[Description]
Applies the IPv4 access list to the applicable interface, and limits membership to which multicast receivers may join.
If this command is executed with the "no" syntax, cancels the limitations on a multicast group.
[Note]
The IPv4 access list should be set to allow (permit) the multicast group that will be added.
[Example]
Limit the range of multicast groups that can join within 225.2.0.0 to 225.2.255.255.
SWX3220(config)#access-list 1 permit any 225.2.0.0 0.0.0.255 any
SWX3220(config)#interface vlan2
SWX3220(config-if)#ip igmp access-group 1

[Description]
Sets the maximum number of registrants for IGMP group membership.
This sets the maximum number system-wide in global configuration mode, and the maximum number for the interface in
interface mode.
Applying the IPv4 access list will allow for specific multicast groups to be excluded from the maximum number limitation.
If this command is executed with the "no" syntax, deletes the maximum number of registrants.
[Note]
The IPv4 access list should be set to allow (permit) the multicast group that will be excluded.
[Example]
This sets the maximum number of registrants for IGMP group membership to 100, and excludes multicast group 239.0.0.1 from
the limitations.
SWX3220(config)#access-list 1 permit any 239.0.0.1 0.0.0.0 any
SWX3220(config)#ip igmp limit 100 except 1
8.5.13 Set IGMP group membership static entry
