as the querier for that shared network, the other switches act as timers monitoring the status of the querier; if no query packet from the querier is received after the query timeout time, a new switch will be elected to be the new querier.
Example: Configuring the interface timeout setting for IGMP queries to 100 seconds. Switch (Config)#interface vlan 1
19.6.2.2.6ip igmp static-group
Command: ip igmp
Function: Joins the interface to an IGMP static group; the “no ip igmp static
Parameters: <A.B.C.D> are the IP addresses for multicast groups.
Default: Not joined to static groups.
Command mode: Interface Mode
Usage Guide: After an interface joins a static group, then the interface will receive multicast packet about that static group regardless of whether there are actual receivers under the interface or not; for instance, if the local interface joins static group 224.1.1.1., then the local interface will keep receiving multicast packets about he group 224.1.1.1 regardless of whether there are receiver of not under the interface. Note the difference between this command and the “ip igmp
Example: Specifing interface vlan1 to join static group 224.1.1.1. Switch (Config)#interface vlan 1
19.6.2.2.7ip igmp version
Command: ip igmp version <version> no ip igmp version
Function: Configures the IGMP version of the interface; the “no ip igmp version” command restores the default setting.
Parameters: <version> is the IGMP version configured, v1 and v2 are supported at present.
Default: The default version number is v2.
Command mode: Interface Mode
Usage Guide: This command is used to provide forward compatibility between different versions. It should be noted that v1 and v2 are not
Example: Configuring the IGMP running on the interface to version 1. Switch (Config)#interface vlan 1
