Applicable Firmware Revision

This guide is applicable to ROS™ software revision v3.5.x.

Firmware/User Guide Version Numbering System

ROS has a three-digit version numbering system of the form X.Y.Z where each digit is a number starting from zero. The 'X.Y' digits represent the functional version of ROS whereas the 'Z' digit represents firmware patches. The 'X' digit is incremented for major functional updates of the product. The 'Y' digit is incremented for minor functional updates of the product. The 'Z' digit is incremented for bug fixes, cosmetic enhancements and other minor issues.

User guides follow the same format. In general, a user guide will have the same 'X.Y' digits as the firmware to which it corresponds.

It is RuggedCom's policy to provide Web access to only the latest 'patch' release for a version of firmware. If you decide that an upgrade is merited, then getting all the fixes only makes sense. It is for this reason that release notes are created detailing all patches for a given functional version.

1.1The ROS™ User Interface

1.1.1 Using the RS232 Port to Access the User Interface

Attach a terminal (or PC running terminal emulation software) to the RS232 port. The terminal should be configured for 8 bits, no parity operation at 57.6 Kbps. Hardware and software flow control must be disabled. Select a terminal type of VT100.

Once the terminal is connected, pressing any key on the keyboard will prompt for the username and password to be entered.

The switch is shipped with a default administrator username “admin” and password “admin”. Once successfully logged in, the user will be presented with the main menu.

RS400

1.1.2 The Structure of the User Interface

The user interface is organized as a series of menus with an escape to a command line interface (CLI) shell. Each menu screen presents the switch name (as proved by the System Identification parameter), Menu Title, Access Level, Alarms indicator, Sub-Menus and Command Bar.

Sub-menus are entered by selecting the desired menu with the arrow keys and pressing the enter key. Pressing the escape key ascends to the parent menu.

Figure 1: Main Menu With Screen Elements Identified

The command bar offers a list of commands that apply to the currently displayed menu. These commands include:

•<CTRL> Z to display help on the current command or data item

•<CTRL> S to switch to the CLI shell

•<CTRL> U/D to jump to next/previous page of a status display

The main menu also provides a <CTRL> X command, which will terminate the session. This type of menu is accessible via serial consol, telnet session and SSH session.

1.1.3 Making Configuration Changes

When changing a data item the user selects the data item by the cursor keys and then pressing the enter key. The cursor will change position to allow editing of the data item.

ROS™ v3.5

16

RS400

Administration

Typing a new value after pressing enter always erases the old parameter value. The left and right cursor keys can be used to position the edit point without erasing the old parameter value. The up and down cursor keys can be used to cycle through the next higher and lower values for the parameter.

After the parameter has been edited, press enter again to change other parameters. When all desired parameters have been modified, press <CTRL> A to apply changes. The switch will automatically prompt you to save changes when you leave a menu in which changes have been made.

Some menus will require you to press <CTRL> I to insert a new record of information and <CTRL> L to delete a record.

1.1.4 Updates Occur In Real Time

All configuration and display menus present the values at the current instant, automatically updating if changed from other user interface sessions or SNMP. All statistics menus will display changes to statistics as they occur.

1.1.5 Alarm Indications Are Provided

Alarms are events for which the user is notified through the Diagnostics submenu. All configuration and display menus present an indication of the number of alarms (in the upper right hand corner of the screen) as they occur, automatically updating as alarms are posted and cleared.

1.1.6 The CLI Shell

The user interface provides a shell for operations that are more easily performed at the command line. You may switch back and forth from the menu system and shell by pressing <CTRL> S. For more information on the capabilities of the shell see the approapriate chapter of this guide.

1.2 The ROS™ Secure Shell Server

1.2.1 Using a Secure Shell to Access the User Interface

SSH (Secure Shell) is a network protocol which provides a replacement for insecure remote login and command execution facilities, such as telnet and remote shell. SSH encrypts traffic in both directions, preventing traffic sniffing and password theft.

SSH protocol version 2 is implemented in ROS. The authentication method is keyboard interactive password authentication. User name will not be verified in order to grant access to SSH server. The passwords to be used for login are configured in Password Table and user’s privileges are the same as for user logged in via the console port.

