Configuring the MLD version for individual ports

You can specify the MLD version for individual ports in a VLAN. For example, the following commands
configure ports 1/4, 1/5, 1/6 and 2/1 to use MLDv2. The other ports use the MLD version specified with
the multicast6 version command, or the globally configured MLD version.

Device(config)#vlan 20

Device(config-vlan-20)#multicast6 port-version 2 ethernet 2/1 ethernet 1/4 to 1/6

Syntax: [no] multicast6 port-version [1 | 2 ] ethernet port-numbers

Configuring static groups

A snooping-enabled VLAN cannot forward multicast traffic to ports that do not receive MLD membership
reports. To allow clients to send reports, you can configure a static group that applies to individual ports
on the VLAN. You cannot configure a static group that applies to the entire VLAN.

The maximum number of supported static groups in a VLAN is 512, and the maximum number of
supported static groups for individual ports in a VLAN is 256. The static group forwards packets to the
static group ports even if they have no client membership reports. Configure a static group for specific
ports on VLAN 20 using commands similar to the following.

device(config)#vlan 20

device(config-vlan-20)#multicast6 static-group ff05::100 count 2 ethe 1/3 ethe 1/5 to 

1/7 

Syntax: [no] multicast6 static-group ipv6-address [ count num] [ port-numbers]

The ipv6-address parameter is the IPv6 address of the multicast group.

The count is optional, which allows a contiguous range of groups. Omitting the count num is equivalent
to the count being 1.

Configuring static router ports

All multicast control and data packets are forwarded to router ports that receive queries. Although router
ports are learned, you can configure static router ports to force multicast traffic to specific ports, even
though these ports never receive queries. To configure static router ports, enter commands such as the
following:

Device(config)#vlan 70

Device(config-vlan-70)#multicast6 router-port ethernet 1/4 to 1/5 ethernet 1/8

Syntax: [no] multicast6 router-port ethernet port-numbers

Disabling static group proxy

A device with statically configured groups acts as a proxy and sends membership reports for its static
groups when it receives general or group-specific queries. When a static group configuration is
removed, the group is immediately deleted from the active group table. However, the device does not
send leave messages to the querier. The querier should age out the group. The proxy activity can be
disabled (the default is enabled).

device(config)#vlan 20

device(config-vlan-20)#multicast6 proxy-off
