55-4 create mld_snooping static_group
Description
This command is used to create an MLD snooping multicast 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 MLD snooping is enabled on the VLAN. For those static
member ports, the device needs to emulate the MLD 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 MLD operation. The Reserved IP multicast addresses
FF0x::/16 must be excluded from the configured group. The VLAN must be created first before a
static group can be created.
Format
create mld_snooping static_group [vlan <vlan_name 32> | vlanid <vlanid_list>] <ipv6addr>
Parameters
vlan - Specify the name of the VLAN on which the static group resides.
<vlan_name 32> - Specify the VLAN name. The maximum length is 32 characters.
vlanid - Specify the VLAN ID list.
<vlanid_list> - Specify the VLAN ID list.
<ipv6addr> - Specify the multicast group IPv6 address.
Restrictions
Only Administrator, Operator and Power-User level users can issue this command.
Example
To create an MLD snooping static group on vlan1, group FF1E::1:
DGS-3420-28SC:admin#create mld_snooping static_group vlan vlan1 FF1E::1
Command: create mld_snooping static_group vlan vlan1 FF1E::1
Success.
DGS-3420-28SC:admin#
55-5 config mld_snooping static_group
Description
This command is used to configure an MLD snooping static group on the switch. When a port is
configured as a static member port, the MLD protocol will not operate on this port. Therefore,
suppose that a port is a dynamic member port learned by MLD. If this port is configured as a static
member later, then the MLD protocol will stop operating on this port. The MLD protocol will resume
once this port is removed from static member ports. The static member port will only affect V1
MLD operation.
