[c-nsp] The problem of Bridge MIB on Cisco2924

Hello, everyone:

I'm using Bridge MIB to get the MAC-Port mapping in my switch (Catalyst
2900xl, IOS 12.0(5.1)XP ). I use
mgmt.mib-2.dot1dBridge.dot1dTp.dot1dTpFdbTable ( to get
such mapping. The problem is I can only get the mapping from the default
vlan (vlan1). I used "show mac" in the command line and found there're
mappings in other vlans.  I tried to use community indexing as "snmpwalk -v
2c -c public at 3 .", where public at 3 eans
vlan3 and is the switch's management IP. But it always replies
"Timeout: No response from". Even I use the same command with
indexing to vlan1, the same reply.


I searched in the web and found some people met such problem before, but I
cannot search a solution. Does anybody here met such problem and any
solutions for it? Thanks a lot!
