R3303-HP 6600/HSR6600 Routers High Availability Command Reference

90
sonet: Sets the framing format to synchronous optical network (SONET).
j0 flag-value: Specifies the regeneration section trace message. If the sdh keyword is configured, the
flag-value argument is a string of 1 to 15 characters. If the sonet keyword is configured, the argument is
a hexadecimal number in the range of 0x00 to 0xFF.
j1 flag-value: Specifies the higher-Order VC-N path trace byte. If the sdh keyword is configured, the
flag-value argument is a string of 1 to 15 characters. If the sonet keyword is configured, the argument is
a string of 1 to 62 characters.
Usage guidelines
Inconsistency between the c2 and j1 settings of the sending and receiving interfaces causes alarms.
The J0 byte can be any character in the network of the same carrier. If networks of two carriers are
involved, however, the sending and receiving devices at network borders must use the same J0 byte.
With the J0 byte, operators can detect and troubleshoot faults in advance or use less time to recover
networks.
Examples
# Set the framing format on interface RPRPOS 2/1/1 to SONET, and set the SONET overhead byte J0
of RPRPOS 2/1/1 interface to 0xFF.
<Sysname> system-view
[Sysname] interface rprpos 2/1/1
[Sysname-RPRPOS2/1/1] frame-format sonet
[Sysname-RPRPOS2/1/1] flag j0 sonet ff
flag j1 ignore
Use flag j1 ignore to ignore CRC of the J1 byte.
Use undo flag j1 ignore to restore the default.
Syntax
flag j1 ignore
undo flag j1 ignore
Default
CRC is performed for the J1 byte.
