Then on a Linux machine with net-snmp installed, I tried to get that mac-address-table with the following SNMP command:
[root@99 ~]# snmptable -m /usr/share/snmp/mibs/Bridge.mib -c public -v2c 172.16.6.2 .18.104.22.168.22.214.171.124.3
SNMP table: BRIDGE-MIB::dot1dTpFdbTable

As you can see, it only displays the mac-address-table under VLAN1, not the whole mac-address-table, it's said that you have to use community string indexing to get the mac-address-table under each VLAN, but I tried and failed, as indicated by the following output:
I tried community string indexing on another Catalyst 4000 L3 switch, and successfully got the mac-address-table of each VLAN, so why can't I get it on the Catalyst 2924 switch? Doesn't Catalyst 2924 switch (or the installed IOS) support community string indexing, or I didn't configure it properly? And is there any other way that I can get the whole mac-address-table on a switch with SNMP commnads?
