CHAPTER 4: OPERATIONS

4. Operations

4.1 Overview

The SCPS and its ports can be easily configured and managed to meet your

requirements for device connection, user authentication, access control, device

session information display and SNMP compliance for use with third-party network

management products. Support for SSH (Secure Shell) access via third-party clients

is also provided.

4.2 Configuring Serial Port Settings

By default, the SCPS ports are configured with the following settings.

Baud rate

9600

Bits per character

Parity

None

Stop bits

Flow control

None

Time-out

minutes

CLI access character

To change serial port settings:

Issue a Port Set command. You may specify settings for one or all ports.

PORT [<

port

>|ALL] SET [BAUD=<

baud_rate

>] [SIZE=<

size

[PARITY=<

parity

>] [STOP=<

stop_bits

>] [FLOW=<

ow_ctrl

[TIMEOUT=<

time-out>

] [SOCKET=<

socket

>] [CHAR=^<

cli_char

[TOGGLE=NONE|DTR]

For more information, see

Port Set command

in Chapter 6.

To display serial port settings:

Issue a Show Port command.

SHOW PORT [<

port

>|ALL]

The display includes configuration information plus transmit, receive and error

counts. When you request information about a single port and a user is currently

accessing that port, the display also includes the username, access rights and other

information about the current session. For more information, see

Show Port

command

in Chapter 6.
