Igmp Snooping Example - Digitalchina Networks DCS-3950 series Manual

Example: Switch(config)#ip igmp snooping vlan 2 query- robustness 3
11.2.2.11 ip igmp snooping vlan suppression-query-time
Command: ip igmp snooping vlan <vlan-id> suppression-query-time <value>
no ip igmp snooping vlan <vlan-id> suppression-query-time
Function: Configure the suppression query time. The 'no ip igmp snooping vlan
<vlan-id> suppression-query-time' command restores to the default value
Parameters: vlan-id: vlan id , ranging between <1-4094>
value: query interval, ranging between<1-65535> seconds
Command mode:Global Mode
Default: 255s
Usage Guide: This command can only be configured on L2 general querier. The
Suppression-query-time refers to the period of suppression state in which the querier
enters when receives query from the layer 3 IGMP in the segments.
Example: Switch(config)#ip igmp snooping vlan 2 suppression-query-time 270
11.2.2.12 ip igmp snooping vlan static-group
Command: ip igmp snooping vlan <vlanid> static-group <multicast-IPAddress>
interface {[ethernet|port-channel] <interfaceName>}
no ip igmp snooping vlan <vlanid> static-group <multicast-IPAddress>
interface {[ethernet|port-channel] <interfaceName>}
Function：Configure static-group on specified port of the vlan. The no form of
thecommand cancels this configuration.
Parameters: <vlan-id> is the id number for the VLAN，with its value limited to 1-4094；
<multicast-ip-addr> is the multicast IP address； <interface-name> is the interface which
is the member of the multicasting group.
Default: No configuration static group by default.
Usage Guide: When a group is a static while also a dynamic group, it should be taken as
a static group. Deleting static group can only be realized by the no form of the command.
Example: Configure a static multicast IP address as 224.1.1.1 for VLAN 100. And add
ethernet 0/0/6 to the group.
Switch(Config)#no ip igmp snooping vlan 100 static- group 224.1.1.1 interface eth0/0/6
