DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch CLI Manual
280
Example usage:
To disable IGMP snooping on the switch:
DGS-3450:admin# disable igmp_snooping
Command: disable igmp_snooping
Success.
DGS-3450:admin#
create igmp_snooping static_group
Purpose
Used to configure an IGMP snooping multicast static group.
Syntax
create igmp_snooping static_group [vlan<vlan_name 32> | vlanid <vlanid_list> ] <
ipaddr >
Description
This command allows you to create an IGMP snooping static group. Member ports can be
added to the static group. The static member and the dynamic member port form the member
ports of a group.
The static group will only take effect when IGMP snooping is enabled on the VLAN. For those
static member ports, the device needs to emulate the IGMP protocol operation to the querier,
and forward the traffic destined to the multicast group to the member ports.
For a layer 3 device, the device is also responsible to route the packet destined for this
specific group to static member ports.
The static member port will only affect V2 IGMP operation.
The Reserved IP multicast address 224.0.0.X must be excluded from the configured group.
The VLAN must be created first before a static group can be created.
Parameters
vlan_name
- Specify the name of the VLAN on which the router port resides.
ipaddr
- Specify the multicast group IP address (for Layer 3 switch).
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To create an IGMP snooping static group for “vlan1”, group 239.1.1.1:
DGS-3450:admin# create igmp_snooping static_group vlan vlan1 239.1.1.1
Command: create igmp_snooping static_group vlan vlan1 239.1.1.1
Success.
DGS-3450:admin#
delete igmp_snooping static_group
Purpose
Used to delete a IGMP snooping multicast static group.
Syntax
delete igmp_snooping static_group [vlan<vlan_name 32> | vlanid <vlanid_list> ]
<ipaddr>
Description
The deletion of an IGMP snooping static group will not affect the IGMP snooping dynamic
member ports for a group.
Parameters
vlan
- Specify the name of the VLAN on which the router port resides.
vlanid
- Specify the ID of the VLAN on which the router port resides.
ipaddr
- Specify the multicast group IP address (for Layer 3 switch).
