# Run the display mld interface command to view the configuration and running status
of MLD on the switch interface. The display information is as follows:
<SwitchA> display mld interface vlanif 10
Interface information
Vlanif10(FE80::200:5EFF:FE66:5100):
MLD is enabled
Current MLD version is 1
MLD state: up
MLD group policy: none
MLD limit: 30
Value of query interval for MLD (negotiated): 125 s
Value of query interval for MLD (configured): 125 s
Value of other querier timeout for MLD: 0 s
Value of maximum query response time for MLD: 10 s
Querier for MLD: FE80::200:5EFF:FE66:5100 (this switch)

10.8 Maintaining MLD
Maintaining MLD involves resetting MLD group information, and monitoring MLD running
status.
10.8.1 Clearing Information about MLD Groups
After you confirm to clear the statistics on MLD groups, use the reset commands in the user
view. The receiver cannot receive multicast information normally if the MLD group that the
interface dynamically joins is deleted. Therefore, confirm the action before you use the reset
commands.
Context
CAUTION
The MLD groups that an interface dynamically joins are deleted after you run the reset mld
group or the reset mld group ssm-mapping command. Receivers may not receive multicast
information normally. So, confirm the action before you use the command.
Procedure
l Run the reset mld explicit-tracking { all | interface interface-type interface-number
[ host ipv6-host-address [ group ipv6-group-address [ source ipv6-source-address ] ] ] }
command in the user view to clear the hosts that join a multicast group through MLD on
an interface.
