Introduction

About the MultiSwitch 700; how to use this guide; related guides; software conventions; getting help

Welcome to the MultiSwitch 700 Modules User’s Guide. We have designed this
guide to serve as a reference for using NetSight Element Manager for the
MultiSwitch 700 product, which encompasses the DLM6C-AA cha ssis and the
MultiSwitch 700 modules.

The MultiSwitch 700 product encompasses the DLM6C-AA chassis and the
MultiSwitch 700 modules. The DLM6C-AA hub is a stand-alone chassis that
offers five slots for interface modules; it also has two slots for dual redundant
power supplies (installed vertically to the right of the module slots), and a
removable fan tray (installed horizontally ac ross the botto m the chassis).

At the heart of the MultiSwitch 700 is its Frame Transfer Matrix (FTM) backplane

and distributed processing power. The FTM’s passive design provides a separate
independent backplane connection from each module in the chassis to every other
module installed in the chassis; each module contains its own active switching
components (so switching horsepower increases with module density), and each
module can be managed independently (via its Module Manager management
component) or — for devices which support distributed management — as part
of the chassis unit (via a sing le chassis IP/MAC address pair and the Chassis
Manager management component).

There are several varieties of MultiSwitch 700 modules currently available:

•The DLE22-MA and DLE23-MA modules each provide 24 fixed 10Base-T

switch ports (via RJ45 connectors on the DLE22-MA; RJ21 Telco connectors on
the DLE23-MA) and two slots for optional Fast Ethernet port interface
modules. Several Fast Ethernet port interface modules are available:

- the DELFX-UI, which provides one multi-mode fiber port via an SC

connector;

- the DELTX-UI, with one Category 5 UTP RJ45 connector;

- and the DELF3-UI, with one single-mode fiber port via an SC connector.

1-1

Introduction

•The DLE32-MA and DLE33-MA modules each provide 24 fixed 10Base-T

switch ports (via RJ45 for the DLE32-MA and RJ21 for the DLE33-MA) and one
slot for an optional modular interface that can link the chassis to an FDDI,
ATM, WAN, or Gigabit Ethernet backbone. Each modular interface provides
frame translation between ATM, FDDI, WAN, Gigabit Ethernet, and Ethernet
through an on-board Intel i960 processor:

- The DELHF-UA is an FDDI/Ethernet Translator, which can act as a Sin gle

Attached Station (SAS) or Dual Attached Station (DAS) on an external
FDDI ring. FDDI Port Interface Modules provide a wide range of media
connectivity to the ring. The DELHF-UA also has full-duplex capability,
allowing for a 200 Mbps connection to another DELHF-UA.

- The DELHA-UA is an Asynchronous Transfer Mode (ATM) modular

interface, which provides an ATM uplink via two media-configurable
AT M Port Interface Modules. The dual port interface module design
allows for a redundant connection to the uplink, so that if the primary
interface fails, the secondary interface will automatica lly take over. The
DELHA-UA acts as an ATM Forum LAN Emulation Client (LEC) so that
it can transfer data between devices on an 802.x LAN supported by the
MultiSwitch 700 and ATM-connected end stations across a high speed
AT M Link. The DELHA-UA adheres to the ATM Forum-approved LAN
Emulation (LANE) standard, which defines how end users that rely on
existing data communications technology and protocols can oper ate o ver
an ATM network without penalty.

NOTE

- The DELHW-UA is a Wide Area Networking (WAN) modular interface,

which can provide uplinks to WAN backbones and allow you to perform
seamless LAN to WAN switching. The DELHW-UA supports IP and IPX
bridging or routing services, including IP RIP . Multiple W AN connectivity
options are supported, including Sync, T1, E1, D&I, ISDN S/T, DDS, and
HDSL interfaces, through the use of two configurable WAN port interface
modules. Connectivity is available for Po int to Point Protocol (PPP), as
well as Frame Relay and Leased Lines. Each WAN port interface module
can act independently, allowing simultaneous communication, or
configured to provide redundant channels if desired.

Unlike other modular interfaces designed for the MultiSwitch 700 boards, the
DELHW-UA module functions as an independent intelligent device with its own IP
address. As such, it must be managed separately from the MultiSwitch 700 chassis and
the board on which it is installed.

The DELHW-UA’s WAN functionality is accessed from the DELHW-UA’s Device View.
See The DELHW-UA Device View, on page 2-75 of Chapter 2, The MultiSwitch 700

Device View, for instructions on launching the DELHW-UA Device View. Other

DELHW-UA Device View functions, such as finding a source address and changing the
device time and date, are also described there.

Chapter 7, WAN Configuration, provides information on configuring and managing the
WAN capabilities of the various port modules available for the DELHW-UA.

Introduction

- The DELHG-UA and DELHL-UA are Gigabit Ethernet modular

interfaces, each of which provide a single Gigabit E thernet connection that

fully conforms to the IEEE P802.3z (D3.1) Draft Standard. The

DELHG-UA provides a single 1000Base-SX (short-wave) multimode fiber

optic SC interface, allowing for link distances of up to 500 meters. The

DELHL-UA provides a single 1000Base-LX (long-wave) single

mode/multimode fiber optic SC interface, allowing for link distances of

up to 3 kilometers.

•The DLE28-MA module provides 24 fixed Ethernet multi-mode fiber por ts via

ST connectors, plus a single slot for a modular interface.

•The DLE49-MA module provides 48 switched Ethernet ports via four RJ21

Telco connectors and a single modular interface slot.

•The DLE02-MA and DLE52-MA modules are 10/100 Fast Ethernet modules.

The DLE02-MA provides 24 ports via RJ45 connections. The DLE52-MA
provides 16 ports via RJ45 connections as well as a next-generation modular
interface slot, which can accept any of the previously detailed modular
interfaces, or the new DELVM-UA Gigabit Ethernet modular interface:

- The DELVM-UA is a Gigabit Ethernet module which provides two slots

for Gigabit Ethernet port interface modules of various media to offer

integrated Gigabit Ethernet uplink capability . The DELVM-UA can accept

the DELG1-UA, which offers one SC connector for MMF 1000Base SX

Gigabit Ethernet connectivity, the DELG9-UA, which offers one SC

connector for MMF or SMF 1000Base LX connectivity, or the DELG4-UA,

which offers one ANSI Fibrechannel style-2 connector for 150 Ohm STP

1000Base CX connectivity.

•The DLEHF-MA carrier module provides two Fast Ethernet port interface

module slots and two modular interface slots.

Each of these modules provide key mission-criti c al features such as redundant
links for load sharing, alarm th resholdi ng, broadcast storm control, port
redirecting for traffic analysis, traffic priority configuration, and full error
breakdown. Per-port RMON support is also provided. By default, these modules
perform traditional switching (or bridging); each ca n also be configured to
perform prestandard IEEE 802.1Q VLAN switching (a.k.a “port-based VLAN”
switching).

