Setting the DSCP value for MLD messages
IPv6 uses an eight-bit Traffic class field (called ToS in IPv4) to identify type of service for IP packets. As
defined in RFC 24724, the first six bits contains the DSCP priority for prioritizing traffic in the network and
the last two bits are reserved.
T
his configuration applies to only the MLD messages that the local switch generates
when the switch or
its port acts as a member host,
rather than those forwarded ones.
To set the DSCP value for MLD messages:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter MLD-snooping view.
mld-snooping
N/A
3.
Set the DSCP value for MLD
messages.
dscp
dscp-value
By default, the DSCP value in MLD
messages is 48.

MLD snooping–enabled VLAN, but
not in a VLAN with MLD enabled
on its VLAN interface.
This command cannot remove the
static group entries of MLD
snooping groups.
