support IP multicasting across the Internet. These routers may be dynamically
discovered by the switch or statically assigned to an interface on the switch.
You can use the Multicast Router Port Information page to display the ports on this
switch attached to a neighboring multicast router/switch for each VLAN ID.
Command Attributes
• VLAN ID – ID of configured VLAN (1-4093).
• Multicast Router List – Multicast routers dynamically discovered by this switch or
those that are statically assigned to an interface on this switch.
Web – Click IGMP Snooping, Multicast Router Port Information. Select the required
VLAN ID from the scroll-down list to display the associated multicast routers.

Specifying Static Interfaces for a Multicast Router

Depending on your network connections, IGMP snooping may not always be able to
locate the IGMP querier. Therefore, if the IGMP querier is a known multicast router/
switch connected over the network to an interface (port or trunk) on your switch, you
can manually configure the interface (and a specified VLAN) to join all the current
multicast groups supported by the attached router. This can ensure that multicast
traffic is passed to all the appropriate interfaces within the switch.
Command Attributes
• Interface – Activates the Port or Trunk scroll down list.
• VLAN ID – Selects the VLAN to propagate all multicast traffic coming from the
attached multicast router.