The DLM6C-AA MultiSwitch 700 chassis itself offers the following features:

• Slots for up to 5 double-wide 2.4" interface modules, with chassis-wide

support of up to 130 users. Each interface module is individually driven and
managed by on-board processors, including an onboard ASIC processor for
switching, and Intel i960 Host microprocessors for dedicated module
management.

• A Frame Transfer Matrix (FTM) backplane design, that provides a separate

independent backplane connection from each module in the chassis to every
other module installed in the chassis. This allo ws a backplane bandwidth
capacity of up to 3.2 Gbps.

1-3

Introduction

• Support for redundant, load-sharing power supplies to provide fault
tolerance.

• Diagnostic LEDs for quick visual diagnosis of interface and device
performance; a single removable fan tray; a 19" footprint for ease of installation
in rack mounts; and front panel accessibility to all chassis components for easy
maintenance.

• A distributed chassis management design, in which each module in the chassis
can be managed via a single chassis IP/MAC address pair that is associated
with the chassis as a whole. Each installed module will respond to
management queries to the “Chassis Manager” component that use the chassis
IP/MAC address pair and a chassis-level community string (e.g., “public”).

In addition to the “Chassis Manager” component for the hub as a w hole, each
installed module supports its own “Mo d ule Manager” management
component that responds to the same chas sis IP/MAC pair and a uniquely
indexed module-level community string (e.g., “public.1” for module 1;
“public.2” for module 2, etc.).

Using the MultiSwitch 700 Modules User’s Guide

Each chapter in this guide describes one major functionality or a collection of
several smaller functionalities of the MultiSwitch 700 modules and the chassis in
which they are installed. This guide contains information about software
functions which are accessed directly from the device icon.

Because the modules share much of their functionality, they will be collectively
referred to as the MultiSwitch 700 modules. Where there are dif ferences, h owever,
each device will be named separately, as necessary. The information displayed in
many of the windows will differ slightly depending upon which type of device is
being managed; however, only a single window will be shown unless significant
differences in functionality exist.

Chapter 1, Introduction, provides a list of related documentation, describes
certain software conventions, and shows yo u ho w to c o nt a c t t h e Gl ob a l Technical
Assistance Center. It also briefly describes the MultiSwitch 700 modules and
chassis.

Chapter 2, The MultiSwitch 700 Device View, describes the visual display of the
MultiSwitch 700 chassis as a whole and explains how to use the mouse within the
Device View. It details all chassis-level management fun ctions, including Port
Redirect, Advanced Priority Configuration, and pre-standard 802.1Q port-based
VLAN configuration at the chassis level. It documents chassis-specific
information, including MIB-II System Group information, chassis IP and MA C
addresses, chassis clock information and uptime, power supply configuration and
status, fan operational status, and backplane configuration.

The chapter also details how each module is displayed in the chassis, and
explains how to access management menus from the module display and change
port status information. It explains how to manage the individual module by

Introduction

monitoring the module’s system resources, finding a source address on the
module, establishing module-level port priorities, setting up broadcast
suppression on the device, and configuring the module’s front panel COM port
and any attached Uninterruptable Power Supply (UPS).

Also described in this chapter is the Device View f unctionality associated with the
DELHW-UA modular interface. Unlike other modular interfaces designed for the
MultiSwitch 700 boards, the DELHW-UA module functions as an independent
intelligent device with its own IP address. As such, it must be managed separately
from the MultiSwitch 700 chassis an d the boa rd on which it is installed.

Chapter 3, Statistics, describes the two statistics views available at the interface
level: MIB-II Interface statistics and RMON Ethernet statistics.

Chapter 4, Alarm Configuration, provides instructions for using both the Basic
and Advanced alarm applications to configure alarms and the events that notify
you that an alarm condition has occurred. The ability to automatically initiate a
SET or a series of SETs in response to an alarm — functionality provided by the
proprietary Actions MIB — is also described.

Chapter 5, FDDI Management, describes the Configuration, Connection Policy,
Station List, Performance, FDDI Statistics, and Fra me Translation selections
available when a DELHF-UA module is installed.

Chapter 6, ATM Configuration, discusses the ATM Connections window which
will appear if you have a DELHA-UA module installed in your device.

Chapter 7, WAN Configuration, describes the physical configuration of the
DELHW-UA modular interface, including port interface module options, and
explains the WAN Logical View window and its functions.

Software Conventions

NetSight Element Manager’s device user interface contains a number of elements
which are common to most windows and which operate the same regardless of
which window they appear in. A brief description of some of the most common
elements appears below; note that the information provided here is not repeated
in the descriptions of specific windows and/or functions.

Common Window Fields

Similar descriptive information is displayed in boxes at the top of most
device-specific windows in NetSight Element Manager, as illustrated in

Introduction

Device Name

Displays the user-defined name of the device. The device name can be changed
via the System Group window; see the Gener ic SNMP User’s Guide for details.

IP Address

Displays the device’s IP (Internet Protocol) Address. This will be one of two
addresses:

• The Network IP address assigned to the MultiSwitch 700 chassis (if a

network-level IP address has been assigned to the module).

• The individual module IP address (if IP addresses have been assigned on a

per-module basis).

Both of these IP address are assigned via Local Management to the Host interface
of each module in the MultiSwitch 700 chassis. The IP addresses cannot be
changed remotely via NetSight Element Manager. Note that altho ugh each
interface on the MultiSwitch 700 module has its own MAC, or physical, address,
only a single IP address is assigned to the module or cha ssis as a whole.

Location

Displays the user-defined location of the device or chassis. The location is entered
through the System Group window; see the Generic SNMP User’s Guide for

details.

MAC Address

Displays t he manufa cturer-set MAC address associated with the network IP
address of the MultiSwitch 700 chassis, or the module IP address of the currently
monitored Multi Switch 70 0 module. No te that MAC addr esses ar e factory -set and
cannot be altered through management.

Using the Mouse

This document assumes you are using a Windows-compatible mouse with two
buttons; if you are using a three button mouse, you should ignore the operation of
the middle button when following procedures in this document. Procedures
within the NetSight Element Manager document set refer to these buttons as
follows:

Software Conventions 1-7

Introduction

Left Mouse Button

Right Mouse Button

Figure 1-2. Mouse Buttons

For many mouse operations, this document assumes that the left (primary) mouse
button is to be used, and references to activating a menu or button will not
include instructions about which mouse button to use.

