Description
Use drop-unknown to enable the function of dropping unknown IPv6 multicast data globally.
Use undo drop-unknown to disable the function of dropping unknown IPv6 multicast data globally.
By default, this function is disabled. That is, unknown IPv6 multicast data is flooded in the VLAN.
This command works only in MLD snooping–enabled VLANs, but not on VLANs with MLD enabled on
their VLAN interfaces.
Related commands: mld-snooping drop-unknown.
Examples
# Enable the device to drop unknown IPv6 multicast data.

Parameters
dscp-value: Specifies the DSCP value for MLD messages, in the range of 0 to 63.
Description
Use dscp to set the DSCP value for MLD messages.

port acts as a member host, rather than those forwarded ones.
