ip igmp max-groups
• If you configure the throttling action as replace and set the maximum group limitation, the entries
that were previously in the forwarding table are removed. When the maximum number of entries is
in the forwarding table, the switch replaces a randomly-selected multicast entry with the received
IGMP report.
• When the maximum group limitation is set to the default (no maximum), entering the ip igmp
max-groups {deny | replace} command has no effect.
You can verify your setting by using the show running-config privileged EXEC command and by
specifying an interface.
Examples This example shows how to limit to 25 the number of IGMP groups that a port can join.
Switch(config)# interface gigabitethernet0/2
Switch(config-if)# ip igmp max-groups 25
This example shows how to configure the switch to replace the existing group with the new group for
which the IGMP report was received when the maximum number of entries is in the forwarding table:
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# ip igmp max-groups action replace