However, in instances in which right (secondary ) m ouse button functionality is
available, instructions will explic itly refer to right mouse button usage. Also, in
situations where you may be switching between mouse buttons in the same area
or window, instru ctions may also explicitly refer to both left and right mouse
buttons.

Instructions to perform a mouse operation include the following terms:

• Pointing means to position the mouse cursor over an area without pressing
either mouse button.

• Clicking means to position the mouse pointer over the indicated target, then
press and release the appropriate mouse button. This is most commonly used
to select or activate objects, such as menus or b uttons.

• Double-clicking means to position the mouse pointer over the indicated
target, then press and release the mouse button two times in rapid succession.
This is commonly used to activate an object’s default operation, such as
opening a window from an icon. Note that there is a distinction made between
“click twice” and “double-click,” since “click twice” implies a slower motion.

• Pressing means to position the mouse pointer over the indicated target, then
press and hold the mouse button until the de scribed action is completed. It is
often a pre-cursor to Drag operations.

• Dragging means to move the mouse pointer across the screen while holding
the mouse button down. It is often used for drag-and-drop operations to copy
information from one window of the screen into another, and to highlight
editable text.

1-8 Software Conventions

Using Buttons

Introduction

The Cancel button that appears at the bottom of most windows allows you to exit
a window and terminate any unsaved changes you have made. You may also
have to use this button to close a window after you have made any necessary
changes and set them by clicking on an OK, Set, or Apply button.

An OK, Set, or Apply button appears in windows that have configurable values;
it allows you to confirm and SET changes you have made to those values. In some
windows, you may have to use this button to confirm each individual set; in other
windows, you can set several values at once and confirm the sets with one click
on the button.

The Help button brings up a Help text box with informat ion specific to the
current window. For more information concerning Help buttons, see Getting

Help, on page 1-9.

The command buttons, for example Bridge, call up a menu listing the wind ows,
screens, or commands available for that topic.

Any menu topic followed by ... (three dots) — for example Statistics... — calls up
a window or screen associated with that topic.

Getting Help

This section describes three different methods of getting help for questions or
concerns you may have while using NetSight Element Manager.

General Device Information

In addition to the main interface display, the Device View window provides the
following device information:

IP

The Device View window title displays the device’s IP (Internet Protocol)
Address; this will be the MultiSwitch 700 module IP address used to define the
device icon. The IP address is assigned to the MultiSwitch 700 module via the
Device Configuration portion of Local Management; it cannot be changed via
NetSight Element Manager. Note that although each interface in the MultiSwitch
700 module has its own MAC, or physical, a ddress, only a single IP address is
assigned to the device.

Connection Status

This color-coded area i ndicates the current state of communication between
NetSight Element Manager and the MultiSwitch 700 module.

• Green indicates the MultiSwitch 700 module is responding to device polls
(valid connection).

• Magenta indicates that the MultiSwitch 700 module is in a temporary stand-by
mode while it responds to a physical change in the hub (such as when a
module is inserted). Note that module and port menus are inactive during this
stand-by state.

• Blue indicates an unknown contact status; polling has not yet been established
with the MultiSwitch 700 module.

• Red indicates the MultiSwitch 700 module is not responding to device polls
(device is off line, or device polling has failed across the network for some
other reason).

Chassis Type

The model of chassis — MultiSwitch 700—þin which the monitored
MultiSwitch 700 module is installed.

Location

A descriptive field you can use to identify where the chassis is physically located.
You can edit this field through the device’s System Group window; refer to the

Generic SNMP User’s Guide for details.

UpTime

The amount of time, in a days hh/mm/ss format, that the MultiSwitch 700
module has been running since the last start-up. Note that when distributed
chassis management is available, this field will indicate the time that the longest
active module has been running since start-up.

The MultiSwitch 700 Device View

DLM6C-AA Chassis-specific Information

The Device View provides the following information about the DLM6C-AA
chassis in which the MultiSwitch 700 module is installed. There are four
color-coded fields which provide status information for the operation of the
power supplies and fan tray installed in the DLM6C-AA chassis.

Power Redundancy

The DLM6C-AA supports two power supply modules. Each supports a separate
AC input connector, so that two separate power sources can be used for the
chassis. Additionally, with two power supplies installed, the total load presented
by the DLM6C-AA and its installed modules is split 5 0/50 between the supplies
(+/- 5%). The Power Redundancy field displays whether or not the chassis is
currently configured for load sharing and power redundancy. Possible values are:

• Available (Green) — Two HA-205-XX power supply modules are installed in
the DLM6C-AA chassis.

• Not Available (Yellow) — Only a single HA-205-XX power supply module is
installed in the DLM6C-AA chassis. Note that when only a single power
supply module is installed, it must always be in power slot 1 (PS1).

PS #1/#2 Status

Indicates the state of any power supplies insta lled in the DLM6C-AA Chassis.
Possible states returned are:

• Not Available (Yellow) — No response has been returned from the device
regarding the power supplies.

• Normal (Gr een) — A power supply is installed and operatin g in the associated
power slot.

• Fault (Red) — The power supply in the associated power slot is not
operational.

• Not Installed (Blue) — The indicated power slot is not occupied by a power
supply.

Fan Tray Status

The DLM6C-AA supports a single, removable fan tray that has four fans. The tray
is hot swappable, so it can be removed without powering do wn the chassis. This
field indicates the status of the DLM6C-AA’s Fan Tray:

• Not Available (Yellow) — No response has been returned regard ing the fan
tray.

• Normal (Green) — A fan tray is installed and operational.

• Fault (Red) — One or more fans in the tray have failed.

• Not Installed (Blue) — The fan tray slot is not occupied. The chassis is in
danger of overheating if it continues to run without the fan tray installed.

The Chassis Manager Window

The MultiSwitch 700 modules draws its f unctionality from a collection of
proprietary MIBs and IETF RFCs, and organizes the MIB data into a series of
components. A MIB component is a logical grouping of MIB data, and each group
controls a defined set of objects. For example, MultiSwitch 700 module bridging
information is organized into its own component; Local Management (LIM) and
RMON are also contained in separate components. There is no one-to-one
correspondence between MIBs and MIB components; a single MIB component
might contain objects from several different proprietary MIBs and RFCs.

The Chassis Manager window, Figure 2-6, is a read-only window that displays the

MIBs and the MIB components — and, therefore, the functionality — supported
by the currently monitored device.

statistics; note that the first four statistics are also graphically displayed in the pie
charts.

Unicast

Displays the number of packets transmitted to or received from this interface tha t

chart, color-coded green.

Non-Unicast

Displays the number of packets transmitted to or received from this interface tha t
had a destination address that is recognized by more than one device on the

network segment. The multicast field includes a count of broadcast packets —
those that are recognized by all devices on a segment. These statistics are
displayed in the pie chart, color-coded dark blue.