1.2.2 Using a Secure Shell to Transfer Files

ROS implements SFTP protocol over SSH to transfer files in secure manner. The file system is created in one directory only. Also, all the files are created in the system at startup time and can not be deleted, created, renamed. Files can be downloaded (upgraded) and uploaded (to be analyzed outside of the unit).

The implemented commands are: dir – a file directory

get – upload from the switch and download to PC put – upload from PC and download to PC

1.3 The ROS™ Web Server Interface

1.3.1 Using a Web Browser to Access the Web Interface

A web browser uses a secure communications method called Secure Socket Layer (SSL) to encrypt traffic exchanged with its clients. Web server guarantees that communications with the client is kept private. If client requires access via unsecure http port, it will be rerouted to the secure port. The access via SSL will be granted any client that provides the correct password.

Your browser may complain about SSL Certificate that Web server issues. It happens because the certificate that comes with the Web server is not issued by a recognized certificate authority. However, network traffic is still encrypted.

Start a web browser session and open a connection to the switch by entering a URL that specifies its hostname or IP address (e.g. http://179.1.0.45). Once the switch is contacted, start the login process by clicking on the “Login” link. The resulting page should be similar to that presented below:

ROS™ v3.5

Figure 2: Log in to The Device with a Web Browser

Enter the “admin” user name and the appropriate password for the admin user, and then click on the “LogIn” button. The switch is shipped with a default administrator password of “admin”. Once successfully logged in, the user will be presented with the main menu.

If the user wants to hide device information from the login screen, the ‘Login Banner’ option in the System Identification menu must be set to ‘secure’.

1.3.2 The Structure of the Web Interface

The user interface is organized as a series of linked web pages. The main menu provides the links and allows them to be expanded to display lower level pages for a particular configuration system.

Figure 4: Main Menu via Web Server Interface

Each web page presents the switch name (as proved by the System Identification parameter), Menu Title link and user’s access name or Alarms link if any alarms are reported.

The Menu title link takes you to a page that provides help for the configuration parameters provided by that page.

Alarms are events for which the user is notified by following the Alarms link (these alarms may also be viewed and cleared through the Diagnostics submenu). All configuration and display menus present an indication of the number of alarms (in the upper right hand corner of the screen) as they occur, automatically updating as alarms are posted and cleared.

1.3.3 Making Configuration Changes

When changing a data item the user selects the data item by selecting the field to edit with the mouse, entering a new value and clicking on the apply field. More than one parameter may be modified at a time.

1.5 IP Interfaces

These parameters provide the ability to configure IP connection parameters such as address, network, and mask.

The user can configure an IP Interface for each subnet (VLAN). One of the interfaces is configured as management interface. IP services: TFTP server, SNMP server, Telnet server, SSH server, RSH server, Web server, authentication using RADIUS server, DHCP client, BOOTP client, DHCP relay agent will be available only via management interface. Different IP interfaces MUST NOT overlap, e.g. the subnet mask must be unique.

15 IP interfaces can be configured in the device. In VLAN unaware mode, and in devices that do not act as switches (as RMC30), only one IP interface can be configured.

On non-management interfaces, only static IP addresses can be assigned.

On management interface, the user can choose from the following IP Address type: Static, DHCP, BOOTP and Dynamic. Static IP Address type refers to the manual assignment of IP address while DHCP, BOOTP and Dynamic IP Address types refer to the automatic assignment of IP address.

DHCP is widely used in LAN environments to dynamically assign IP addresses from a centralized server, which reduces the overhead of administrating IP addresses.

BOOTP is a subset of the DHCP protocol. ROSTM supports transfer of a BOOTFILE via BOOTP. The BOOTFILE represents any valid ROSTM file such as config.csv. The name of BOOTFILE on the BOOTP server must match the corresponding ROSTM file.

The Dynamic IP Address type refers to a combination of the BOOTP and DHCP protocols. Starting with BOOTP, the system will try BOOTP and DHCP in a round-robin fashion until it will get a response from the corresponding server.

Figure 8: IP Interfaces Form

Note: The IP address and mask configured for management VLAN are not changed when resetting all configuration parameters to defaults and will be assigned to default VLAN ID of 1. Changes to the IP address take effect immediately. All IP connections in place at the time of an address change will be lost.
