IGMP Filtering and Throttling
– 613 –
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
Default Setting
Disabled
Command Mode
Interface Configuration (Ethernet)
Command Usage
This command can be used to drop any query packets received on the specified
interface. If this switch is acting as a Querier, this prevents it from being affected by
messages received from another Querier.
Example
Console(config)#interface ethernet 1/1
Console(config-if)#ip igmp query-drop
Console(config-if)#
show ip igmp
authentication
