Displaying MLD group 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 MLD group values.

Device(config)#show default values

System Parameters     Default    Maximum    Current    Configured

MLD-snoop-group-addr  4096       8192       5000       5000      

To display MLD group information, enter the show ipv6 multicast group command.

Device#show ipv6 multicast group

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

VL1 : 263 grp, 263 grp-port, tracking_enabled

      group                                    p-port ST QR life mode source

1     ff0e::ef00:a0e3                          1/7    N  Y  120  EX   0

2     ff01::1:f123:f567                        1/9    N  Y       IN   1

  

NOTE
In this example, an MLDv1 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.

To display detailed MLD group information, enter the following command.

Device#show ipv6 multicast group ff0e::ef00:a096 detail

Display group ff0e::ef00:a096 in all interfaces in details.

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

VL1 : 1 grp, 1 grp-port, tracking_enabled

      group                                    p-port ST QR life mode source

1     ff0e::ef00:a096                          1/7    N  Y  100  EX   0

    group: ff0e::ef00:a096, EX, permit 0 (source, life):

      life=100, deny 0:

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

Device#show ipv6 multicast group ff0e::ef00:a096 tracking

Display group ff0e::ef00:a096 in all interfaces with tracking enabled.

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

VL1 : 1 grp, 1 grp-port, tracking_enabled

      group                                    p-port ST QR life mode source
