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
