Chapter 3: Operations

Overview

The CCM and its ports may be easily configured and managed to meet your requirements for device connection, user authentication, access control, power status monitoring, port history information display and SNMP compliance for use with third-party network management products.

Configuring Serial Port Settings

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

Target device

Console

Name

xx-xx-xx Pn (last 3 octets of MAC address

 

plus the port number)

Baud rate

9600

Bits per character

8

Parity

None

Stop bits

1

Flow control

None

Time-out

15 minutes

CLI access character

Use Server CLI setting (^D)

Power

None

Most of these settings are standard serial port operating characteristics.

The CLI access character parameter specifies how you access the CLI. For more information, see CLI mode in this chapter.

The Power parameter instructs the CCM to monitor the state of a specified control signal. Signal transitions may be configured to trigger SNMP alerts. The parameter value indicates an inbound control signal (CTS, DCD or DSR) and the state of that signal (low or high). When the defined signal is true, the CCM interprets it as a power on condition for the attached device; when the signal is false, a power off condition for the device is assumed. The signal specified for flow control cannot be used for power control, and vice versa.

To configure serial console port settings:

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