| MLD Snooping Commands
– 501 –
COMMAND USAGE
◆ When MLD proxy is enabled, the switch exchanges MLD messages with
the router on its upstream interface, and performs the host portion of
the MLD task on the upstream interface as follows:
■
When queried, it sends multicast listener reports to the group.
■
When a host joins a multicast group to which no other host belongs,
it sends unsolicited multicast listener reports to that group.
■
When the last host in a particular multicast group leaves, it sends
an unsolicited multicast listener done report to the all-routers
address (FF02::2) for MLDv1.
EXAMPLE
MLD>proxy enable
MLD>
mld state This command displays or sets the MLD snooping state for the specified
VLAN.
SYNTAX
mld state [vlan-id] [enable | disable]
vlan-id - VLAN identifier. (Range: 1-4095)
enable - Enables MLD snooping. When enabled, the switch will
monitor network traffic on the indicated VLAN interface to
determine which hosts want to receive multicast traffic.
disable - Disables MLD snooping.
DEFAULT SETTING
Disabled
COMMAND USAGE
When MLD snooping is enabled globally, the per VLAN interface settings for
MLD snooping take precedence. When MLD snooping is disabled globally,
snooping can still be configured per VLAN interface, but the interface
settings will not take effect until snooping is re-enabled globally.
EXAMPLE
MLD>state enable
