member.
Example:
onfigure 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
17.6.3.8 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:
Default: 265s.
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
17.6.3.9 ip igmp static-group
Command:ip igmp static-group <A.B.C.D > [source <A.B.C.D >]
no ip igmp static -group <A.B.C.D > [source <A.B.C.D >]
Function:
Configure interface to join some IGMP static group; the “no ip igmp
static-group” command cancels this join.
Parameter: <A.B.C.D>
is group address;;
Source
<A.B.C.D>
expresses SSM source address of configuration.
Default:
Do not join static group
Command Mode:
Interface Configuration Mode
Usage Guide:
When configuring some interface to join some static group, it will receives
about the multicast package of the static group whether the interface has a real receiver
or not; that is, if configuring the interface to join static group 224.1.1.1, the interface
always receives about multicast packet about group 224.1.1.1 whether the interface has
a receiver or not. Carefully, it is the diffence between the command and ip igmp
join-group command.
