Introduction to SPMA for the TSX-1620
How to use the TSX-1620 User’s Guide; manual conventions; contacting Cabletron Technical Support;
TSX-1620 firmware versions supported by SPMA
The TSX-1620 is a high-speed stand-alone Token Ring switch with the ability to
transparently switch packets among its various attached ring networks at full line
rate (4 or 16 Mbps) and with minimal latency. The TSX-1620 provides source
routing functions while using store and forward switching technology. The TSX-
1620 also provides virtual networking capability, allowing you to configure
logical rings that include multiple physical rings attached to the front panel ports
(e.g., physical rings inserted in ports 1, 2, 5, and 8 could all be assigned to a single
virtual ring network, and would communicate as if they actually were on the
same physical ring). Using this capability, 4 and 16 Mbps devices can be placed on
separate physical rings (each port automatically determines the speed of the ring
to which it is connected), allowing the 16 Mbps devices to operate at full speed,
and the switch can treat both rings as a single logical ring network. Broadcast
discovery packets can be confined to a virtual subset of the attached rings, thereby
reducing overall traffic on the switch.
The TSX-1620 is an 8 port switch which is expandable to 16 ports, with STP/UTP
and 4 or 16 Mbps on each port via front panel RJ-45 connectors. The device is
IEEE 802.5 compliant with support for IEEE 802.1d spanning tree, and supports
SNMP, including MIB II.
Using the TSX-1620 User’s Guide
Your SPECTRUM Portable Management Application (SPMA) for the TSX-1620
consists of a number of different applications, each of which provides a portion of
the overall management functionality. Each of these applications can be accessed
from the icon menu (if you are using a management platform) and from the
Stand-alone Launcher or the command line (if you are running in stand-alone
1-1
Introduction to SPMA for the TSX-1620
mode); in addition, several applications can also be accessed from within the Hub
View, a graphical display of the TSX-1620 and its ports.
The TSX-1620 User’s Guide describes how to use many of the applications
included with the module; note that the instructions provided in this guide apply
to the TSX-1620 module regardless of the operating system or management
platform you are using. Instructions for launching each individual function from
the command line (stand-alone mode) are also included in each chapter.
Following is a description of the applications documented in this guide; while we
provide as much background information as we can, we do assume that you’re
familiar with Ethernet networks and general bridging and network management
concepts:
• Chapter 1, Introduction to SPMA for the TSX-1620 , describes the TSX-1620
User’s Guide and the conventions used in this and other SPMA manuals,
explains where to find information about the TSX-1620, and tells you how to
contact Cabletron Systems Technical Support.
• Chapter 2, Using the TSX-1620 Hub View , describes the visual display of the
Hub and explains how to use the mouse within the Hub View; the operation
of some basic functions (changing the Hub View display, opening menus and
windows, enabling and disabling ports, checking device status, and so on)
available only from within the Hub View is also described. You can access the
Hub View application from the icon menu or the command line.
• Chapter 3, Using the TSX-1620 Bridge View , provides detailed instructions
for configuring and managing the TSX-1620’s powerful bridging capabilities,
including monitoring bridge operation, using the filtering database, and
setting forwarding thresholds and notification options. You can access the
Bridge View from the Hub View, the icon menu or the command line.
What’s NOT in the TSX-1620 User’s Guide. . .
The following standard SPMA tools are available through the TSX-1620 module
and are explained in the SPECTRUM Portable Management Application Tools
Guide :
• MIB I, II
• MIBTree
The MIB I, II application is available from the Hub View, the platform console
window Tools menu, the Stand-alone Launcher window, or the command line.
The MIBTree application is available from the platform console window Tools
menu, the Stand-alone Launcher window, or the command line.
Instructions on discovering Cabletron devices, creating icons, and accessing the
icon menus within your management platform are included in your Installing
and Using SPECTRUM for... guide. If you are using SPMA for the TSX-1620 in
stand-alone mode — that is, without benefit of a specific network management
1-2 Using the TSX-1620 User’s Guide
system — instructions for starting each application from the command line are
included in each chapter, both in this guide and in the SPMA Tools Guide .
Conventions
SPECTRUM Portable Management Applications — including the TSX-1620
module — can work with a number of different network management systems
running on several different operating systems and graphical user interfaces. This
versatility presents two documentation problems: first, there is no standard
terminology; and second, the appearance of the windows will differ based on the
graphical interface in use. For the sake of consistency, the following conventions
will be followed throughout this and other SPMA guides.
Screen Displays
Introduction to SPMA for the TSX-1620
SPMA runs under a variety of different operating systems and graphical user
interfaces. To maintain a consistent presentation, screen displays in this and other
SPMA guides show an OSF/Motif (X Windows) environment. If you’re used to a
different GUI, don’t worry; the differences are minor. Buttons, boxes, borders, and
menus displayed on your screen may look a bit different from what you see in the
guide, but they’re organized and labelled the same, located in the same places,
and perform the same functions in all screen environments.
Some windows within SPMA applications can be re-sized; those windows will
display the standard window resizing handles employed by your windowing
system. Re-sizing a window doesn’t re-size the information in the window; it just
changes the amount of information that can be displayed (see Figure 1-1). When
you shrink a window, scroll bars will appear as necessary so that you can scroll to
view all the information that is available.
Conventions 1-3

