Configuring the active clock edge
Depending on the system configurations—i.e. when using long cables, with certain modem types or data
rates—synchronization problems may occur on the serial port. In these cases, it may be necessary to configure
the clock edge on which data is transmitted.
This procedure describes how to set the active clock edge of the serial interface
Mode: Port serial
Step

on-edge positive
node (prt-ser)[ slot/port ]# transmit-data-
2
on-edge negative
Example: Configuring the active clock edge
The following example enables to send data on the negative edge on slot 0 and port 0. Check that Transmit
Clock is set to inverted in the command output of
node(cfg)#port serial 0 0
node(prt-ser)[0/0]#transmit-data-on-edge negative
node(prt-ser)[0/0]#show port serial

Configuring the baudrate
A DCE interface has to provide the signal clocks. The desired baudrate can be configured.
Note
Only available on certain devices.
This procedure describes how to set the baudrate for the serial interface.
