Rewrite Rule Configuration

Global Classifier Association with Interfaces

Hierarchy Level


Define the EXP code point mapping that is applied to MPLS packets. EXP classifiers are not applied to any traffic except MPLS traffic. EXP classifiers are applied only to interfaces that are configured as family mpls (for example, set interfaces xe-0/0/35 unit 0 family mpls.)

There are no default EXP classifiers. You can configure up to 64 EXP classifiers.

On QFX10000 switches, you can configure and apply EXP classifiers to interfaces in the same way that you configure and apply DSCP, DSCP IPv6, and IEEE classifiers to interfaces. Different interfaces can have different EXP classifiers. QFX10000 switches do not support global EXP classifiers.

However, QFX5100, EX4600, QFX3500, and QFX3600 switches, and on QFabric systems, the switch uses only one EXP classifier as a global MPLS classifier on all interfaces. You specify the global EXP classifier in the [edit class-of-service system-defaults] hierarchy.
