#### Syntax

no tunnel mpls diff-serv phb-id { private privateId | standard standardId }

#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

Specifies the PHB supported by a signaled tunnel.

For E-LSPs, this command also maps the PHB to the specified EXP bits bitValue. You can repeat the command for up to eight PHB mappings.

For L-LSPs, the exp-bits keyword is not used. If you repeat the command, the most recent command overwrites the previous command.

The no version removes the mapping association.

#### Options

- privateId—Number, in the range 0–4095, designating the private PHB identifier
- standardId—Number, in the range 0–63, designating the standard identifier using the DSCP bits
