Configuration Guide Configuring IGMP Snooping
member port. After the aging time is configured, the aging time of following received IGMP join packets will
be host-aging-time. This configuration takes effect after the next IGMP join packet is received, and the timer
of the port in use will not be refreshed.
 Configuring the Maximum Response Time of a Query Packet
ip igmp snooping query-max-response-time seconds
seconds: Indicates the maximum response time.
Global configuration mode
When an IGMP general Query packet is received, the multicast device will reset the aging time of all the
dynamic member ports, which is query-max-response-time. If the timer expires, the multicast device deems
that no user host for receiving the multicast packet exists under the port, and will delete the port from the
entry of IGMP snooping member port.
When an IGMP profile-specific Query packet is received, the multicast device will reset the aging time of all
the dynamic member ports of the specific profile, which is query-max-response-time. If the timer expires, the
multicast device deems that no user host for receiving the multicast packet exists under the port, and will
delete the port from the entry of IGMP snooping member port.
This configuration takes effect after the next Query packet is received, and the timer in use will not be
refreshed. The timer of an IGMPv3 profile-specific Query packet is not refreshed.
