Defining Code-Point Aliases

A code-point alias is a name you assign to a set of DiffServ code point (DSCP) and DSCP IPv6 bits. When you configure classes and define classifiers, you can refer to the code points by these alias names. You can configure user-defined classifiers in terms of alias names. If the value of an alias changes, it alters the behavior of any classifier that references it.

To configure class-of-service (CoS) code point aliases, you can include the following statements at the [edit class-of-service] hierarchy level of the configuration:

class-of-service {

    code-point-aliases {

        (dscp | dscp-ipv6 | exp | ieee-802.1 | inet-precedence) {

            alias-name bits;

        }

    }

}

This chapter discusses the following topics:

• Default DSCP Mappings
• Defining Aliases for Bits
