DES-7200 Configuration Guide Chapter 4 MLD
Configuration
4-9
exceeded the limit, and no group record will be generated.
This command can be used to configure each interface, and the interface and
global can be configured separately. If exceeding the number limit of interface or
global configuration, the listener messages will be dropped. Run the following
commands:
Command Function
DES-7200(config)# ipv6 mld limit
number
Global configuration of MLD listener
number limit
Please note that different models
provide different limit ranges. Please
identify the default value according to
the capacity indicator of different
models.
DES-7200(config-if) # ipv6 mld limit
number
Interface configuration of MLD listener
number limit
Please note that different models
provide different limit ranges. The
default value is 1024.
DES-7200(config-if) # ipv6 mld limit
number except access-list-name
The key word of Except indicates that
groups covered by ACL will be limited
in number.
Use the no ipv6 mld limit command to restore the relevant configurations to the
default values.
4.2.12 Configure Host-Behavior Multicast Group Joining
Use this command to configure relevant switch interfaces to implement host
behavior and join the corresponding multicast group. In this way, the sub-switches
can initiatively learn the corresponding group information. This configuration can
be used when a listener is required to be assigned to the interface. Use the no
form of this command to cancel the joining operation.
Command Function
DES-7200# config terminal Enter the global configuration mode.
DES-7200 (config)# interface
interface-id
Enter the interface configuration mode.
DES-7200(config-if)# ipv6 mld
join-group group-address
Enable the interface to join host group.
DES-7200 (config-if) # exit Return to the global configuration mode.
Use the no ipv6 mld join-group group-address command to leave the
corresponding multicast group.
Caution
Some of the local link addresses have been reserved for use by the IP layer. If
such addresses are used as the local link address, no group record will be
generated.
4.2.13 Configure Static Multicast Group Joining
Use this command to directly assign a listener to the relevant switch interface
when a listener is required to be assigned to the interface. Use the no form of this
command to cancel the joining operation.
