Determine the multicast group and multicast source addresses.
Setting aging timers for dynamic ports
If the memberships of multicast groups change frequently, you can set a relatively small value for the
aging timer of the dynamic member ports. If the memberships of multicast groups change rarely, you
can set a relatively large value.

Configuring static ports
You can configure a port as a static port for the following purposes:
•
To make all the hosts attached to the port receive multicast data addressed to a multicast group,
configure the port as a static member port for the multicast group.
•
To make the Layer 2 device attached to the port forward all received multicast traffic on the port,
configure the port as a static router port.
Configuration guidelines
•
A static member port does not respond to queries from the IGMP querier. When you configure a
port as a static member port or cancel this configuration on the port, the port does not
unsolicitedly send any IGMP report or an IGMP leave message.
•
Static member ports and static router ports never age out. To remove such a port, use the
corresponding
undo
command.