Use the scroll bars
provided to choose

message history
Figure 1-1. Window Conventions
Some windows will also contain a button; selecting this button
launches a History window (Figure 1-2) which lists all footer messages that have
been displayed since the window was first invoked. This window can help you
keep track of management actions you have taken since launching a management
application.
1-4 Conventions
Introduction to SPMA for the TSX-1620
Using the Mouse
The UNIX mouse has three buttons. Procedures within the SPMA document set
refer to these buttons as follows:
Figure 1-2. The History Window
Button 1
Button 2
Button 3
Figure 1-3. Mouse Buttons
If you’re using a two-button mouse, don’t worry. SPMA doesn’t make use of
mouse button 2. Just click the left button for button 1 and the right mouse button
when instructed to use mouse button 3.
Conventions 1-5
Introduction to SPMA for the TSX-1620
Whenever possible, we will instruct you on which mouse button to employ;
however, menu buttons within SPMA applications will operate according to the
convention employed by the active windowing system. By convention, menu
buttons under the Motif windowing environment are activated by clicking the left
mouse button (referred to as mouse button 1 in SPMA documentation), and there
is no response to clicking the right button (mouse button 3). Under
OpenWindows, menu buttons can be activated by clicking the right button, and
convention dictates that the left button activates a default menu option; within
SPMA, that default option will also display the entire menu. Because of this
difference, references to activating a menu button will not include instructions
about which mouse button to use. All other panels from which menus can be
accessed, and all buttons which do not provide access to menus, will operate
according to SPMA convention, as documented.
Getting Help
If you need additional support related to SPMA, or if you have any questions,
comments, or suggestions related to this manual, contact Cabletron Systems
Technical Support. Before calling, please have the following information ready:
• The product name and part number
• The version number of the program that you need help with. SPMA is
modular, which means each application will have a specific revision number.

