Command Usage
• The IGMP filtering profile must first be created with the
ip igmp profile
command before being able to assign it to an interface.
• Only one profile can be assigned to an interface.
• A profile can be assigned to a trunk interface. When ports are configured as
trunk members, the trunk uses the filtering profile assigned to the first port
member in the trunk.
Example
ip igmp max-groups
This command sets the IGMP throttling number for an interface on the switch. Use
the
no
form to restore the default setting.
Syntax
ip igmp max-groups
number
no
ip igmp max-groups
number
- The maximum number of multicast groups an interface can join
at the same time. (Range: 0-64)
Default Setting
64

Interface Configuration
Command Usage
• IGMP throttling sets a maximum number of multicast groups that a port can
join at the same time. When the maximum number of groups is reached on a
port, the switch can take one of two actions; either “deny” or “replace.” If the
action is set to deny, any new IGMP join reports will be dropped. If the action
is set to replace, the switch randomly removes an existing group and replaces
it with the new multicast group.
• IGMP throttling can also be set on a trunk interface. When ports are
configured as trunk members, the trunk uses the throttling settings of the first
port member in the trunk.
