The dhcp dscp-outbound command sets a differentiated services code point (DSCP) value for DHCP reply messages.
The undo dhcp dscp-outbound command deletes the DSCP value in DHCP reply messages.
By default, no DSCP value is set for DHCP reply messages.

Usage Scenario
On an IPTV network, a user device sends DHCP Offer messages with priority 0 to a set top box (STB) for registration. The STB does not identify messages with priority 0 and fails to assign an IP address to the user. The dhcp dscp-outbound command is used in this scenario.
Configuration Impact
The dhcp dscp-outbound command enables a DHCP broadband access server, DHCP Server, or relay agent to send DHCP reply messages carrying non-zero priorities so that the devices can receive replies.