Chapter 2
The heart of the SPECTRUM Portable Management Application (SPMA) for the
TSX-1620 is the Hub View, a graphical interface that gives you access to many of
the functions that provide control over the TSX-1620.
Using the Hub View
There are two ways to open the Hub View: if you are working within a network
management system, you can select the Hub View option from the icon menu;
specific directions for creating a TSX-1620 icon and accessing the icon menu can
be found in the appropriate Installing and Using SPECTRUM for... guide. If you
are running the TSX-1620 module in a stand-alone mode, type the following at the
command line:
spmarun tsxmod <IP address> <community name>
The community name you use to start the module must have at least Read access;
for full management functionality, you should use a community name that
provides Read/Write or Superuser access. For more information on community
names, consult the appropriate Installing and Using SPECTRUM for... guide,
and/or the Community Names chapter in the SPMA Tools Guide .
2-1
Using the TSX-1620 Hub View
The spmarun script invoked first in the above command temporarily sets the environment
NOTES
variables SPMA needs to operate; be sure to use this command any time you launch an
application from the command line. This script is automatically invoked when you launch
an application from the icon menu or from within the Hub View.
If you wish to configure your TSX-1620 in any way, be sure to use a community name
with at least Read/Write access. If you only wish to view current settings, a community
name with Read access will be sufficient.
If there is a hostname mapped to your TSX-1620’s IP address, you can use <hostname> in
place of <IP address> to launch this application. Please note, however, that the hostname
is not the same as the device name which can be assigned via Local Management and/or
SPMA; you cannot use the device name in place of the IP address.
Navigating Through the Hub View
Within the Hub View, you can click mouse buttons in different areas of the
window to access various menus and initiate certain management tasks. The
following diagrams describe the information displayed in the Hub View and
show you how to use the mouse to display the TSX-1620’s menus.

Hub View Front Panel
In addition to the graphical display of the TSX-1620’s ports, the Hub View gives
you device level summary information. The following Front Panel information
appears to the right of the port display in the Hub View:
Contact Status is a color code that shows the status of the connection between
SPMA and the device:
• Green indicates a valid connection.
• Blue means that SPMA is trying to reach the device but doesn’t yet know if the
connection will be successful.
• Red means that SPMA is unable to contact or has lost contact with the device.

The device’s Internet Protocol address; this field will display the IP address you
have used to create the TSX-1620 icon (if you are running the Hub View from a
management platform) or the IP address you used to launch the Hub View
program (if you are running in stand-alone mode). You cannot change the TSX1620’s IP address from SPMA.
Clicking the Device button displays the Device menu, Figure 2-2, which lets you
open the Polling Intervals window.
Figure 2-2. TSX-1620 Hub View Device Menu
See Setting the Polling Intervals on page 2-15 for details about the Polling
Intervals window.
Note that the Device menu does not provide access to every application which is
available to the TSX-1620; some information is only available from the Module,
Interface, Bridge, and/or Bridge Port menus, and several applications can only be
accessed either from the icon menu (if you are running under a network
management platform) or from the command line (if you are running in standalone mode). See Chapter 1, Introduction to SPMA for the TSX-1620, for a
complete list of applications available to the TSX-1620 and how to access each
one.
2-4 Using the Hub View
Clicking mouse button 1 on the Quit button closes all Hub View application
windows; any open applications which can also be accessed from the command
line or from the icon menu will remain open.
Using the Mouse in the TSX-1620 Hub View

Monitoring Device Performance
The information displayed in the Hub View can give you a quick summary of
device activity, status, and configuration. SPMA can also provide further details
about hub performance via its four-level menu structure. The Device, Module,
Interface/Bridge and Bridge Port menus give you control over the device at four
levels for both the Interface and Bridge application displays and give you access
to the tools, menus, and windows that let you monitor specific aspects of device
performance, change display options, and set TSX-1620 operating and notification
parameters. See Figure 2-5 and Figure 2-6 to view the different menus and their
contents.
Port Display Form
You can change the type of information displayed for each port by using the Port

1. Click in the appropriate area to display the Interface or Bridge menu (refer to
Figure 2-3 on page 2-5).
2. Dr ag down to P ort Display Form, then right as necessary to select one of the
port display options. The current selection will be displa y ed in the Port Display
Form text box, just above the ports.
Interface Port Display Form Options
Oper Status
The Oper Status port display form displays the current status of the port — ON,
OFF, NLK (no link), Test, or --- (unknown). Oper Status is determined by a
combination of MIB-II interface operational status (ifOperStatus), administrative
status (ifAdminStatus), and the interface’s physical link status (if applicable).
• The ON status indicates that the interface’s operational status is determined as
“UP”, that it has been administratively enabled, and that a physical link has
been detected at the port. A status of ON indicates that the port can send and
receive NMS packets, but does not indicate whether the port’s bridging
functions are enabled.
To determine whether a port’s bridging functions are enabled, change the application

