300s.
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 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: Configure the interface timeout setting for IGMP queries to 100s
Switch (Config)#interface vlan 1
Switch(Config-If-Vlan1)#ip igmp query-timeout 100
16.6.2.2.6 ip igmp static-group
Command: ip igmp static-group <A.B.C.D >
no ip igmp static -group <A.B.C.D >
Function: Join the interface to an IGMP static group; the “no ip igmp static -group”
command cancels the join.
Parameter: <A.B.C.D> are the IP addresses for multicast groups.
Default: Do not join 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 join-group” command.
Example: Specify interface vlan1 to join static group 224.1.1.1.
Switch (Config)#interface vlan 1
Switch(Config-If-Vlan1)#ip igmp static-group 224.1.1.1
16.6.2.2.7 ip igmp version
Command: ip igmp version <version>
no ip igmp version
Function: Configure the IGMP version of the interface; the “no ip igmp version”
command restores the default setting.
Parameter: <version> is the IGMP version configured, v1 and v2 are supported at
present.
Default: The default version number is v2.
