Community string indexing error in non-cisco switches

Question

I am trying to retrieve CAM table information from non-cisco switches. I am using D-Link DES 3526 and Brocade fastiron sx 800 switches and installed net-snmp. When I execute the cmd: $snmpwalk -v 2c -c public@[vlanid] [ip-address] 1.3.6.1.2.1.17.4.3.1.1
I am getting TIMEOUT error. I googled for the answer and found that [comm]@[vlanid] is cisco specific. Visit ftp://ftp.cisco.com/pub/mibs/supportlists/wsc1200/wsc1200-communityIndexing.html. So can anyone say how to do community string indexing for non-cisco switches?

Answer 1

So can anyone say how to do community string indexing for non-cisco switches?

This is how to poll Q-BRIDGE-MIB for mac-addresses from the only non-Cisco I have, a DLink DGS-3200. I'm not using [community@vlan] for non-Cisco switches. Indexing BRIDGE-MIB with [community@vlan] only applies to Ciscos.

I expect any non-Cisco switch, which supports Q-BRIDGE-MIB to work the following way.

Polling sysDescr to document the switch under test

[mpenning@tsunami ~]$ # Demo from a DLink DGS-3200 switch
[mpenning@tsunami ~]$ snmpbulkwalk -v 2c -c public -OXsq 172.16.1.2 sysdescr
