Usage Guidelines The DSCP field in an IP packet enables different levels of service to be assigned to network traffic.

Levels of service are assigned by marking each packet on the network with a DSCP code. DSCP is the

combination of IP Precedence and Type of Service (ToS) fields. For more information, see RFC 2474.

A DSCP value is assigned in an application definition or an application policy map and applies to all

traffic associated with the application or policy map. If a DSCP value is not assigned or defined, the

default DSCP value is applied to traffic. The global default DSCP value is copy, which copies the DSCP

value from the incoming packet and uses it for the outgoing packet.

Table 3-119 lists the valid DSCP marking values that you can specify.

set-dscp dscp-marking Specifies the DSCP marking value, as shown in Table 3-119.