Discarded

Displays the number of packets which were discarded even though they
contained no errors that would prevent transmission. Good packets are typically
discarded to free up buffer space when the network becomes very busy; if this is
occurring routinely, it usually m eans that network traffic is overwhelming the
device. To solve this problem, you may need to re-configure your bridging
parameters, or perhaps re-configure your network to add additional bridges or
switches.

These statistics are displayed in the pie chart, color-coded magenta.

Error

Displays the number of packets received or transmitted that contained errors.
These statistics are displayed in the pie chart, color-coded red.

Unknown Protocol

created under an unknown or unsupported protocol.

Packets Received

Displays the number of packets received by the selected interface.

Transmit Queue Size

Displays the number of packets currently queued for transmission from this
interface. The amount of device memory devoted to buffer space, and the traffic
level on the target network, determine how large the output packet queue can
grow before the MultiSwitch 700 module will begin to discard packets.

Managing the Module

In addition to the performance and configuration information described in the
preceding sections, the Device View also provides you with the tools you need to
configure your MultiSwitch 700 module and keep it operating properly. Hub
management functions include setting operating parameters for Ethernet, FDDI,
Fast Ethernet, Gigabit Ethernet, and COM ports; managing an attached UPS;
redirecting traffic from one module interface to another; setting port priority
parameters; configuring transmission thresholds for broadcast packets; viewing
and configuring system resources; setting device date and time; and enabling and
disabling bridging at specific port interfaces.

Configuring Ports

The Configuration options available for FDDI, Ethernet, Fast Ethernet, Gigabit
Ethernet and COM ports allow you to configure operating parameters specific to
each port type: for FDDI and standard Ethernet ports, you can set the Duplex

2-30 Managing the Module

WARNING

The MultiSwitch 700 Device View

For standard Ethernet interfaces, Full Duplex should only be enabled on an interface that
has a connection to a single destination address at the other end of the connection (i.e., it is
not a segment with an attached repeater cascading the connection to multiple destination
addresses).

Full Duplex mode disables the collision detection circuitry at the interface, so that both
Transmit and Receive wires can be used simultaneously. With a single destination address
at the other end of the connection (for example, if the connection was to a full duplex
interface on another switching module, or if a single file server was connected to the full
duplex switch port), this essentially doubles the available bandwidth from 10 Mbit/ sec to
20 Mbit/sec. The inter face at the other end of the conne ction must also have Full Dup l ex
enabled at the attached interface.

Full Duplex mode must be disabled if the interface is communicating with multiple
destinations simultaneous ly (i.e., if a repeater is cascaded from the interface), sinc e
Ethernet relies on Collision Sense for proper operation.

Similarly, an FDDI Full Duplex connection must also only be run point-to-point between
two supporting FDDI interfaces (e.g., another DELHF-UA), since the dual bandwidth is
attained by running data on both primary and secondary paths simultaneously. Since
Full Duplex overrides standard FDDI protocol (and eliminates ring redundancy), it will

not operate in a “ring” configuration, but only as a point-to-point high speed data trunk
between hubs. You must use Local Management to configure your DELHF- UA for Full
Duplex operation prior to making physical connections. Refer to your Local Management
Guide for more information.

Use the options in this window to select the desired mode:

Standard Mode

In Standard Mode, an interface can only either transmit or receive at any given
time, and must wait for one activity to be completed before switching to the next
activity (receive or transmit). In this mode, standard wire speeds (10 Mbps for
Ethernet, 100 Mbps for FDDI) are avail able.

Full Duplex

In Full Duplex Mode, an interface can both receive and transmit packets at the
same time, effectively doubling the available wir e speed to 20 Mbps (for Ethernet)
or 200 Mbps (for FDDI).

Be sure to click on Apply to set your changes; note that the interface’s current

mode can be determined by the field selected in the window.

Configuring Fast Ethernet Ports on First Generation Modules

The Port Configuration window available for Fast Ethernet ports on first
generation modules (e.g., a DELF3-UI, DELFX-UI, or DELTX-UI port interface
module) allows you to both view and set those ports’ available modes. All
100Base-TX Fast Ethernet ports can be configured to operate in either standard

From this window you can manually set the operational mode of the port, or —
for 100Base-TX interfaces — set the port to Auto-Negotiation so that the
appropriate operational mode can be determined automatically. The mode you
set will determine the speed of the port and whether it uses Full Duplex or
Standard Mode bridging.

(for a port slot wi t h no mod u le in s talled).

Link State

Displays the current connection status of the selected port: Link or No Link.

Current Operational Mode

Indicates which of the available operational modes is curr ently in ef fect: 10Base-T,

must use a mode which it is not currently advertising .

If Auto-Negotiation is the selected mode, the Current Operational Mode field
will indicate which mode was selected by the link partner. See Setting the

Desired Operational Mode, on page 2-35, for more information.

Advertised Abilities

For 100Base-TX ports which have been configured to ope rate in Auto-Negotiation
mode, this field allows you to select which of the operational modes available to
the port can be selected by the negotiating link partners.

NOTE

During Auto-Negotiation, each of the link partners will advertise all selected
modes in descending bandwidth order: 100Base-TX Full Duplex, 100Base-TX,
10Base-T Full Duplex, and 10Base-T. Of the selected abilities, the highest mode
mutually available will automatically be used. If there is no mode mutually
advertised, no link will be achieved.

If you have selected a specific operational mode for your 100Base-TX port, the
Advertised Abilities do not apply; the sel ect ed Advertised Abilities also do not

restrict the local node’s ability to set up a link with a partner who is not currently
Auto-Negotiating.

Auto-Negotiation is not currently supported for 100Base-FX ports.

Remote Capabilities

When the local node is set to Auto-Negotiation, this field will display the
advertised abilities of the remote link — even if the remote link is not currently set
to auto-negotiate. Possible values for this field are:

• 100Base-TX Full Duplex

• 100Base-TX

• 10Base-T Full Duplex

• 10Base-T

2-34 Managing the Module

NOTE

The MultiSwitch 700 Device View

• Link Partner does not support Auto-Negotiation — Auto-Negotiation is either

not supported by or is not currently selected on the remote port.

• Unknown — the link partner’s capabilities could not be determined.
When the local node is not set to Auto-Negotiation, this field will be grayed out,

even if the link partner is set to Auto-Negotiation and is advertising abilities.

If both link partners are set to Auto-Negotiation, but there is no mutually-advertised

operational mode, no link will be achieved, and both nodes may display the message “Link
Partner does not support Auto-Negotiation.” To resolve this situation, be sure both link
partners advertise all their abilities, or be sure they advertise at least one
mutually-available mode.

