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.
