Parameter: <interval>
is interval of specified group query, range from 1000ms to
25000ms; the value is integer times of 1000ms, namely if input value is not integer times
of 1000ms, the system autometicly changes to integer times of 1000ms.
Default:
Default: 1000ms
Command Mode:

Example:
Configure interface vlan1 IGMP last-member-query-count to 2000.
Switch (Config)#int vlan 1
Switch (Config-if-vlan1)#ip igmp last-member-query-interval 2000
17.6.3.4 ip igmp limit
Command: ip igmp limit <state-count>
no ip igmp limit
Function:
Configure limit IGMP state-count on interface; the “
no ip igmp limit
”
command cancels the value of user manual configuration, and restores default value.
Parameter: <state-count>
is maximum IGMP state reserved by interface, range from 1
to 65000
Default:
Default: 0, no limit.
Command Mode:
Interface Configuration Mode
Usage Guide:
After configuring mamimum state state-count, interface only saves states
which are not more than state-count groups and sources. If it reaches upper limit of
state-count, it does not deal with when receiving related new group member indentity
report. If it has saved some IGMP group states before configuring the command, it
deletes all of the states, and then immediately transmits IGMP general query to collect
the member identity report which is not more than state-count group. Static state and
static source are not in the limit
Example:
Configure interface vlan1 IGMP limit to 4000.
Switch (Config)#int vlan 1
Switch (Config-if-vlan1)#ip igmp limit 4000
17.6.3.5 ip igmp join-group
Command:ip igmp join-group <A.B.C.D >
no ip igmp join-group <A.B.C.D >
Function:
Configure interface to join some IGMP group; the “no ip igmp join-group”
command cancels this join
Parameter: <A.B.C.D>:
is group address
Default:
Do not join
Command Mode:
Interface Configuration Mode
Usage Guide:
When the switch is the HOST, the command configures HOST to join