Setting the Desired Operational Mode

For any 100Base-TX port, you can specifically choose any one of the four available
operational modes, or you can select Auto-Negotiation mode, which allows the
port to negotiate with its link partner to find the highest mutually available
bandwidth. If you select Auto-Negotiation mode, you must also choose which of
the port’s bandwidth capabilities you wish to advertise to the link partner.

TIP

If you select Auto-Negotiation at both ends of a link, be sure at least one
mutually-advertised operational mode is available.

For a 100Base-FX port, the selection process is somewhat simpler;
Auto-Negotiation for these ports is not supported at this time, so you need only
choose between 100Base-FX standard mode and 100Base-FX Full Duplex.
However, you must still be sure that both link partners are set to the same
operational mode, or the link will be unstable.

To set your desired operational mode:

1. Click on the Desired Operational Mode combo box to display the menu of

available options; drag down to select the operational mode you wish to set.

For 100Base-TX ports, the available options are:

Auto Negotiation — the operational mode will be dynamically set based on
the modes selected in the Advertised Abilities field (where both link partners
are auto-negotiating) and the speeds and modes supported by the attached
device

10Base-T — 10 Mbps connection, Standard Mode
10Base-T Full Duplex — 10 Mbps connection, Duplex Mode
100Base-TX — 100 Mbps connection, Standard Mode

100Base-FX Full Duplex — 100 Mbps connection, Duplex Mode

2. If you have selected Auto-Negotiation (for 100Base-TX ports only), use the
Advertised Abilities field to select the operational capabilities you wish to
advertise to the port’s link partner. If both link partners will be

Configuring Ethernet Ports on Second Generation Modules

The Ethernet Configuration window available for Fast Ethernet and Gigabit
Ethernet ports on second generation modules (e.g., DLE49- MA and DLE52-MA)

allows you to both view and set those ports’ available speed, modes, and flow
control. All second generation modules support the ctEthernetParameters MIB.
All Ethernet ports that return at least one instance for a query of the
ctEtherSupportedDuplex OID will use the Ethernet Configuration window as
shown in Figure 2-17.

All 100Base-TX Fast Ethernet ports can be configured to operate in either standard
Ethernet (10 Mbps) or Fast Ethernet (100 Mb ps) mode, and each mode can be
configured to operate in Full Duplex effectively doubling the available wir e speed
(from 10 to 20 Mbps in standard Ethernet mode, or from 100 to 200 Mbps in Fast
Ethernet mode). 100Base-FX (fiber) ports can be configured to operate in their
standard 100 Mbps mode, or in Full Duplex mode. 1000Base-SX/LX/CX Gigabit
Ethernet ports are always configured to operate in 1000 Mbps, Full Duplex mode.

This window displays the mode currently in effect on the selected interface, and
provides some information (where it is available) about the interface’s link
partner.

2-36 Managing the Module

The MultiSwitch 700 Device View

To access the Ethernet Configuration Window:

1. Select the port you wish to configure; the Port Menu will display.

2. Click Configuration. The Ethernet Configuration window, Figure2-16, opens.

Figure 2-17. The Ethernet Configuration Window

If you select the Configuration option available for a standard Ethernet or FDDI interface,

TIP

or for a Fast Ethernet port on a first generation module, an entirely different window
displays; see Configuring Standard Ethernet and FDDI Ports, page 2-30, or

Configuring Fast Ethernet Ports on First Generation Modules, page 2-31, for

information on configuring these ports.

From this window you can manually set the operational mode of the port, or —
for 100Base-TX and 1000Base-SX/LX/CX interfaces — set the port to Auto
Negotiate so that the appropriate operational mode can be determined
automatically. The mode you set will determine the port’s speed, duplex mode,
and flow control.

Managing the Module 2-37

The window displays the following information about the selected Ethernet port:

Port Type

Displays the port’s type: 100Base-TX RJ-45or RJ71 (fo r built-in Fast Ethernet ports
and the FE-100TX Fast Ethernet port module), 100Base-FX MMF SC Connector
(for the FE-100FX Fast Ethernet port module), 1000Base-SX/LX/CX (for the
VHSIM-G6 Gigabit Ethernet port module), or Unknown (for a port slot with no
module installed).

Link State

Displays the current connection status of the selected port: Link or No Link.

Remote Auto Signal

Indicates whether the operating mode at the remote end of the link is set to Auto
Negotiate.

Auto Negotiate Config

Indicates whether Auto Negotiate signalling is in progress or has completed.
Possible values for this field are: configuring, complete, disabled, parallel detect
failed, or other.

!

CAUTION

Auto Negotiate Mode

Use this field to enable or disable Auto Negotiate for the port. If Auto Negotiate is
disabled, the port will use the speed, duplex mode, and flow control settings
specified in the Operational Mode fields. Note that 100-BaseFX ports do not
support Auto Negotiation; they must use the control settings specified in the
Operational Mode fields.

Operational Mode Fields

If the port is not set to Auto Negotiate then the settings in the Operational Mode
fields are used.

If you choose to select a specific mode of operation (rather than auto negotiation), you
should be sure that the link par tner supports the same mode. Otherwise, no link wi ll be
achieved.

For example, if you select Full Duplex mode and the li nk partner supports the sam e wire
speed but not Full Duplex, a link will be achieved, but it will be unstable and will behave
erratically.

If you select Auto-Negotiation, the local node will try to match the mode of the link
partner, even if the link partner is not set to auto-negotiate, and even if the local node
must use a mode which it is not currently advertising .

2-38 Managing the Module

The MultiSwitch 700 Device View

The Current Operational Mode settings indicate which of the available
operational modes is currently in effect. If Auto Negotiate is the selected mode,
the Current Operational Mode fields will indicate which mode was selected by
the link partner.

The Desired Operational Mode settings display the operational mode that is
currently selected for this port, and allows you to change the selection.

The following operational modes can be specified:

Speed

This field specifies a port speed of 10MB, 100MB, or 1000MB.

Duplex

This field specifies Half Duplex or Full Duplex mode for the port.

Flow Control

Flow control allows Ethernet devices to notify attached devices that congestion is
occurring and that the sending device should stop transmitting until the
congestion can be cleared. There are two commonly used methods of flow control:
Frame-based (operates on Full Duplex links) and Backpressure (operates on Half
Duplex links).

Ports set to Full Duplex mode have frame-based flow control, using pause
control frames. Frame-based flow control options are:

Symmetric The port is able to both receive and transmit pause control

frames.

Asymmetric RX This option appears only for Gigabit Ethernet ports. The port

will receive pause control frames, but will not transmit its own.

Asymmetric TX This option appears only for Gigabit Ethernet ports. The port is

capable of sending pause control frames, but will not
acknowledge received pause co ntrol frames.

