R3303-HP HSR6800 Routers Interface Command Reference

within the subrate range available in the specified DSU mode. This calculated precise subrate is the
one actually applied to the hardware circuit.
• You can use the display interface serial interface-number:0 command to display the DSU mode,
configured subrate, actual rate, and baud rate of an E3 interface. The actual rate of the E3 interface
is the pure data bandwidth excluding the bandwidth for overhead bytes. The baud rate of the E3
interface, 34368 kbps, is the actual rate of the E3 circuit, including the bandwidth for the overhead
bytes.
Examples
# Configure E3 channel 1 on interface CPOS 2/0/0 to operate in DSU mode 1 and set its subrate to
500 kbps.

flag
Use flag to set the overhead bytes of SONET/SDH frames.
Use undo flag to restore the default.
Syntax
flag { c2 path-number c2-value | s1 s1-value | s1s0 path-number s1s0-value }
undo flag { c2 path-number | s1 | s1s0 path-number }
flag { j0 | j1 path-number } { sdh | sonet } flag-value
undo flag { j0 | j1 path-number } { sdh | sonet }

Parameters
j0 flag-value: Specifies the regenerator section trace message, which is a section overhead byte used to
detect the continuity of the connection between two interfaces at the section layer. With SDH frames,
flag-value is a string of 1 to 15 characters; with SONET frames, flag-value is in the range of 0x00 to 0xFF.
j1 path-number: Specifies the path trace message, which is a higher-order path overhead byte used to
detect the continuity of the connection between two interfaces at the path layer. With SDH frames,
flag-value is a string of 1 to 15 characters; with SONET frames, flag-value is a string of 1 to 62
characters.
sdh: Specifies the framing format as Synchronous Digital Hierarchy (SDH).
sonet: Specifies the framing format as Synchronous Optical Network (SONET).
c2 path-number c2-value: The path-number argument is the number of a path. The c2-value argument
specifies the path signal label byte; it is in the range of 0x00 to 0xFF and defaults to 0x02.
