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.

Example

ip igmp max-groups action

This command sets the IGMP throttling action for an interface on the switch.

Syntax

ip igmp max-groups action {replace | deny}

replace - The new multicast group replaces an existing group.
deny - The new multicast group join report is dropped.

Default Setting

Deny
