Defining CoS Code-Point Aliases (CLI Procedure)

You can use code-point aliases to streamline the process of configuring CoS features on your EX Series switch. A code-point alias assigns a name to a pattern of code-point bits. You can use this name instead of the bit pattern when you configure other CoS components such as classifiers, drop-profile maps, and rewrite rules.

You can configure code-point aliases for the following CoS marker types:

  • DSCP—Handles incoming IPv4 packets.
  • IEEE 802.1p—Handles Layer 2 CoS.
  • Inet precedence—Handles incoming IPv4 packets. IP precedence mapping requires only the higher order three bits of the DSCP field.

To configure a code-point alias for a specified CoS marker type (dscp), assign an alias (my1) to the code-point (110001):

[edit class-of-service code-point-aliases]
user@switch# set dscp my1 110001
