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-list
|ALL}]
where:
■
port-list
is 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

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=[ALL|DEFAULT|IP|MULTICASTROUTER|NONE]
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
