#### Syntax

tunnel mpls diff-serv phb-id { private privateId | standard standardId } [ exp-bits expBits ]

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.
