Introduction
This chapter provides an overview of the serial port and describes the tasks involved in its configuration
includes the following sections:
•
Serial port configuration task list
•
Configuration tasks

Examples
The V.35 standard is recommended for speeds up to 48 kbps, although in practice it is used successfully at 4
Mbps. The X.21 standard is recommended for data interfaces transmitting at rates up to 2 Mbps and is used
primarily in Europe and Japan.
The synchronous serial interface supports full-duplex operation and allows interconnection to various serial
network interface cards or equipment. Refer to the getting started guide included with your SmartWare for
specific information regarding the connector pinout and the selection of cables to connect with third-party
equipment.
Serial port configuration task list
Perform the tasks in the following sections to configure a synchronous serial interface:
•
Disabling an interface (see
page 169
)
•
Enabling an interface (see
page 170
)
•
Configuring the serial encapsulation type (see
page 171
)
•
Configuring the hardware port protocol (see
page 171
)
•
Configuring the active clock edge (see
page 172
)
•
Configuring the baudrate
Disabling an interface
Before you replace a compact serial cable or attach your SmartNode to other serial equipment, use the
shutdown
command to disable the serial interfaces. This prevents anomalies and hardware faults. When you
shut down an interface, it has the state
CLOSED
in the
show port serial
command display.
Note
Use the
no shutdown
command to enable the serial interface after the con-
figuration procedure.
This procedure describes how to shut down a serial interface