Disabled Disables flow control on the port.
Auto Negotiat e Ports configured to operate in auto negotiation mode will only

use pause control frames if the negotiation process determines
that the link partner supports them. Both ends of the link must
support auto negotiation and a common mode of operation.

Ports set to Half Duplex mode use Backpressure flow control. Backpressure flow
control simply asserts the carrier sense signal out the port causing the device
transmitting to detect a collision, stop trans mitting data, and send the jam signal.
Backpressure flow control options are enabled or disabled.

Managing the Module 2-39

The MultiSwitch 700 Device View

Setting the Desired Operational Mode

For any 100Base-TX port, you can configure operational modes, or yo u can select
Auto Negotiate mode, which allows the port to negotiate with its link partner to
find the highest mutually available bandwidth a nd flow control. If you select

Auto Negotiate mode, you must also choose which of the port’s bandwidth and
flow control capabilities you wish to advertise to the link partner (refer to Auto

Negotiation Technologies , page 2-40).

100Base-FX ports do not support auto negotiation for bandwidth or flow control
capability, so you must choose between 100Base-FX Half Duplex and 100Base-FX
Full Duplex mode, and set the flow control option. However, you must still be
sure that both link partners are set to the same operational mode, or the link will
be unstable.

For 1000Base-SX/LX/CX ports the speed and duplex modes are always
configured at 1000MB Full Duplex. However, you can select Auto Negotiate
mode, which allows the port to negotiate with its link partner to find the highest
mutually available bandwidt h and flow control. If you select Auto Negotiate
mode, you must also choose which of the port’s bandwidth and flow control
capabilities you wish to advertise to the link partner (refer to Auto Negotiation

Technologies, page 2-40).

NOTE

To set your desired operational mode:

1. Click on the Speed, Duplex, or Flow Control list box to display the menu of
available options; click to select the operational mode you wish to set.

If the port you are configuring does not support Flow Control, the Current Mode field will

display “not supported” and the Desired Mode list box will be disabled.

2. Click on the Apply button to save your changes.

Auto Negotiation Technologies

For ports which have been configured to operate in Auto Negotiate mode, this list
box allows you to select which of the operational modes available to the port will
be advertised to the negotiating link partner.

During Auto Negotiation, each of the link partners will advertise all selected
modes. Of the selected modes, the highest mode mutually available will
automatically be used. If there is no mode mutually advertised, no link wil l be
achieved.

supported by the local port (those with a “yes” listed in the Local column) can be
advertised. Valid values are Enabled (the mode is supported and will be
advertised), Disabled (the mode is supported but will not be advertised), and
“---” (the mode is not supported).

Local

Indicates whether the operational mode listed in the far right column of the list
box is supported by the local port.

Remote

Indicates whether the operational mode listed in the far right column of the list
box is supported by the remote port.

Auto Negotiate Technology

This column lists possible opera tional modes.

Setting Advertised Abilities for Auto Negotiation

You can determine which operational mode supported by the local port will be

or more interfaces directly to another interface — essentially mirroring the traffic
at the “redirect” interface. This feature is useful in that it allows you to use an
external analyzer on the “redirect” port to analyze data, without disturbing the
normal switching operations at the original source ports. The Port Redirector
window displays the interface remap table and allows you to add new entries to
and delete existing entries from this table. When you set a source port to redirect
to a destination port, the destination port will transmit out all packets received or
transmitted on the source port.

Priority Configuration

The MultiSwitch 700 modules support priority packet forwarding. Priority packet
forwarding lets you designate certain packets to be of higher importance than
others, thereby allowing for the forwarding of these packets before packets of

lower priority. This function ality is essential for time-critical applications — such
as real-time video — on shared networks.

NOTE

The Priority Configuration me nu option will only appear in the Device menu for
modules that respond to any of NetSight Element Manager’s queries to the following

OIDs: ctPriorityExtPortStatus, ctPriorityExtMaxNumMACEntries, or
ctPriorityExtNumPktTypeEntries. If your module’s firmware does not respond to

these queries, contact the Global Call Center for firmware upgrade information.

Frame priority is enabled by the “tagging” of MAC frames so that they are given a
priority designation when they are forwarded by the MultiSwitch 700 module —
which is a tag-aware switch (i.e., one that adheres to the IEEE P802.1p and IEEE
P802.1q Draft Standards). Tagging a frame is accomplished by adding a Tag
Header to a frame immediately f ollowing its original Destination and Source
MAC address fields (and any r outing fields, if pre sent), and then r ecomputing the
Frame Check Sequence (FCS) appropriately. On receiving such a frame, a
tag-aware switch will read the priority from the tagged portion of the frame,
remove the Tag Header, recompute the FCS, and then direct it to its appropriate
transmission queue.

There are eight priority levels — indicated 0 through 7— available to designate
user priority. Frames tagged with a 0 represent the lowest priority level (or
normal) traffic, and frames tagged with a 7 indicate the highest priority level
traffic.

The MultiSwitch 700 module itself suppo rts two transmission queues: one that is
for 0 or normal priority traffic (o r any non-tagged traf fic), and a second queue that
is reserved for frames that have been tagged with a priority level of 1 or higher.
On receiving any priority-tagged frames, the Mult iSwitch 700 will forward them
out of the high priority queue before forwarding any frames in the normal

2-48 Managing the Module

The MultiSwitch 700 Device View

priority queue. However, the MultiSwitch 700 will tag outgoing frames with the
full range of eight priority levels, so that upon reception, a device that supports
the entire range of priority queuing will forward the frame appropriately.

You can use NetSight Element Manager to configure the criteria that determine
the priority in which frames will be queued for transmission by your MultiSwitch

700 module. Several different criteria can be used to determine a frame’s
transmission queue order:

• The module and port at which the frame was received.

• The destination and/or source MAC address associated with the frame.

• A combination of destination and/or source MAC address and the frame’s

protocol type.

• The frame’s protocol type.
When you configure the transmission queue for a specific frame, an entry is made

in one of three priority tables maintained by the MultiSwitch 700 module. These
tables are used to determine which transmit queue to use — normal priority or
high priority — when forwarding frames.

•The ctPriorityExtPortTable maintains priority entries based on a frame’s receive

port.

•The ctPriorityExtMACT able maintains priority entries based on a frame’s

MAC-layer information.

•The ctPriorityExtPktTypeTable maintains priority entries based on the frame’s

protocol type.

The following sections discuss how to use the Port Priority Configuration
window, the MAC Based Priority Configuration window, and the Frame Priority
Configuration window to make entries in these transmit priority tables.

