Parameters
dscp-value: Sets the DSCP value for DHCP packets, in the range of 0 to 63.
Usage guidelines
The DSCP value is carried in the Traffic class field of a DHCPv6 packet. It specifies the priority level of the
packet and affects the transmission priority of the packet. A bigger DSCP value represents a higher
priority.
Examples
# Set the DSCP value for DHCPv6 packets sent by the DHCPv6 client to 30.
