SNOOPING
ipv6 mld snooping
Overview
Use this command to enable MLD Snooping. When this command is issued in the
Global Configuration mode, MLD Snooping is enabled globally for the device.
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.
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.
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:
awplus#
show memory pools nsm | grep MLD
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 interfaces
vlan2-vlan4
, enter the
following commands:
awplus#
configure terminal
awplus(config)#
interface vlan2-vlan4
awplus(config-if)#
ipv6 mld snooping
