C613-50100-01 REV C Command Reference for x930 Series 1651
AlliedWare Plus™ Operating System - Version 5.4.6-1.x
MLD AND MLD SNOOPING COMMANDS
IPV
6 MLD
ipv6 mld
Overview Use this command to enable the MLD protocol operation on an interface. This
command enables MLD protocol operation in stand-alone mode, and can be used
to learn local-membership information prior to enabling a multicast routing
protocol on the interface.
Use the no variant of this command to return all MLD related configuration to the
default (including MLD Snooping).
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.
x610 series switches have a 256 MLD group limit for (*, G) and (S,G) entries.
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.
The device has a 512 MLD group limit for (*, G) and (S,G) entries.
Syntax
ipv6 mld
no ipv6 mld
Default MLD is disabled by default.
Mode Interface Configuration for a specified VLAN interface or a range of VLAN
interfaces.
Usage 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.
Example
awplus# configure terminal
awplus(config)# ipv6 forwarding
awplus(config)# ipv6 multicast-routing
awplus(config)# interface vlan1
awplus(config-if)# ipv6 enable
awplus(config-if)# ipv6 mld
