R3303-HP HSR6800 Routers Interface Command Reference

66
Default command level
2: System level
Parameters
baudrate: Baud rate (in bps) to be set for a serial interface.
Usage guidelines
The following are the baud rates available with synchronous serial interfaces:
1,200 bps, 2,400 bps, 4,800 bps, 9,600 bps, 19,200 bps, 38,400 bps, 56,000 bps, 57,600 bps,
64,000 bps, 72,000 bps, 115,200 bps, 128,000 bps, 192,000 bps, 256,000 bps, 384,000 bps,
512,000 bps, 1,024,000 bps, 2,048,000 bps, and 4,096,000 bps.
The baud rate range available with synchronous serial interfaces depends on the applied physical
electric specifications.
• For V.24 DTE/DCE, the baud rate available is in the range of 1,200 bps to 64,000 bps.
• For V.35 DCE/DCE, X.21 DTE/DCE, EIA/TIA-449 DTE/DCE, and EIA-530 DTE/DCE, the available
baud rate is in the range of 1,200 bps to 4,096,000 bps.
Take the physical electric specifications of the cable into consideration when setting the baud rate for a
serial interface.
The baud rate adopted by a DCE-DTE pair is determined by the DCE.
Examples
# Set the baud rate of synchronous serial interface 2/0/0 at DCE side to 115200 bps.
<Sysname> system-view
[Sysname] interface serial 2/0/0
[Sysname-Serial2/0/0] baudrate 115200
clock
Use clock to set clock selection mode for the synchronous serial interface.
Use undo clock to restore the default.
Syntax
clock { dteclk1 | dteclk2 | dteclk3 | dteclk4 | dteclkauto }
clock { dceclk1 | dceclk2 | dceclk3 }
undo clock
Default
The DTE-side clock on a synchronous serial interface dteclk1 and the DCE-side clock is dceclk1.
