Parameters
flag-value: Specifies a C2 byte value, a hexadecimal number in the range of 0x00 to 0xFF.
Usage guidelines
The C2 byte is a higher-order path overhead byte. It indicates the multiplex structure of virtual container
(VC) frames and the property of payload.
The C2 byte must be the same at both ends of a link.
Examples
# Set the C2 byte to 0x01 on POS 2/2/0.

Parameters
flag-value: Specifies the J0 byte. It must be a string of 1 to 15 characters for SDH, and a hexadecimal
number in the range of 0x00 to 0xFF for SONET.
sdh: Specifies the SDH framing format.
sonet: Specifies the SONET framing format.
Usage guidelines
J0 byte is a section overhead byte. SDH and SONET use this byte to test continuity of the connection
between two interfaces at the section level.
The J0 byte can be different on devices of the same service provider. On the interfaces between two
service providers, the J0 byte must be the same.
Examples
# Set the J0 byte to 0xFF for SDH on POS 2/2/0.
