Multicast Filtering Commands
This switch uses IGMP (Internet Group Management Protocol) to check for any
attached hosts that want to receive a specific multicast service. It identifies the
ports containing hosts requesting a service and sends data out to those ports only.
It then propagates the service request up to any neighboring multicast switch/
router to ensure that it will continue to receive the multicast service.
Note that IGMP query can be enabled globally at Layer 2, or enabled for specific
VLAN interfaces at Layer 3. (Layer 2 query is disabled if Layer 3 query is enabled.)
Table 115: Multicast Filtering Commands
Command Group Function
IGMP Snooping Configures multicast groups via IGMP snooping or static assignment,
sets the IGMP version, enables proxy reporting, displays current
snooping settings, and displays the multicast service and group
members
Static Multicast Routing Configures static multicast router ports which forward all inbound
multicast traffic to the attached VLANs
IGMP Filtering and
Throttling Configures IGMP filtering and throttling
MLD Snooping Configures multicast snooping for IPv6
IGMP (Layer 3) Configures the IGMP protocol used with multicast routing in IPv4
networks
IGMP Proxy Routing Collects and sends multicast group membership information onto the
upstream interface based on IGMP messages monitored on
downstream interfaces, and forwards multicast traffic based on that
information
MLD (Layer 3) Configures the MLD protocol used with multicast routing in IPv6
networks
MLD Proxy Routing Collects and sends multicast group membership information onto the
upstream interface based on MLD messages monitored on
downstream interfaces, and forwards multicast traffic based on that
information
