CLI – This example modifies the settings for multicast filtering, and then
displays the current status.
Displaying Interfaces Attached to a Multicast Router
Multicast routers that are attached to ports on the switch use information
obtained from IGMP, along with a multicast routing protocol such as
DVMRP or PIM, to support IP multicasting across the Internet. These
routers may be dynamically discovered by the switch or statically assigned
to an interface on the switch.
You can use the Multicast Router Port Information page to display the
ports on this switch attached to a neighboring multicast router/switch for
each VLAN ID.
Command Attributes
• VLAN ID – ID of configured VLAN (1-4094).
• Multicast Router List – Multicast routers dynamically discovered by
this switch or those that are statically assigned to an interface on this
switch.
