multicast group, the value of timer is selected random from 0 to maximum response time, the host
will transmit member report message of the multicast group. Reasonable configuring maximum
response time, it can make host quickly response query message. The router can also quickly
grasp the status of multicast group member.
Example:
configure the maximum period responding to the IGMP query messages to 20s
Switch (config)#interface vlan 1
Switch(Config-if-Vlan1)#ip igmp query- max-response-time 20
44.9.11 ip igmp query-timeout
Command:
ip igmp query-timeout <time_val>
no ip igmp query-timeout
Function:
Configure IGMP query timeout of interface; the “no ip igmp query-timeout” command restores
default value.
Parameter:
<time_val> is IGMP query-timeout, value range from 60s to 300s.
Default:
255s.
Command Mode:
Interface Configuration Mode
Usage Guide:
When multi-running IGMP switches are exist on sharing network, a switch will be voted as query
processor on the sharing network, and other switches will be a timer monitoring the state of query
processor; It still does not receive query message transmitting by query processor over query
time-out, thus it re-votes another switch as new query processor.
Example:
Configure timeout of IGMP query message on interface to 100s.
Switch (config)#interface vlan 1
Switch(Config-if-Vlan1)#ip igmp query-timeout 100
44.9.12 ip igmp robust-variable
Command:
