SONET Controller Commands on the Cisco ASR 9000 Series Router
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
The SONET standards permit or require user access for configuration of some bytes or bits in the SONET
path overhead. Use the overhead command to set the SONET path overhead bytes in the frame header to a
specific standards requirement. Use the no form of this command to remove the setting of the SONET path
overhead bytes from the configuration file and restore the system to its default condition.
Use the c2 keyword to configure the desired C2 byte value in the SONET path overhead.
Use the j1 keyword to configure a user-defined path trace message in the j1 bytes of the SONET path overhead.
For the j1 keyword, use the default message or insert your own message that has a maximum of 62 characters.
If no user-defined message is configured, a default message is automatically generated, containing the router
name, the controller name, its IP address, and the values of the sent and received K1 and K2 bytes in the
SONET line overhead.
Examples
The following example shows how to set the STS SPE C2 byte in the SONET path frame header:
RP/0/RSP0/CPU0:router(config)# controller sonet 0/2/0/2
RP/0/RSP0/CPU0:router(config-sonet)# path
RP/0/RSP0/CPU0:router(config-sonet-path)# overhead c2 0x13
