19.6.2.2.3 ip igmp query-interval
Command: ip igmp query-interval <time_val>
no ip igmp query-interval
Function: Sets the interval for sending IGMP query messages; the "no ip IGMP query interval"
command restores the default setting.
Parameters: <time_val> is the interval for sending IGMP query packets, ranging from 1 to 65535
seconds.
Default: The default interval for sending IGMP query messages is 125 seconds.
Command mode: Interface Mode
Usage Guide: When a multicast protocol is enabled on an interface, IGMP query message will be
sent at regular interval from this interface. This command is also used to configure
the query period.
Example: Setting the interval for sending IGMP query messages to 10 seconds..
Switch (Config)#interface vlan 1
Switch(Config-If-Vlan1)#ip igmp query-interval 10
19.6.2.2.4 ip igmp query-max-response-time
Command: ip igmp query-max-response-time <time_val>
no ip igmp query- max-response-time
Function: Sets the maximum time for an interface to response to an IGMP query; the "no ip igmp
query-max-response-time" command restores the default setting.
Parameters: <time_val> is the maximum interface response time for IGMP queries, ranging from
1 to 25 seconds.
Default: The default value is 10 seconds.
Command mode: Interface Mode
Usage Guide: On receiving a query message from the switch, the host will set a counter for each
multicast group it belongs to, the counter value is random from 0 to the maximum
response time. When the value of any counter decreases to 0, the host will send the
member report message for the multicast group. Setting the maximum response time
sensibly enables fast responses of a host to query messages, the router can also get
the existing status of the multicast group members.
Example: Setting the maximum IGMP query response time to 20 seconds.
Switch (Config)#interface vlan 1
Switch(Config-If-Vlan1)#ip igmp query- max-response-time 20
19.6.2.2.5 ip igmp query-timeout
Command: ip igmp query-timeout <time_val>
no ip igmp query-timeout
Function: Set the timeout interval for an interface to response to an IGMP query; the "no ip igmp
query-timeout" command restores the default setting.
Parameters: < time_val> is the time to timeout an IGMP query, the valid range is 60 to 300
seconds..
Default: The default value is 265 seconds.
Command mode: Interface Mode
Usage Guide: In a shared network with several routers running IGMP, one switch will be selected
