Displaying the IGMP status of an interface
You can display the status of a multicast enabled port by entering a command such as the
following.
Syntax: show ip igmp interface [ve | ethernet <number> <group-address> ]
Enter ve and its <number> or ethernet and its <number> to display information for a specific
virtual routing interface or ethernet interface.
Entering an address for <group-address> displays information for a specified group on the
specified interface.
The report shows the following information.
Mode Indicates current mode of the interface: Include or Exclude. If the interface is
in Include mode, it admits traffic only from the source list. If an interface is in
Exclude mode, it denies traffic from the source list and accepts the rest.
#_src Identifies the source list that will be included or excluded on the interface.
If IGMP V2 group is in Exclude mode with a #_src of 0, the group excludes
traffic from 0 (zero) source list, which means that all traffic sources are
included.
Group If you requested a detailed report, the following information is displayed:
•
The multicast group address
•
The mode of the group
•
A list of sources from which traffic will be admitted (include) or denied
(exclude) on the interface is listed.
•
The life of each source list.
If you requested a tracking report, the clients from which reports were
received are identified.
