Defining Multicast Router Ports
A Multicast router (Mrouter) port is a port that connects to a Multicast router. The
switch includes the Multicast router port(s) when it forwards the Multicast streams
and IGMP/MLD registration messages. This is required in order for all the Multicast
routers can in turn forward the Multicast streams and propagate the registration
messages to other subnets.
On this page, it is possible to statically configure or dynamically detect which
ports are connected to Mrouters.
To define Multicast router ports:
STEP 1 Click Multicast > Multicast Router Port. The Multicast Router Port Page opens.
STEP 2 Enter some or all of following query filter criteria:
• VLAN ID equals to—Select the VLAN ID for the router ports that are
described.
• IP Version equals to—Select the IP version that the Multicast router
supports.
• Interface Type equals to—Select whether to display ports or LAGs.
STEP 3 Click Go. The interfaces matching the query criteria are displayed.
STEP 4 For each interface, select its association type. The options are as follows:
• Static—The port is statically configured as a Multicast router port.
• Dynamic—The port is dynamically configured as a Multicast router port by
a MLD/IGMP query. To enable the dynamic learning of Multicast router ports,
go to the Multicast > IGMP Snooping Page, and the Multicast > MLD
Snooping Page
• Forbidden—This port is not to be configured as a Multicast router port, even
if IGMP or MLD queries are received on this port. If Auto Detect Mrouter
Ports is enabled on this port, the configuration does not succeed.
• None—The port is not currently a Multicast router port.
STEP 5 Click Apply to update the switch.
