ip igmp snooping host-aging-time seconds
no ip igmp snooping host-aging-time
default ip igmp snooping host-aging-time
Aging time. The unit is second. The value ranges from 1 to 65,535.
The default is 260 seconds.
Global configuration mode
The aging time of a dynamic port is set by the system when the port receives an IGMP packet from the
host for joining a certain IP multicast group.
When such an IGMP packet is received, the system resets the aging timer for the port. The duration of
this timer is determined by host-aging-time. If the timer expires, the system determines that there is
no host in this port for receiving multicast packets. The multicast device removes the port from the
IGMP Snooping group. After the ip igmp snooping host-aging-time command is executed, the aging
time will be determined by host-aging-time. This command takes effect only after the system receives
the next IGMP packet. This command does not change the current aging time.
The following example sets the aging time to 30 seconds.
Ruijie(config)# ip igmp snooping host-aging-time 30
2.10 ip igmp snooping l2-entry-limit
Use this command to set the maximum number of multicast groups.
Use the no or default form of this command to restore the default setting.
ip igmp snooping l2-entry-limit number
no ip igmp snooping l2-entry-limit
default ip igmp snooping l2-entry-limit
