Specifying Static
Interfaces for a
Multicast Router
Use the Multicast > IGMP Snooping > Multicast Router (Add Static Multicast Router)
page to statically attach an interface to a multicast router/switch.
Depending on 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 the switch, the
interface (and a specified VLAN) can be manually configured 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 Usage
IGMP Snooping must be enabled globally on the switch (see “Configuring IGMP
Snooping and Query Parameters” on page 440) before a multicast router port can
take effect.
