Usage Guidelines
• Configuring a max-group value will have no affect on existing group memberships until the member-
ships are refreshed on the port/VLAN instance 
• The configuration is allowed even when the ip multicast status is disabled. 
• If the num and action parameters are not specified, then the limit is removed.
• The max-group configuration on a VLAN will override the global configuration.
• IGMP zapping must be enabled when the max-group limit is enabled and the action is dropped.
