Ways to Configure the SERIMUX

This section discusses the three ways to configure the SERIMUX, web interface, configuration menu, and command line interface.

Web Interface

The web interface provides an easy way to configure the SERIMUX. The root user and system administrator can configure all
features from it. Port administrators can configure ports, including port clustering, but cannot modify system settings. Users cannot
use the web interface for configuration. To access the web interface, enter the SERIMUX IP address or host name in a
browser’s URL window. The default IP address is 192.168.161.5. The following page is displayed after log in.

Note: The SERIMUX web interface features HTTPS for secure access

NTI

Figure 1- SERIMUX SECURE WEB Interface- Main menu
Configuration Menu

The root user and system administrator have full access to the configuration menu from a Telnet session or a serial connection
through the console port. Functionality is similar to the web interface, with the exception of custom menus, which can be created
only from the web interface. The configuration menu is presented to system administrators automatically. Root users access it by
entering the command configmenu. Port administrators can access this menu but can modify serial port configuration only.
Users cannot access this menu.

Figure 2- SERIMUX-SECURE Telnet Session- Configuration menu
Command Line Interface

The command line interface can be accessed from a Telnet session or from the console port. The root user al ways has access to
this interface. The system administrator can be granted read-only permission as well. No other users can access the command
line interface.

Ways of Accessing the SERIMUX: Overview

There are four ways to access the SERIMUX including:

• Web Interface

• Port Access Menu

• Direct Port Access

• Custom Menus

Web Interface Access Menu

The web interface menu provides easy and convenient access to ports. All users can acc ess the men u b y enter ing the SERIMUX
IP address or host name in a web browser’s URL window.

To access a port from the web interface, do the following:

1. Access the web interface.

2. Choose Serial port > Connection.

3. Choose a port by clicking in the appropriate icon.
A Java applet or Telnet window opens with a login prompt.

Figure 3- WEB Interface- Port login screen
Port Access Menu

The Port Access Menu provides access to ports. It is accessible to all users through the web interface, Telnet and SSH sessions,
and remote modem access. The information that follows shows how to access this menu.

Access Type Permissions Procedure

Web interface Any user can use

This method.

Telnet Any user can use

This method.

Command line Root From the command line, issue the portaccessmenu command.

1. Access the web interface.

2. Choose Serial port > Connection > Port access menu connection.

3. Log in.

1. Telnet to the SERIMUX specifying its IP address and port 7000.
Example: Telnet 192.168.15.7 7000

2. Log in.

Example: portaccessmenu

4

Direct Port Access

Users can connect directly to a properly configured port through a Telnet or SSH session. Configuration requirements includ e
setting the Host Mode to Console Server Mode and the Protocol to either Telnet or SSH. Ports, by default, are set to Console
Server Mode and Telnet. Use the information that follows to make a Telnet or SSH connection to a port:

Type Command Syntax Example Connection to Port 3

telnet ip-address tcp-port

Telnet

where ip-address is the SERIMUX’s IP

telnet 192.168.15.7 7003

address and tcp-port is the Listening
TCP port for a port
ssh user-name@ ip-address tcp-port

SSH

where user-name is a user’s name,
ipaddress is the SERIMUX’s IP address

ssh admin@ 192.168.15.7 7003

and tcp-port is the Listening TCP port for
a port

Note: The example assumes that the Listening TCP port is 7003, the default for port 3.

Custom Menus

Custom menus are created by either root or the system administrator to limit a user’s access to specific ports. For more
information, see "Making Custom Menus" on page 36.

Saving and Applying Changes

In the web interface, the user can save and apply configuration changes in two ways. With the one-step method, choose “Save &
apply” and changes are saved and applied enabling them to take effect immediately. With the two-step method, choose “Save to
flash,” which immediately saves changes but the changes do not take effect until choosing "Apply changes.” This might be more
efficiently used if multiple changes are being made. The following topics describe how to do each of these oper ations.

One Step: Save and Apply Changes

To save and apply changes immediately, choose the Save & apply button.

Two-Step: Save to Flash and then Apply Changes

To save multiple changes but apply changes once, do the following:

1. Choose the Save to flash button after each configuration change.

2. When finished changing the configuration, choose the Apply changes link, which is located on the main menu.

Getting Started

Getting Started

Introduction

This chapter covers basic configuration topics. Included is information on assigning IP settings, enabling secure access with the
web interface, accessing the unit through SSH, and adding and removing users.

Note: Initial setup is described in the Quick Start Guide included with the product packaging.

Assigning IP Settings from the Console Port

To use the console port to assign IP settings, do the following:

1. Connect the console port on the rear panel of the SERIMUX to a serial port on a workstation using the Ethernet console cable
and DB-9 adapter packaged with the SERIMUX. (See Fig. 4) The default IP address is 192.168.161.5.