• A status of OFF indicates that the port has been physically disabled, or is
broken.
• NLK (no link) indicates that the interface’s operational status is determined as
“UP”, and it has been administratively enabled, but no physical link state to
the port has been detected.
• A status of Test indicates that the interface is in some operational or
administrative test status, and is unable to pass packets.
• The --- (unknown) status indicates that the state of the port’s operational, link,
and administrative states were not returned from the device.
Type
Displays the MIB-II ifType. As defined by the MIB “the type of interface,
distinguished according to the physical/link protocol(s) immediately below the
network layer in the protocol stack.”
Speed
Displays the operating speed of the interface; as defined by the MIB-II ifSpeed,
“An estimate of the interface’s current bandwidth in bits per second. For
interfaces which do not vary in bandwidth or for those where no accurate
estimation can be made, this object should contain the nominal bandwidth.”
Interface Number
Displays each port’s interface number, including the network management port.
Statistics
From the Interface or Bridge menu, you can display any one of the statistics
detailed below:
• Load will display the percentage of total, inbound, or outbound network load
processed by each port during the last polling interval.
- Total will display the percentage of total, inbound, and outbound network
load processed by each port during the last polling interval. This
percentage reflects the network load generated per polling interval by
devices connected to the port (determined by adding the change in the
port’s MIB-II ifInOctets and ifOutOctets values during the last polling
interval and multiplying by 800) compared to the port’s ifSpeed value.
- In shows the percentage of packets received during the last polling
interval from devices connected to the port. This percentage reflects the
packets received (determined by the change in the port’s MIB-II ifInOctets
value during the last polling interval, multiplied by 800) compared to the
port’s ifSpeed value.

Port Color Codes for the Interface Application Display
For each port display form, the color-coding of each interface reflects a
combination of MIB-II interface operational status (ifOperStatus), administrative
status (ifAdminStatus), and the interface’s physical link status (if it applies).
Green On — The interface’s operational status is returned as “UP” —
and it has been administratively enabled; if the interface
supports link state, a physical link has been detected at the port.

Admin
Display’s the port’s current bridging status — FWD (forwarding), DIS (disabled),
LIS (listening), LRN (learning), BLK (blocking), BRK (broken), or UNK
(unknown). These bridge port status conditions are defined as follows:
• FWD (forwarding) when the interface is on-line and forwarding packets from
one network segment to another.
• DIS (disabled) when bridging at the interface has been disabled by
management, and no traffic can be received or forwarded on this interface.
• LIS (listening) when the interface is not adding information to the filtering
database. It is monitoring Bridge Protocol Data Unit (BPDU) traffic while
preparing to move to the forwarding state.
• LRN (learning) when the Forwarding database is being created, or the
Spanning Tree Algorithm is being executed because of a network topology
change.
• BLK (blocking) when the interface is on-line, but filtering traffic from going
across the TSX-1620 from one network segment to another.
• BRK (broken) when the physical interface has malfunctioned.
• UNK (unknown) if the interface’s status cannot be determined.

Port Color Codes for the Bridge Application Display
No matter which Bridge Port Status display form is selected, each bridge interface
is color-coded to reflect the Bridge Port state, as follows:
• Blue — The bridge port is administratively Disabled.
• Magenta — The bridge port is in the Listening or Learning state.
• Green — The bridge port is on line and Forwarding.
• Orange — The bridge port is currently Blocking.
• Red — The bridge port is malfunctioning.
• Gray — No information is being returned from the interface; its ifOperStatus
is not being returned.
