The ALLGROUP parameter specifies the list of ports able to behave as all- group entry ports. If ALL is specified, all ports are able to behave as all-group entry ports. The default is ALL.

Examples To enable ports 1, 5 and 7 to behave as all-group entry ports, use the command:

ENABLE IP IGMP ALLGROUP=1,5,7

See Also DISABLE IP IGMP ALLGROUP

SHOW IP IGMP

disable ip igmp allgroup

Syntax DISABLE IP IGMP ALLGROUP=[{port-listALL}]

where:

■port-listis a port number, a range of port numbers (specified as n-m), or a comma separated list of port numbers and/or ranges. Port numbers start at 1 and end at m, where m is the highest numbered Ethernet switch port, including uplink ports.

Description This command disables the specified port(s) from acting as a multicast all- group entry ports. Ports that are disabled have a “#” symbol next to the port number in the output of the SHOW IP IGMP command.

Examples To prevent ports 1, 5 and 7 from behaving as all-group entry ports, use the command:

DISABLE IP IGMP ALLGROUP=1,5,7

See Also ENABLE IP IGMP ALLGROUP

SHOW IP IGMP

IGMP Snooping

You can now specify the mode of operation when IGMP Snooping is enabled with the command:

SET IGMPSNOOPING

ROUTERMODE=[ALLDEFAULTIPMULTICASTROUTERNONE]

If ALL is specified, all reserved multicast addresses (i.e. 224.0.0.1 to 224.0.0.255) are treated as router multicast addresses.

If DEFAULT is specified, the following addresses are treated as router multicast addresses:

■IGMP Query, 224.0.0.1

■All routers on this subnet, 224.0.0.2

■DVMRP Routers, 224.0.0.4

■OSPFIGP all routers, 224.0.0.5

■OSPFIGP designated routers, 224.0.0.6
