CREATE IP IGMP DESTINATION
Syntax CREATE IP IGMP DESTINATION=ipaddress INTERFACE=interface
where:
■ipaddress is an existing IGMP group destination address.
■interface is the name of the interface over which multicast data is forwarded.
■
Description This command creates a static multicast association to forward multicast data from a multicast group to one or more ports.
The DESTINATION parameter specifies the IP address from where multicast data is forwarded.
The INTERFACE parameter specifies the interface over which multicast data is forwarded.
The static IGMP association identified by the DESTINATION and INTERFACE parameters must not already exist.
The PORT parameter specifies the ports through which multicast data is forwarded. If any of the ports specified in the port list are not valid ports for the specified interface, an error message is displayed. An empty port list can be specified by giving no value to the PORT parameter. Ports may be added later using the ADD IP IGMP DESTINATION command. If ALL is specified, or if the PORT parameter is not entered, all ports belonging to that interface will forward multicast data.
Since static IGMP associations are identified by the combination of destination and interface, one destination or interface may belong to several different associations. Also, ports may belong to several associations if there are overlapping VLANs. There is no conflict with existing standard (dynamic) IGMP hosts: if a new static association’s port already has a dynamic IGMP host, the new static entry will replace it.
IGMP destinations added with this command will never time out. They are removed with the DESTROY IP IGMP DESTINATION command.
Examples To forward multicast data to 224.1.2.3 out ports 1 to 4 using vlan1, use the command:
CREATE IP IGMP DESTINATION=224.1.2.3 INTERFACE=VLAN1
