that port, the display also includes the username, access rights and other information about the current session.

When you request information about a single SPC port, the display includes information configured with the SPC command. A Show Port All command will indicate which ports are SPC ports.

When you request information about port names, the display includes the port numbers and names. If a port’s name has not been changed with a Port Set command, the logical name is displayed.

For more information, see Show Port command on page 62.

Connecting to Serial Devices

The CPS network appliance offers several methods for connecting to attached serial devices: Telnet, serial CLI, PPP and SSH.

Connecting to devices using Telnet

Each CPS serial port is directly addressable through a unique TCP port that provides a connection to the attached serial device. You may connect using either SSH or plain text.

DSView management software

The Avocent DSView management software offers an interface to access devices attached to Avocent digital Keyboard, Video and Mouse (KVM) appliances and CPS network appliances. The Telnet client built into the DSView software uses Windows server-based authentication and authentication servers to control access. Third party Telnet clients may also be supported with DSView management software. For more information, see the DSView Installer/User Guide.

Standalone third party Telnet clients

You may use third party Telnet clients to access the CPS appliance directly without DSView management software.

To connect to a device using Telnet:

Type telnet, followed by the CPS IP address and the appropriate TCP port, which by default is 3000 plus the physical port number, in decimal format. (The TCP port number may be changed for any CPS port.)

For example, the following Telnet command connects to the serial device attached to physical port 14 of the CPS network appliance.

telnet 192.168.0.5 3014

If an authentication method other than None has been configured for the CPS appliance, you will be prompted for a username and password. Once authentication completes, your connection is confirmed. When you successfully connect to the serial device, you will see a display similar to the following.
