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

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

Standalone third-party Telnet clients

You may use third-party Telnet clients to access the CCM directly without AVWorks management software.

Connecting to devices from the serial CLI port

By factory default, port 1 of the CCM is configured with the serial CLI, which prohibits the use of port 1 with an attached serial device. You may configure the CLI on a different port, but only one port may be configured as the serial CLI port at one time. For example, when you enable the CLI interface on port n, and it is already active on port p, then the CLI will automatically be disabled on port p.

You may connect to one serial device at a time through the serial CLI port using a local terminal or a local PC using a terminal emulation program. If you connect an external modem to the serial CLI port, you may also access devices through a remote terminal or PC that can dial into the CCM external modem. For information about modem connections, see Configuring and using dial-in connections in this chapter and Server CLI command in Chapter 5.

To conﬁgure a port for the serial CLI:

1.Issue a Server CLI command, using the Port parameter to specify the CLI port and the Type parameter to specify the terminal type.

SERVER CLI PORT=<port> TYPE=<type>

2.To disable the CLI that was previously conﬁgured on a port, issue a Server CLI command, indicating Type=Off.

For more information, see Server CLI command in Chapter 5.

To display CLI port information:

Issue a Show Server CLI command.

SHOW SERVER CLI

The display includes the CLI port number and terminal type, plus the CLI access character. For more information, see Show Server CLI command in Chapter 5.
