I can use the following command to obtain the bridge address table of the stack member 1 (es1) on vlan 100 of a C35XX series switch by using the following command in a Linux machine:
snmpwalk <switch> <community_string@es1@100>
Now, when I upgade the switch to C2950 series, this command is no longer function. Is there any workaround ? The version I used in 12.1(9)EA1
