CLI – This example shows that Port 11 has been statically configured as a
port attached to a multicast router.
Specifying Interfaces Attached to 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 that interface
to join all the current multicast groups. 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/switch.
• Port or Trunk – Specifies the interface attached to a multicast router.
