Use to assign a text description or an alias to an unchannelized SONET interface.
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.
Use "show controllers sonet" on page 96 to display the text description.
Example
host1(config-controll)#description boston-sonet-interface
Use the no version to remove the text description or alias.
See description.
Use to assign a text description or an alias to an unchannelized 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 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 81.)
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.
Do not specify a path identifier for unchannelized SONET/SDH interfaces.
Example
host1(config-controll)#path 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.
