Monitoring VLANs with SNMP

[jonhill]

Can someone remind me how I can monitor a VLAN other than VLAN 1 with SNMP I think it's something along the lines of public@....

Any help would be much appreciated.

Thanks

Jon

see the following link on how to get VLAN info from a catalyst using SNMP:

The @ represents community string indexing. So if you wanted to get snmp output for VLAN 200 you would do something like this:

snmpwalk -Os -c public@200 -v 2c 10.1.1.1 dot1dTpFdbAddress

Keep in mind the flags I use above are from my specific snmpwalk utility (net-snmp) but you would add the @ to the comm string and then the value to collect the data
