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 confi gure serial console port settings:
Issue a Port Set command. You may specify settings for one or all ports.
