Does anyone knows the mib ID of the following command "show mac-address multicast count"? I am able to run this command on my switch but when i use GetIf to retrieve the value, i am not able to find the value.

I have this problem too.

The "show mac-address-table multicast vlan" is supported on a layer 2 only switch, but the table it displays will generally be empty.

A host generating lots of multicast traffic will not cause us to add entries to the layer 2 multicast table. We "learn" multicast entries only through IGMP snooping. It is only for unicast traffic that we learn entries by looking at the source addresses of the packets we receive.

Actually I wanted to find out the numberof mac-address used by the multicast traffic. Currently I am able to retrieve the value via the command show mac-address multicast count. But I wanted to use the snmp mibs to retrieve this value instead so that I can plot the graph on the number of mac-address for multicast traffic.

I think you should specify after that interface also like this: VLAN 1

Switch# show mac-address-table multicast vlan 1 count

Multicast MAC Entries for vlan 1: 4

Switch#
