Serial Port

In the WebUI, use the serial port parameters to configure the serial port on the front panel of the appliance.

To enable the serial port:

Note - This is disabled by default.

  1. Go to Device > Advanced Settings and enter "serial" in the search field.

  2. Double-click the Serial port - Enable serial port attribute name.

  3. In the Serial Port window that opens, select the Enable serial port checkbox.

  4. Select the port speed value from the pull-down menu.

    Notes:

    • You can change the port speed using this attribute or the Serial port - port speed attribute.

    • The port speed must match the configuration of the device connected to the console port.

  5. Click Apply.

To disable the serial port:

Clear the Enable serial port checkbox in the Advanced Settings Serial port attribute.

There are two modes for working with this port:

  • Active - The serial data is relayed to a specified telnet server which can now be viewed through this port. Enter the Server TCP port of the telnet server and the IP address of the server. Two different IP server IP addresses can be configured (Primary server and Secondary server).

  • Passive - In this mode, the flow of data is reversed and the appliance connects through the serial port to the console of the connected device. This console is accessible through a telnet connection to a configured port on the appliance. In the Listen on TCP port field, enter the port number.

To configure an implicit rule that allows traffic from any source to this port:

  1. In the WebUI, go to Access Policy > Firewall Policy and click New to create a new rule.

  2. Make sure Implicitly allow traffic to this port is selected.

    If you do not create an implicit rule, you must manually define an access rule in the Firewall Rule Base.

Two appliances, one in Active mode and the other in Passive mode, can allow a client to remotely connect to a console connected to the appliance in passive mode over the internet using a telnet connection.
