R3102-R3103-HP 6600/HSR6600 Routers Interface Command Reference

73
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.

Default command level
2: System level
Parameters
dteclk1: Sets the interface clock selection mode to DTE clock option 1.
dteclk2: Sets the interface clock selection mode to DTE clock option 2.
dteclk3: Sets the interface clock selection mode to DTE clock option 3.
dteclk4: Sets the interface clock selection mode to DTE clock option 4.
dteclkauto: Sets the interface clock selection mode to DTE auto-negotiation.
dceclk1: Sets the interface clock selection mode to DCE clock option 1.
dceclk2: Sets the interface clock selection mode to DCE clock option 2.
dceclk3: Sets the interface clock selection mode to DCE clock option 3.
Usage guidelines
In DTE mode, the synchronous serial interface supports the clock { dteclk1 | dteclk2 | dteclk3 | dteclk4
| dteclkauto } command. In DCE mode, the synchronous serial interface supports the clock { dceclk1 |
dceclk2 | dceclk3 } command.
A synchronous serial interface can operate as DCE or DTE.
• As DCE, the interface provides DCEclk clock to the DTE.
• As DTE, the interface accepts the clock provided by the DCE. Because transmitting and receiving
clocks of synchronization devices are independent, the receiving clock of a DTE device can be
