Syntax set igmp mode= - set the IGMP mode. Normal is when a L3 device is in the
network and is the IGMP root. The IGMP-L2 is used when there is no L3 device in the network
Syntax show-group – shows the multicast groups
Syntax set-port port=< port|list|range> mode= - set the port
characteristics. Block drops the unregistered multicasts. Forward forwards unregistered multicasts
Syntax show-port – display the port characteristics for IGMP
Syntax show-router – displays detected IGMP-enabled router ports
Syntax set-leave - enables or disables the switch to immediately process a host sending a
leave message rather that wait for the timer to expire
Syntax set-querier - enables or disables a switch as IGMP querier
Syntax set-qi interval= - The IGMP querier router periodically sends general host-query messages.
These messages are sent to ask for group membership information. This is sent to the all-system multicast
group address, 224.0.0.1. The default value is 125 seconds. The valid range can be from 60 to 127
seconds.
Syntax set-qri interval= - The query response interval is the maximum amount of time that can
elapse between when the querier router sends a host-query message and when it receives a response from a
host. The Default value is 10 seconds. The Range can be from 2 to 270 seconds. Restrictions apply to the
maximum value because of an internal calculation that is dependent on the value of the Query Interval.