Configuring Priority Queuing Based on Receive Port

You can use the Port Priority Configuration window, Figure 2-21, to determine
packet queuing based solely upon the port at which the packet was received. This
allows you to ensure that a connected user or LAN segment will have priority
when frames that were received on that port are queued for transmission.

NOTES

In the event that an incoming packet received on a designated port already has a priority
associated with it, you can use the ctPriorityExtPortFwdInboundPriority OID to
determine whether the incoming priority should remain intact, or be replaced with the
priority that you have set for the receiving port.

Use the MIB T ools utility suite to set the ctPriorityExtPortFwdInboundPriority OID
to 1 (for the appropriate port instance) if you want the incoming packet to retain its
originally set priority when received by the port; set the OID to 2 if you want the packet to

Normal will cause packets received on that port to be forwarded through the lower priority
queue, and any priority of 1 through 7 will cause the packets to be forwarded through the

priority queues — so the priority that you assign ma y have bearing on how the frame is

Broadcast Suppression

From the Broadcast Statistics and Suppression window, you can monitor
broadcast peak statistics, and suppress the amount of broadcast frames received
on each interface on your MultiSwitch 700 module (thereby protecting your
network from broadcas t storms). Specifically, y ou can monitor the number of
frames each interface is receiving, and set limits on how many of those broadcast
frames will be forwarded to the other interfaces. Once a threshold has been
reached on an interface, broadcast frames will be dropped. From the Broadcast
Statistics and Suppression window, you can set a unique threshold for each
interface on a frames per second basis.

802.1Q draft specification for port-based VLANs.

2-60 Managing the Module

NOTES

NOTE

What Is A VLAN?

The MultiSwitch 700 Device View

For older versions of MultiSwitch 700 firmware, if 802.1Q is to be utilized it is required
that all modules in the chassis be configured to operate in 802.1Q mode. Distributed
Chassis Management ma y not be supported for MultiSwitch 700 modules oper ating in

802.1Q mode. In such cases, it is recommended that all modules installed in the
MultiSwitch 700 chassis be configured via Local Managem ent to operate in Standalone
mode. Contact the Global Technical Assistance Center for firmware upgrade information.

For current versions of MultiSwitch 700 firmware, DELHF-UA modules cannot be
installed in a MultiSwitch 700 that is operating in 802.1Q mode. This will be corrected in
a future version of firmware.

A Virtual Local Area Network (VLAN) is a logical group of devices that function
as a single Local Area Network segment (broadcast domain). Devices comprising
a VLAN may be (physically) widely separated, allowing users located in separate
areas or connected to separate ports to belong to a single VLAN group. Users
assigned to a VLAN can send and receive broadcast and multicast traffic as
though they were all physically connected to a single network segment.
VLAN-capable switches isolate broadcast and multica st tra ffic received from
VLAN groups, and contain broadcasts and multicasts from members of a VLAN
within that group.

What Is An 802.1Q Port-Based VLAN?

Switches that support the pre-standard IEEE 802.1Q draft specification for
port-based VLANs act by classifying frames into VLAN membership. Usually,
VLAN classification is based on tag headers (VLAN tags) in the headers o f data
frames. The tag header is inserted into the frame directly after the Source MAC
address field. A four-byte field in the tag header is used as the VLAN identifier.
These VLAN tags are added to data frames by the switch as the frames are
transmitted and/or received by certain ports, and are later used to make
forwarding decisions by the switch and other 802.1Q switches. In the absence of a
VLAN tag, a frame is assigned VLAN membership according to the VLAN
configuration of the switch port that receives the frame.

About 802.1Q VLAN Configuration and Operation

An 802.1Q VLAN is defined by assigning it a uniqu e identif ica tion number (the
VLAN ID) and an optional name. The VLAN ID is used to identify data frames
that originate from, and are intended for, the ports assigned to the VLAN. Up to
64 VLANs may be created, with VLAN IDs ranging from 2-4094. VLAN ID 1 is
reserved for the Default VLAN.

Managing the Module 2-61

The MultiSwitch 700 Device View

Ports on 802.1Q switches are assigned membership in a VLAN by ass ociating a

VLAN ID with each port on the switch. The VLAN ID is combined with the port’s
identification (e.g., module X port X) to form the Port VLAN ID (PVID).

When 802.1Q mode is initially activated on a device, all ports are associated with the

NOTE

Default VLAN (VLAN ID 1). If a VLAN ID has not been assigned to a particular port
on an 802.1Q switch, any frames received from that port will be classified as belonging to
the Default VLAN.

When 802.1Q is implemented for a MultiSwitch 700 that has a DELHA-UA
installed, each LEC will be represented as an individual port which can be easily
assigned membership in a VLAN.

For current versions of MultiSwitch 700 firmware, the number of LECs supported by the

NOTE

DELHA-UA in 802.1Q mode is limited to 32.

Once VLANs have been configured and activated, all frames with unknown
destination addresses (including broadcast, unknown multicast, and unknown
unicast frames) will be contained within the VLAN of their origin. The switch’s
Filtering Database tracks the associations between MAC addresses, VLAN
eligibilities, and port numbers, and is used to make forwarding decision s f or
frames. All VLANs share a single Spanning Tree.

Ingress List Operation

A port’s ingress list specifies the VLAN with which received frames will be
associated. The switch’s Filtering Database tracks the associations between VLAN
eligibilities, MAC addresses, and port numbers.

Untagged frames received by an 802.1Q switch port are classif ied accor ding to the
VLAN membership of the port that receives the frame.

Tagged frames received by an 802.1Q switch port are classified according to the
VLAN indicated in their tag header. A port may receive a tagged frame that
specifies a VLAN other than the one assigned to the port.

Egress List Operation

Each port’s egress list specifies which VLANs are associated with the port, and
specifies what type of frame (tagged or untagged) to transmit for each particular
VLAN on a port. This information may be statically defined by the user, or
dynamically learned and maintained by the switch’s Filtering Database.

2-62 Managing the Module

The MultiSwitch 700 Device View

If a port receives a tagged frame that specifies a VLAN other than the one

assigned to the port, the switch will dynamically associate that frame’s source
address and VLAN with the port (i.e., add that frame’s VLAN to the receiving
port’s egress list). Dynamically learned VLANs are subject to the same aging rules
as source addresses (e.g., if a tagged frame belonging to a dynamically learned
VLAN is not received by the port within the switch’s aging time, the transmitting
station’s source address and VLAN will be aged out for that port; no unknown
destination frames belonging to the station’s VLA N will be transmitted through
the port until the VLAN is dynamically learned once again). Only tagged frames
can cause the switch to dynamically change a port’s egress list.

