Command Usage
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.
Example
Console(config)#interface ethernet 1/1
Console(config-if)#ip igmp max-groups action replace
Console(config-if)#
ip igmp query-drop This command drops any received IGMP query packets. Use the no form to restore
the default setting.
Syntax
[no] ip igmp query-drop [vlan vlan-id]
vlan-id - VLAN ID (Range: 1-4094)
Default Setting
Disabled
