3.2.3 Configure Maximum Response Time
This task is to manually configure the maximum response time. If the Ethernet switch
receives no report message from a port in the maximum response time, it will remove
the port from the multicast group.
Perform the following configuration in system view.
Table 3-3 Configure the maximum response time
Operation Command
Configure the maximum response
time
igmp-snooping max-response-time
seconds
Restore the default setting
undo igmp-snooping max-response-time
By default, the maximum response time is 10 seconds.
3.2.4 Configure Aging Time of Multicast Group Member
This task is to manually set the aging time of the multicast group member port. If the
switch receives no multicast group report message during the member port aging time,
it will transmit the specific query message to that port and starts a maximum response
timer.
Perform the following configuration in system view.
Table 3-4 Configure aging time of the multicast member
Operation Command
Configure aging time of the
multicast member
igmp-snooping host-aging-time seconds
Restore the default setting
undo igmp-snooping host-aging-time
By default, the aging time of the multicast member is 260 seconds.
3.2.5 Enabling/Disabling the function of fast removing a port from a
multicast group
Normally, at the receiving of the IGMP Leave packet, igmp-snooping sends out
group-specific query packet instead of directly removing a port from a multicast group.
After waiting for a period of time, if it receives no respond, igmp-snooping then
removes the port form the group. By configuring the follwing command,
igmp-snooping removes the port from the multicast group directly at receiving the
IGMP Leave packet. The fast remove function saves bandwidth when only one user
remaining at the port.
