      life=120, deny 0:

If the tracking and fast leave features are enabled, you can display the list of clients that belong to a
particular group by entering the following command.

device#show ip multicast group 224.1.1.1 tracking

Display group 224.1.1.1 in all interfaces with tracking enabled.

p-:physical, ST:static, QR:querier, EX:exclude, IN:include, Y:yes, N:no

VL70 : 1 groups, 1 group-port, tracking_enabled

Syntax: show ip multicast group [group-address [detail] [tracking]]

If you want a report for a specific multicast group, enter that group's address for group-address .

Enter detail to display the source list of a specific VLAN.

Enter tracking for information on interfaces that have tracking enabled.

The following table describes the information displayed by the show ip multicast group command.

group

The address of the group (destination address in this case, 224.1.1.1)

p-port

The physical port on which the group membership was received.

ST

Yes indicates that the IGMP group was configured as a static group; No means the address was learned
from reports.

QR

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.

life

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 260 seconds. There is no life displayed in INCLUDE mode.

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.

source Identifies the source list that will be included or excluded on the interface.

For example, if an IGMP V2 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.

Displaying IGMP snooping mcache information

To display default, maximum, current, and configured values for system maximum parameters, use
the show default values command. The following output example does not show complete output; it
shows only IGMP mcache values.

device(config)#show default values
