Product Overview
Basics
The Nimbra series of multi-service switches runs the DTM (Dynamic
synchronous Transfer Mode) network protocol, standardized by ETSI, which is
designed to increase the utilization of optical fibers and minimize the load of
the network nodes. The protocol is also designed to support real-time
broadband traffic, multicasting, and the ability to dynamically adapt to traffic
variations in the network.
DTM combines the simple, non-blocking, real-time traffic capabilities of circuit
switching with the dynamic resource handling of packet switching technology.
This covers a gap in available techniques on the market and meets the demands
of strict quality of service requirements for high-bandwidth communications.
About the Nimbra One
Nimbra One is a modular switch with hot-swap support for one control module
and up to seven interface modules. The backplane provides up to 20 Gbps
switching capacity, with an average non-blocking capacity of 5 Gbps, making it
ideal for all cases of multi service access switching. A Nimbra One can be
equipped with: One Control Module (mandatory in slot 1) and any combination
of trunk and access modules, presented below:
Trunk modules:
4 x DS3/E3 Trunk Module
OC-3/STM-1 Trunk Module (DTM150 Trunk Module)

The User Interface
Overview
The implemented software provides necessary functionality for node
management, such as configuration and monitoring of the units.
Among the functions are:
•Network configuration changes
•Unit handling
•Software diagnostics and upgrade
The majority of the units handling procedures are carried out via a web
browser. The functions are also available via a text-based terminal connection.
Connecting to the units
Communication with the units is done either locally through a terminal
connected directly to the unit, or when the unit is in operation, remotely over
the in-band management network.
Required software
•Terminal software: To utilize the terminal connection via the Serial
Control Port, a standard terminal emulation software (VT100) is required,
e.g. Windows Terminal.
•FTP client: FTP is used to transfer the required configuration files to and
from the unit.
•Web interface: For the web interfaces a standard web-browser able to
handle Java-script and cookies should be used.
Internet Explorer 5.5, Mozilla 1.4 Netscape 7, Firefox 1.0 or later versions
are recommended web browsers.

16 •The User Interface Element Manager User’s Manual Nimbra OneSerie
©2006 Net Insight AB, All rights reserved
Command Line Interface
A CLI (Command Line Interface) is a set of system commands used for
management of the Nimbra nodes via a Terminal or a Telnet software. E.g. the
CLI can be used when connecting to the unit via the Serial Control Port using a
Terminal software, or when connecting via Telnet (TCP/IP) over the Ethernet
Control Port or over the in- management network. Normally the web interface
should be used. The CLI is intended mainly for initial configuration operations.
Web interface
The web interface is the easiest and most straightforward way to communicate
with the units. It is designed to be easy to use, to navigate and to give a good
overview of the configuration status of the unit and the parameters required in
each configuration. All normal monitoring and configuration should be done
using the web interface. The pages of the web interface automatically adapt to
the information to be monitored or configured. Refer to Figure 4.
Figure 4. The web based user interface
•Alarm monitor: Shows the number of alarms indicated and their severity.
•Utility menu: Gives access to the unit’s home and log out pages and it
also gives quick access to the alarms page; refer to chapter Status
monitoring, section Alarms.
•Title bar: In this space the name of the page is displayed.
•Main menu: Here is the entire pages regarding the unit’s configuration
and monitoring accessed. The menu is organized in a tree structure where
the top row shows the main items and submenus are displayed below.
Functions that are not available appear grayed out.
•Links to edit this object: Link to area for editing the object.
•Status information items: Here is the information about the status of the
configurable function displayed for monitoring purposes. These items can
not be changed from this particular page.
There is also other configurable information items: These items consist of
web-browser-style user dialogue boxes, e.g. pull-down menus, text input
boxes and buttons. Any current configuration data is shown.

Frequently used terms
The following terms and parameters are frequently used throughout the Element
Manager:
Admin: The administrative status of the object (e.g. route, interface, server,
card or function). The operator can either set the administrative status to Up if
the object is to be activated, or to Down if it is to be deactivated.
Oper: The operational status of the object (e.g. route, interface, server, card
or function). Up indicates that the object is active, while Down indicates that it
is inactive. If the operational status shows Down while the administrative status
is Up this is an indication of that an error has occurred.
Toggle Admin: Before any parameters can be changed, the administrative
status of the interface must be set to down. To simplify this procedure, Toggle
admin tells the node to set the administrative status of the interface to down,
reconfigure all parameters and then set the administrative status to the
configured value.
Local node:Is also mentioned as source and originating node.
Remote node: Is also mentioned as destination, terminating and sink node.
Logging in using the Telnet connection
Terminal connection, Nimbra 340
1. Establish communication with a unit over a TCP/IP network. If the unit
has just been installed, you must first use the local serial connection
according to the Nimbra 340 Installation and Maintenance Manual.
2. Start a Telnet client and enter connect (IP address of
the unit) and press [Enter].
When connection is established the following information appears on the
terminal:
nimbra 340 login:_
3. Enter the user name and, when prompted for, the password.
Password:_
Nimbra pre-release 0.1
nimbra340:~ #
The unit is now ready to receive commands. For a further description of
commands, please see Reference chapter, section Nimbra 340 CLI commands.
Logging in using a web browser
1. Establish the connection, either locally or remotely, and start the browser.
2. Enter the name or the IP-address of the unit in the address field. A Web
interface start page, similar to Figure 5, will appear in the browser
window.
