Authentication Complete
Connected to Port: ...
If the authentication method is configured as None, you may Telnet and connect to a serial device
without entering credentials; however, credentials are always required when connecting to the
CPS CLI.
Data entered at the Telnet client is written to the attached serial device. Any data received by the
CPS appliance from the serial device is output to your Telnet client.
Connecting to devices from the serial CLI port
By factory default, port 1 of the CPS network appliance 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, if you
attempt to 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 external
modem. For information about modem connections, see Connecting to devices using SSH on
page 16, Configuring and using dial-in connections on page 15 and Server CLI command on
page 51.
For more information about serial CLI port connections, see Authentication of serial CLI port
sessions on page 26 and Preemption on page 21.
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 on page 51.
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 on page 65.
To connect to a device from the serial CLI port:
1. Issue a Server CLI command, using the Connect parameter to enable the use of the Connect
command from the serial CLI port.
SERVER CLI CONNECT=ON
