HP MSR2000/3000/4000 Router Series Interface Command Reference

164
Parameters
c2 flag-value: Path signal flag byte, a higher-order path overhead byte used to indicate the multiplex
structure of virtual container (VC) frames and property of payload. It is a hexadecimal number in the
range of 0x00 to 0xFF.
j0 flag-value: Regeneration section trace message, a section overhead byte used to test continuity of the
connection between two interfaces at the section level. If the sdh keyword is configured, the flag-value
argument is a string of 1 to 15 hexadecimal digits. If the sonet keyword is configured, the argument is a
hexadecimal number in the range of 0x00 to 0xFF.
j1 flag-value: Path trace message, a higher-order path overhead byte used to test continuity of the
connection between two interfaces at the path level. If the sdh keyword is configured, the flag-value
argument is a string of 1 to 15 hexadecimal digits. If the sonet keyword is configured, the argument is a
string of 1 to 62 characters.
sdh: Sets framing format to SDH.
sonet: Sets framing format to SONET.
Usage guidelines
Inconsistency between the c2 and j1 settings of the sending POS interface and the receiving POS
interface causes alarms.
The J0 byte can be any character in the network of the same carrier. If two carriers are involved, make
sure that the sending and receiving devices use the same J0 byte at their network borders.
Examples
# Set the SDH overhead byte J0 of interface POS 5/1.
<Sysname> system-view
[Sysname] interface pos 5/1
[Sysname-Pos5/1] flag j0 sdh ff
