What is ATM and VLAN Management?
OVERVIEW
This chapter introduces you to the ATM and VLAN Management
application. The following topics are discussed:
■ What is ATM and VLAN Management?
■ ATM and VLAN Management Maps
■ ATM and VLAN Management Tools
■ ATM and VLAN Management Assistants
The Transc end ATM and VLAN Management application is a network
management software product used for managing switched virtual
networks and ATM infrastructures. With this application, you can
configure, controll and monitor loc atio n- indep end ent virt u al work gr o ups
that are created using different technologies based on ATM, Ethernet,
Fast Ethernet and FDDI.
ATM and VLAN
Management
Components
The A TM and VLAN Ma nagement app licati on manages vir tual LAN s on all
3Coms ATM and non-ATM switches.You can create virtual LANs with
either ATM-based (LAN Emulation) or non ATM-based
(Encapsulation/Tagging) methods.
The ATM and VLAN Management application allows you to view and
manage the network at vari ous layers of logical and physical layers.
Specialized inte rr el at ed co mpo nents are used to ma nag e each ab str acted
layer. This application provides the network manager with a global view
of the status, configuration, performance, and utilization of the ATM
infrastructure, LAN Emulation services, and network virtual LANs.
The ATM and VLAN Management application i s composed of the
following product co m p on e nts:
■ Maps
1-2 CHAPTER 1: ATM AND VLAN MANAGEMENT OVERVIEW
■ Tools
■ Assistants or Wizards
These components are network models that represent network
information, based on the physical and logical structure of the network.
The maps repr esent t he net work mod el an d stat us inf ormat ion. Di f ferent
maps are available for the different logical and physic al views.
The tools perform various network management tasks and functions.
The ATM and VLAN Management tools can be launched from the
application or from within a web browser tool (locally or from a remote
location). If you launch the tools from within a web browser, only the
tasks that do not require any additional configuration assi stants can be
performed. VLAN moves are allowed fr om the web interface.
The Assistants or Wizards configu re and perform specific actions on the
network devices in th e manage ment maps. ATM and VLAN Management
Assistants are launched from maps or tools.
Supported platforms The ATM and VLAN Management application runs on all platforms
supported by OpneView Windows (OVW), NetView, and SunNet
Manager.
Functions of ATM and
VLAN Management
You must upgrade Netscape to version 4.03 with JDK1.1 support.
Upgrading to Nets cape version 4.03 is insufficient to run the web-based
A TM VLAN software. Y o u must have the JDK 1.1 support for the software
to run properly.
You can dowload JDK software from the JAVA site currently at the
following address:
http://developer.netscape.com/software/index.html?co
ntent=jdk/download.html
The ATM and VLAN Management application is identical for all platform
environments. You can perform network management oper ations and
functions from any workstation.
The ATM and VLAN Management application provides the following
functions:

ATM and VLAN Management Maps
ATM Device Manager
Map
The ATM and VLAN Management application includes the following
maps:
■ ATM Device Manager map
■ ATM Network map
■ LAN Emulation map
■ Virtual LAN map
■ VLAN Policy map
■ Gigabit Network map
The ATM Device Manager map (see Figure 1-1), shows the physical
topology of the entire switched infrastructure in a single flat topology
map. The ATM Device Manager map provides the quickest access to all
ATM devices on the network. You also can select the devices graphic

You can display a device-oriented view including device front panels,
device statistics and device parameters using the ATM Device Manager
menus and submaps.

ATM Network Map The ATM Network map (see Figure 1-4) allows you to perform
management tasks on diff erent ATM devices,depend in g on thei r physi cal
connectivity. The ATM Network window displays a hierar chical switching
backbone of the network . Each ic on re pr esents a swi tching do main, such
as a central high-speed CoreBuilder ATM switch module that is connected

to various ATM devices, such as a SuperStack II switch 2700 and other
CoreBuilder modules. The line s connecting the ATM switching domains
indicate the P-NNI (Private Netw ork to Network Interface) links between
them.
The ATM Network Map provides:
■ Displayof the connectivity between ATM switches (CoreBuilder 7000)
and ATM edge devices and end stations (SuperStack II Switch
2700/1000/3000, CoreBuilder 2500, CoreBuilder 5000, NETBuilder,
ATM adapter)
■ Identification of port numbers on the links between switches
■ Statistics on tr affic to a nd from different devices and t hrough specific
device ports
■ Tracing and modification of virtual circuits betw een devices
■ Selection of ATM end points to perform ATM path tracing

Virtual LANs Map
The Virtual LANs Map (see Figure 1-10), is used to manage the logical
connectivity of the end -user through the Virtual LANs. The Virtual LANs
maps provide view s of the connectivity between Ethernet/ATM ports to
the different VLANs. You use the Virtual LANs Map to manage ATM LAN
Emulation-based as well as legacy LAN encapsulated or tagged-based
VLANs.
The features of the Virtual LANs Map include:
■ Re-configuration of VLANs
■ Moving segments between VLANs, using simple mouse actions
■ Clarification of VLANs to physical ports ma p pin g
