Use to configure paths over channelized SONET and SDH interfaces.
Specify the correct identifier for the type of interface. See Interface Types and Specifiers
in JunosE Command Reference Guide for details of the syntax.
Example for a cOC3/STM1 interface
host1(config-controller)#path 2 oc1
Example for a cOC12/STM4 interface in SONET mode
host1(config-controller)#path 2 oc1 1/2
Example for a cOC12/STM4 interface in SDH mode
host1(config-controller)#path 2 stm1 2
Use the no version to delete a SONET or SDH path.
See path.
Use to assign a text description or an alias to a channelized SONET path.
You can use this command to help you identify the interface and keep track of interface
connections.
The description or alias can be a maximum of 64 characters.
Example
host1(config-controll)#path 2 description westford
Use the no version to remove the description.
See path description.
Use to overwrite the automatic setting for the path signal label (C2) byte.
By default, the value of the C2 byte for the path is determined by the layers configured
above the SONET/SDH interface and set automatically. The E Series router sets this
default value in accordance with RFC 2558. (See "References" on page 113.)
CAUTION: Use this command only if you know that the automatic setting
does not match the setting on the remote device. Otherwise, the remote
device might send an unexpected value, and the router might lose data.
Example
host1(config-controll)#path 2 overhead c2 20
Use the no version to restore the default setting, in which the value of the C2 byte is
determined by the layers configured above the SONET/SDH interface.
See path overhead c2.
