfaces to monitor, however it shows the management vlan as down and will not show L2 and L3 connnections on the atlas maps.
I logged a call with support who logged at the SNMP walk details and found this, any suggestions?
I have spoke with colleagues about the case. The device is returning an
operational staus value of 2(down) for VLAN 12
OID for operational status.
This is from your SNMP walk
.220.127.116.11.18.104.22.168.1.8.12 = INTEGER: 2
12 indicates the VLAN. I understand that you are able to ping and the show run command shows the VLAN as up but you will need to investigate why it is sending a status of down in the SNMP walk.
