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.

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

The display for Show Port Names 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. The display for Show Port Groups includes the port number and port group name, if assigned.

For more information, see Show Port command on page 77.

Connecting to Serial Devices

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

You may use the session sharing feature to permit multiple concurrent connections to a port. See Session sharing on page 23 for more information.

Connecting to devices using Telnet

Each CCM serial port is directly addressable through a unique TCP port that provides a connection to the attached serial device.

Plain text (non-encrypted) Telnet connections are enabled by default. For information about enabling both plain text Telnet and SSH connections, Enabling plain text Telnet and SSH connections on page 23 and Server Security command on page 70.

You may access the CCM appliance and its ports using the AVWorks software Telnet client or third party Telnet client applications. Third party Telnet applications may be used in combination with AVWorks software or standalone.

AVWorks software Telnet client

Each CCM appliance ships with the AVWorks cross-platform management application. AVWorks software provides a convenient way to select a CCM appliance or an attached device and launch a Telnet session to manage it.

AVWorks software includes a built-in Serial Console Viewer Telnet application that offers several features not found in other Telnet clients. For maximum flexibility, AVWorks software allows you to associate a unique Telnet client with each CCM port. AVWorks software also provides built-in support for SSH2.

You may specify the built-in Telnet client or a third party Telnet client. For more information, see the AVWorks Installer/User Guide.
