Physical interface-based classifiers are supported at the [edit class-of-service interfaces interfaces-name] hierarchy level. EXP bits are located in each MPLS label and used to encode the CoS value of a packet as it traverses an LSP. To configure global EXP bits, include the exp statement at the [edit class-of-service system-defaults classifiers] hierarchy level.

To configure CoS on ACX Series routers:

Configure the class of service.
```
[edit]
user@host# edit class-of-service 
```

Configure the rewrite rules.

content_copy zoom_out_map
[edit class-of-service]
user@host# edit rewrite-rules (dscp | inet-precedence) rewrite-name
user@host# edit forwarding-class class-name
user@host# set loss-priority low class-name code-points (alias | bits)

Configure behavior aggregate classifiers for DiffServ CoS.

content_copy zoom_out_map
[edit class-of-service]
user@host# edit classifiers (dscp | inet-precedence) classifier-name
user@host# edit forwarding-classes class-name
user@host# set loss-priority class-name code-points (alias | bits)

Configure expedited forwarding class classifiers.

content_copy zoom_out_map
[edit class-of-service classifiers]
user@host# edit forwarding-classes class-name
user@host# set loss-priority class-name code-points (alias | bits)

Define the forwarding-class mappings.

content_copy zoom_out_map
[edit class-of-service]
user@host# edit forwarding-classes class queue-number queue-number

Configure network control forwarding class classifiers.

content_copy zoom_out_map
[edit class-of-service] 
user@host# edit forwarding-class class-name
user@host# set loss-priority low class-name code-points (alias | bits)

Apply the rewrite rules and classifiers to the interfaces.

content_copy zoom_out_map
[edit class-of-service interface interface-name unit unit-number] 
user@host# set rewrite-rule (dscp | inet-precedence ) (rewrite-name| default)
user@host# set classifiers (dscp | inet-precedence ) classifier-name | default)

Set the global system default.

content_copy zoom_out_map
[edit ] 
user@host# edit class-of-service system-defaults classifiers exp classifier-name
