max-groups action
This command sets the IGMP throttling action for an interface on the switch.
Syntax
ip igmp max-groups action {deny | replace}
deny - The new multicast group join report is dropped.
replace - The new multicast group replaces an existing group.
Default Setting
Deny
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
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.
Example
Console(config)#interface ethernet 1/1
Console(config-if)#ip igmp max-groups action replace
Console(config-if)#
ip multicast-data-drop This command drops all multicast data packets. Use the no form to disable this
feature.
