R0106-HP MSR Router Series Interface Command Reference(V7)

233
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 frame format to Synchronous Digital Hierarchy (SDH).
sonet: Sets frame format to Synchronous Optical Network (SONET).
Usage guidelines
Inconsistency between the c2 and j1 settings on the sending and receiving ends 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.
Examples
# Set the SDH overhead byte J0 of ATM 2/4/0 to ff.
<Sysname> system-view
[Sysname] interface atm 2/4/0
[Sysname-ATM2/4/0] flag j0 sdh ff
