show ipv6 multicast group match-last-bits

Displays the groups that share the specified number of lowest bits to match with group address for all VLANs on all ports.
Syntax
show ipv6 multicastgroupgroup-addressmatch-last-bitsdecimal
Parameters
group-address
Specifies information for a particular group.
match-last-bitsdecimal
Specifies the number of lowest bits to match with the group address. Valid values range from 1 through 128. Use 32 to match the same MAC address.
Modes

User EXEC mode

Privileged EXEC mode

The show ipv6 multicast group match-last-bits command displays the following information:

Output Field

Description

group

The address of the group.

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.

Examples

The following example shows the groups that shares the same MAC address with group address for all VLANs on all ports. 

device# show ipv6 multicast group ff1e::10:1:1 match-last-bits 32
Display groups sharing same mac address 3333.0001.0001 with group ff1e::10:1:1  for all vlans on all ports.
