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.
