Configuring the EN-4000’s Serial
Ports
A
module containing two serial ports is installed in an expansion port on the
front of the EN-4000. This document discusses configuration of the EN-4000’s
serial ports.
Also see Configuring Chassis Ports in the EN-4000.
7.1
Connecting to the EN-4000
Connect a management terminal to the EN-4000, and log into the management
system. (For details, see Using the EN-4000’s Management System, in the document
Configuring General Settings for the EN-4000.)

Configuring a Serial Port
On the EN-4000 Management System, select the Network tab.
❖ The Network Interfaces Screen is displayed (Figure 7-1).

❖ The Serial Port Configuration Screen is displayed (Figure 7-2).
Figure 7-2. Serial Port Configuration Screen
The default configuration for the dual serial-port module includes the
following. (Port names—for example, ttyACM10—may differ in your set-up.)
• ttyACM10: The Asynchronous Encapsulation protocol is the default
configuration for one of the physical serial ports. This protocol sends and
receives Async Encaps transmissions to and from a remote device.
• ttyGRE5: This virtual port uses general route encapsulation (GRE) to send
and receive Frame Relay transmissions. (GRE uses the Internet Protocol,
IP.)
• ttyACM11: The Telnet Terminal protocol is the default configuration on
one of the physical serial ports.
The port configurations named ttyACM10 and ttyACM11 refer to discrete
serial ports; each serves only one physical port. The port configuration
named ttyGRE5 is a virtual port and can serve both physical serial ports.
Additional virtual ports can be configured.

If you wish to customize a port configuration, select that row’s Edit button.
For example, select the edit button in the row for ttyACM10.
❖ The Serial Port Configuration Detail Screen is displayed (Figure 7-3).

On the Serial Port Configuration Detail Screen, configure the following near
the top of the screen:
• Port Name: At the direction of your network administrator, you may
rename the port to something more meaningful in your network.
• Protocol: You may change the protocol that the port uses. The choices
are:
◆
Telnet Terminal
◆
Frame Relay (Synchronous Mode)
◆
Frame Relay (IP)
◆
Asynchronous Encapsulation
❖ The protocol selection determines the fields that appear on the rest of the
screen.

See one of the following, as appropriate:
• Step 6: Serial Port Configuration for Telnet Terminal
• Step 7: Serial Port Configuration for Frame Relay (Synchronous Mode)
• Step 8: Serial Port Configuration for Frame Relay over IP
