Quidway S8500 Series Routing Switches Chapter 4 IGMP Configuration Commands
Huawei Technologies Proprietary
4-11
This command is valid only when the query router runs IGMP v2. If the host runs IGMP
v1 , it does not send an IGMP Leave message when it leaves a group, so this command
is invalid for the IGMP query router.
Related command: igmp robust-count and display igmp interface.
Example
# Set the query interval at the Vlan-interface10 as 3 seconds.
<Quidway> system-view
System View: return to User View with Ctrl+Z.
[Quidway]interface vlan-interface 10
[Quidway-Vlan-interface10] igmp lastmember-queryinterval 3

seconds: Maximum response time in the IGMP query messages in second in the range
from 1 to 25. By default, the value is 10 seconds.
Description
Use the igmp max-response-time command to configure the maximum response
time contained in the IGMP query messages.

The maximum query response time determines the period for a router to quickly detect
that there are no more directly connected group members in a LAN.
