group p-port
224.1.1.1 0/1/33
receive reports from 1 clients: (age)
(2.2.100.2 60)
Description
The address of the group (destination address in this case, 224.1.1.1)
The physical port on which the group membership was received.
Yes indicates that the IGMP group was configured as a static group; No means the address
was learned from reports.
Yes means the port is a querier port; No means it is not. A port becomes a non-querier port
when it receives a query from a source with a lower source IP address than the device.
The number of seconds the group can remain in EXCLUDE mode. An EXCLUDE mode changes
to INCLUDE mode if it does not receive an "IS_EX" or "TO_EX" message during a certain period
of time. The default is 140 seconds. There is no life displayed in INCLUDE 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.
Identifies the source list that will be included or excluded on the interface.
For example, if an IGMPv2 group is in EXCLUDE mode with a source of 0, the group excludes
traffic from the 0 (zero) source list, which actually means that all traffic sources are included.
