MLD and MLD Snooping Introduction and Commands
Software Reference for x310 Series Switches
32.22 AlliedWare Plus TM Operating System - Version 5.4.4C C613-50046-01 REV A
ipv6 mld snooping
Use this command to enable MLD Snooping. When this command is issued in the Global
Configuration mode, MLD Snooping is enabled globally for the switch. When this
command is issued in Interface mode for a VLAN then MLD Snooping is enabled for the
specified VLAN. Note that MLD Snooping is enabled on the VLAN only if it is enabled
globally and on the VLAN.
Use the no variant of this command to globally disable MLD Snooping in Global
Configuration mode, or for the specified VLAN interface in Interface mode.
Syntax ipv6 mld snooping
no ipv6 mld snooping
Default By default, MLD Snooping is enabled both globally and on all VLANs.
Mode Global Configuration and Interface Configuration for a specified VLAN interface or a range
of VLAN interfaces.
Usage For MLD Snooping to operate on particular VLAN interfaces, it must be enabled both
globally by using this command in Global Configuration mode, and on individual VLAN
interfaces by using this command in Interface Configuration mode (Both are enabled by
default).
MLD requires memory for storing data structures, as well as the hardware tables to
implement hardware routing. As the number of ports, VLANs, static and dynamic groups
increases then more memory is consumed. You can track the memory used for MLD with
the command:
Static and dynamic groups (LACP), ports and VLANs are not limited for MLD. For VLANs,
this allows you to configure MLD across more VLANs with fewer ports per VLAN, or fewer
VLANs with more ports per VLAN. For LACPs, you can configure MLD across more LACP
groups with fewer ports per LACP, or fewer LACP groups with more ports per LACP.
Examples To configure MLD Snooping on the VLAN interface vlan2, enter the following
commands:
Note There is a 100 MLD interface limit when applying MLD commands to multiple
VLANs. Only the first 100 VLANs have the required multicast structures added
to the interfaces that allow multicast routing. x
310 series switches have a 128
MLD group limit for (*, G) and (S,G) entries. See the limits for MLD interfaces
depending on the number of VLANs, ports, static and dynamic groups as
shown in the relevant product data sheet for your switch.
