All things related to multicast

[Philip Ho <>]

Dear all

Does anyone know how to retrieve multicast receiver IP attaching to
Cisco layer-2 switches 2900XL and 3550? I could only get group MAC
address together with outgoing interface(s) using "sh cgmp" command. (I
know that I could grep it using debug cgmp but is there another
solution?) Thanks a lot!

The sample "sh cgmp" output is as follows:

c2900#sh cgmp
CGMP is running.
CGMP Fast Leave is running.
Default router timeout is 300 sec.


vLAN     IGMP MAC Address   Interfaces
------  -----------------   -----------
    1    0100.5e00.0128      Fa0/1
    1    0100.5e05.0647      Fa0/1 Fa0/4


vLAN     IGMP Router        Expire   Interface
------  -----------------  --------  ----------
    1    0001.4294.cda1     251 sec   Fa0/1
