2.1.6 igmp-snooping fast-leave
Syntax
igmp-snooping fast-leave
undo igmp-snooping fast-leave
View
Ethernet port view
Parameter
None
Description
Using the igmp-snooping fast-leave command, you can enable the function of fast
removing a port from a multicast group. Using the undo igmp-snooping fast-leave
command, you can cancel this configuration.
By default, the fast remove function is disabled.
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 this 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.
Note that, this function takes effect on condition that the client supports IGMP V2. After
configuring this command, when there are multiple users at one port, the leaving of one
user may cause the loss of multicast service of other users in this group.
Example
# Enable the the fast remove function on Ethernet 0/1.
[Quidway-Ethernet0/1] igmp-snooping fast-leave
2.1.7 igmp-snooping group-limit
