# path

#### Syntax

path pathChannel [ pathSpeed [ pathHierarchy ] ]

no path pathChannel

#### Release Information

Command introduced before JUNOSe Release 7.1.0.

#### Description

Configures paths over channelized SONET and SDH interfaces. The no version deletes a path.

| Note: Although the path speed appears to be optional in the software, you must specify a value.

#### Options

- pathChannel—Number, in the range 1–2147483648, that identifies the STS-1 or STM-0 line
- pathSpeed—Speed of the path
  - oc1, oc3, or oc12 for SONET—Only oc1 is available for cOC3/STM1 interfaces
  - stm0, stm1, or stm4 for SDH—Only stm0 or stm1 is available for cOC3/STM1 interfaces
- pathHierarchy—Identifier that defines the structure of the path
  - If you specify a path speed that matches the speed of the module (for example, a path speed of stm1 for a cOC3/STM1 interface), do not specify an identifier.
  - If you specify a speed of oc1 or stm0 for a cOC3/STM1 interface, the identifier is a number, in the range 1–3, that represents either the STS-1 within the STS-3 or the STM-0 within the STM-1.
  - If you specify a speed of stm1 for a cOC12/STM4 interface, the identifier is a number, in the range 1–4, that represents the STM-1 within the STM-4.
  - If you specify a speed of oc1 or stm0 for a cOC12/STM4 interface, the identifier is of the form X/Y. X is a number, in the range 1–4, that represents either the STS-3 within the STS-12 or the STM-1 within the STM-4; Y is a number, in the range 1–3, that represents either the STS-1 within the STS-3 or the STM-0 within the STM-1.
