Hello,
I need to access to the complete list of multicast subscribers for one VLAN, not just the last reporter.
Does anybody know how to get it through commands or SNMP?

Oscar,
I am not sure you will be able to get that information. From the router point of view, all we care about is whether there is an interested subscriber or not, hence the last reporter.

Hello Oscar,
with IGMPv2 only L2 switches have the complete picture for the report suppression feature:
on all L2 switches taking part in the vlan including the c7600 you can use:
you need to refer to the L2 multicast address.
See this example from a C7609
sh mac-address-table multicast vlan 617 | beg 0100.5e48.6403
617 0100.5e48.6403 static Yes - Po1,Po277,Router
617 0100.5e48.6402 static Yes - Po1,Po277,Router
617 0100.5e48.6406 static Yes - Po1,Po277,Router
617 0100.5e00.0128 static Yes - Po1,Po277,Router
Hope to help
