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.
CLI R EFERENCES
◆ "Static Multicast Routing" on page 1206
C OMMAND U SAGE
IGMP Snooping must be enabled globally on the switch (see "Configuring
IGMP Snooping and Query Parameters" on page 515 ) before a multicast
router port can take effect.
P ARAMETERS
These parameters are displayed:
◆ VLAN – Selects the VLAN which is to propagate all multicast traffic
coming from the attached multicast router. (Range: 1-4093)
◆ Interface – Activates the Port or Trunk scroll down list.
◆ Port or Trunk – Specifies the interface attached to a multicast router.

1.
Click Multicast, IGMP Snooping, Multicast Router.
2.
Select Add Static Multicast Router from the Action list.
3.
Select the VLAN which will forward all the corresponding multicast
traffic, and select the port or trunk attached to the multicast router.
4. Click Apply.
