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
Console(config)#interface ethernet 1/1
Console(config-if)#ip igmp max-groups 10
Console(config-if)#
ip igmp 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
