2.1.9 igmp-snooping host-aging-time
Syntax
igmp-snooping host-aging-time seconds
undo igmp-snooping host-aging-time
View
System view
Parameters
seconds: Aging time of multicast group member ports, in the range of 200 to 1000 in
seconds.
Description
Use the igmp-snooping host-aging-time command to configure the aging time of
multicast group member port.
Use the undo igmp-snooping host-aging-time command to restore the default aging
time.
By default, the aging time of multicast group member ports is 260 seconds.
The aging time of multicast group member ports determines the refresh frequency of
multicast group members. In an environment where multicast group members change
frequently, a relatively shorter aging time is required.
Related commands: igmp-snooping.
Examples
# Set the aging time of multicast group member ports to 300 seconds.