802.1Q Port Types

Each 802.1Q switch port is assigned a mode of opera tion. Port types include:

1Q Trunk

If VLAN membership is to apply to users across several switches, ports used to
connect 802.1Q-aware devices ar e configured to use 1Q Trunk mode. In this mode,
all frames (except BPDUs) are transmitted with a tag header included in the
frame, allowing VLAN frames to maintain their VLAN ID across multiple
switches. Any untagged frames received by the port ar e dropped. 1Q Trunk ports
are configured to be members of all VLANs.

1d Trunk

This mode allows a port to transmit to a traditional (802.1d) switch fabric . These
ports transmit only untagged frames, and the switch expects to receive only
untagged traffic through the port. 1d T runk ports are configured to be members of
all VLANs. This mode can be used to share a connection among multiple VLANs
(e.g., sharing a server between two or more separate VLANs).

Hybrid

Hybrid mode (enabled by default) allows a port to receive and transmit both
tagged and untagged frames. In this mode, the port will be a member of its
statically assigned VLAN, as well as any dynamically learned VLANs (remember ,
dynamically learned VLANs are subject to the same aging rules as source
addresses).

Configuring Your 802.1Q VLANS

Before you can define and configure 802.1Q port-based VLANs on your device,
you must activate the device’s 802.1Q operational mode; this operation can be
performed using Local Management or the Mib Tools application. Using Mib
Tools, 802.1Q mode can be activated through the Container Mib’s Logical Entry
Table (cont LogicalEntryTable). When the 802.1Q component is activated, the device
will automatically reset, and begin operatin g in 802.1Q mode.

Managing the Module 2-63

The MultiSwitch 700 Device View

For older versions of MultiSwitch 700 firmware, if 802.1Q is to be utilized it may be

!

CAUTION

required that all modules in the chassis be configured to operate in 802.1Q mode. If you

attempt to activate a MultiSwitch 700 module’s 802.1Q component via the Mib Tools
application, you may lose contact with the rest of the chassis once the device resets. For
this reason, we recommend that Local Management be used to activate 802.1Q mode for
MultiSwitch 700 modules.

Refer to your device’s Local Management documentation for instructions on
activating a device’s 802.1Q operational mode via Local Management. For details
on the Mib Tools application, refer to your Tools Guide.

To set up your 802.1Q port-based VLANs using NetSight Element Manager, you
must first define the desired VLANs using the VLAN Config window
(Figure 2-26), wh ich allows you to assign VLAN IDs an d o ptional VLAN names,
and enable or disable VLANs.

After your VLANs are defined, you may configure the ingress and egress lists for
each port using the VLAN Port Config window (Figure 2-27) and the VLAN
Egress Port Config window (Figure 2-28), respectively.

Enabling and Disabling Ports

When you disable bridging at a port interface, you disconnect that port’s network
from the bridge entirely. The port does not forward any packets, nor does it
participate in Spanning Tree operations. Nodes connected to the network can still
communicate with each other, but they can’t communicate with the bridge or
with other networks connected to the bridge. When you enable bridging for the
interface, the port moves from the Disabled state through the Listening and
Learning states to the Forwarding state; bridge port state color codes will ch ange
accordingly.

You cannot disable a backplane interface from the Device Logical View — since the

NOTE

backplane interfaces do not appear in the port stack. You must use the Device BackPlane
Config View to disable the interfaces to the DLM6C-AA backplane.

To enable or disable bridging for an individual interface:

1. Click on the appropriate port display box to display the port menu.

NOTE

2. Select Enable to enable bridging at the interface, or Disable to disable
bridging. Bridging will now be enabled or disabled across the selected port, as
desired.

To enable or disable bridging for all interfaces installed on the monitored
MultiSwitch 700 module:

1. Click on the module index of interest to display the Module menu.

2. Select Enable Bridge to enable bridging at all installed interfaces, or Disable
Bridge to disable bridging across all interfaces. Bridging will now be enabled
or disabled across the installed interfaces, as desired.

For more information about bridging functions and how to determine the current state of
each bridge port, see the Bridging chapter in the Tools Guide.

The DELHW-UA Device View

Unlike other modular interfaces designed for the MultiSwitch 700 boards, the
DELHW-UA module functions as an independent intelligent device with its own
IP address. As such, it must be managed separately from the MultiSwitch 700
chassis and the board on which it is installed. This section provides information
on launching the DELHW-UA Device View and using its associated functions. For
information on configuring and ma naging the WAN capabilities of the various
port modules available for the DELHW-UA, see Chapter 7.

QuickSET for the DELHW-UA was shipped with your device. This program is designed

NOTE

for point-and-click installation and set-up of DELHW-UA devices. If you launch Chassis
Manager for a DELHW-UA and have QuickSET installed, your Utilities menu will
display a menu pick for launching QuickSET. See your QuickSET for the DELHW-UA
documentation for more information.

Port interface modules available for the DELHW-UA include:
DELDS-UI DDS is Digital Data Services , a digital network that

supports data rates of 56Kbps or 64Kbps. The DDS
service provides users with dedicated, two-way
simultaneous transmission capabilities operating at
transfer rates up to 64 Kbps. This port module comes
with a built-in CSU/DSU.

The MultiSwitch 700 Device View

DELDI-UI The DI (Drop-and-Insert) port interface module pro vides

a T1 interface through a front-panel RJ45 port and
includes a built-in CSU/DSU for direct connection to a
T1 line. The DELDI-UI provides Full T1 or Fractional T1
using 56 or 64 Kbps Time Slots. It also provides a second
Drop-and-Insert interface that allows more than one
device, such as a PBX, to share a single T1 connection.

DELE1-UI This port interface module provides an E1 interface

through a front-panel RJ- 45 port and includes a built-in
CSU/DSU for direct connection to an E1 line. It provides
Full E1 or Fractional E1 using 56 or 64 Kbps Time Slots
with a total throughput of up to 2 Mbps. Time Division
Multiplexing (TDM) allows fo r the channelization of up
to 31 links of a single physica l interface.

and includes a built-in CSU/DSU for direct connection to
a T1 line. The DELT1-UI provides both Full T1 or
Fractional T1 using 56 or 64 Kbps Time Slots, with a total
throughput of up to 1.544 Mbps. Time Division
Multiplexing (TDM) allows for channelization of up to 24
links over a single physical T1/FT1 interface.

DELTD-UI This port interface module provides both a T1 and DDS

interface that allows you to easily switch between the
two interfaces by changing the physical cabling and
reconfiguring the desired interface with either QuickSET
for the DELHW-UA or NetSight Element Manager.

For more information on these port modules, consult the appropriate hardware
documentation or your QuickSET for the DELHW-UA documentation.

To configure the DELDI-UI and DELE1-UI, use the QuickSET application that was
shipped with your device. See your QuickSET for the DELHW-UA documentation for
more information.
