IGMP Snooping allows the switch to forward multicast traffic only to those ports that request it. IGMP
Snooping prevents multicast traffic from being flooded to all ports. The switch learns which server hosts
are interested in receiving multicast traffic, and forwards it only to ports connected to those servers.

igmpv3
Displays the IGMPv3 Snooping menu.
timeout <1-255>
Sets the Maximum Response Time (MRT) for IGMP hosts. MRT is one of the
parameters used to determine the age out period of the IGMP hosts.
Increasing the timeout increases the age out period.
The range is from 1 to 255 seconds. The default is 10 seconds
mrto <1-600>
Configures the age-out period for the IGMP Mrouters in the Mrouter table. If
the switch does not receive a General Query from the Mrouter for mrto
seconds, the switch removes the multicast router from its Mrouter table.
The range is from 1 to 600 seconds. The default is 255 seconds.
qintrval <1-600>
Sets the IGMP router query interval. The range is 1-600 seconds. The default
value is 125. seconds
robust <2-10>
Configures the IGMP Robustness variable, which allows you to tune the
switch for expected packet loss on the subnet. If the subnet is expected to
be lossy (high rate of packet loss), then increase the value. The default value
is 2.
flood disable|enable
Configures the swich to flood unregistered IP multicast reports to all ports.
