Layer 2 IGMP (Snooping and Query)

CLI
– This example shows that Port 11 has been statically configured as a port
attached to a multicast router.
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.
•
Unit
– Stack unit. (Range: 1-8)
•
Port
or
Trunk
– Specifies the interface attached to a multicast router.
Web
– Click IGMP Snooping, Static Multicast Router Port Configuration. Specify the
interfaces attached to a multicast router, indicate the VLAN which will forward all the
corresponding multicast traffic, and then click Add. After you have finished adding
interfaces to the list, click Apply.
