17.13 ip igmp snooping max-groups Description The ip igmp snooping max-groups command is used to configure the maximum number of groups that a port can join in. The ip igmp snooping max-groups action is used to configure the action that the port takes when it receives an IGMP report message and the maximum number of entries is in the forwarding table. To remove the maximum group limitation and return to the default of no limitation on the specified port, please use the no ip igmp snooping max-groups command. To return to the default action of dropping the report, please use the no ip igmp snooping max-groups action command. These commands only apply to the dynamic multicast groups. Syntax ip igmp snooping max-groups maxgroup ip igmp snooping max-groups action { drop | replace } no ip igmp snooping max-groups no ip igmp snooping max-groups action Parameter maxgroup -- Specify the maximum numbers of groups that the port can join. It ranges from 0 to 1000 and the default value is 1000. drop -- When the number of the dynamic multicast groups that a port joins has exceeded the max-group, the port will not join any new multicast group. replace -- When the number of the dynamic multicast groups that a port joins has exceeded the max-group, the newly joined multicast group will replace an existing multicast group with the lowest multicast group address. Command Mode Interface Configuration Mode (interface fastEthernet / interface range fastEthernet /interface gigabitEthernet / interface range gigabitEthernet / interface port-channel / interface range port-channel) Privilege Requirement Only Admin, Operator and Power User level users have access to these commands.
