FIGURE 353 Configuring General Settings for IGMP Snooping
Specifying Static Interfaces for a Multicast Router
Use the Multicast > IGMP Snooping > Multicast Router (Add) 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 References
• “Static Multicast Routing” on page 466
Command Usage
IGMP Snooping must be enabled globally on the switch (see “Configuring IGMP Snooping and
Query Parameters” on page 1059) before a multicast router port can take effect.
Parameters
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.
