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) numbers when it forwards the Multicast
streams and IGMP/MLD registration messages. This is required so that the
Multicast routers can, in turn, forward the Multicast streams and propagate the
registration messages to other subnets.
To statically configure or see dynamically-detected ports connected to the
Multicast router:
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 port or LAG, select its association type. The options are as follows:
• Static—The port is statically configured as a Multicast router port.
• Dynamic—(Display only) 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 Forbidden is enabled on
a port, Mrouter is not learned on this port (i.e. MRouter Ports Auto-Learn is not
enabled on this port).
• None—The port is not currently a Multicast router port.
STEP 5 Click Apply to update the switch.
