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.

gathering etc. can be performed using this interface.

The Transcend Topology Browser is comprised of two sections. The
section on the left is the Component View and the section on the right is
the Topology View.

ATM and VLAN Management Tools 1-25

The Topology View shows the layer 2 physical topology of la rge switch ed
infrastructures (net works with more than 500 Switches) in a single
hierarchy. For example, all the devices, such as ATM switches,
Fast-Ethernet Switches, and there corresponding edge devices, are
mapped.

The tree type Component View is hot linked to the Topology View and
allows for quick selection of infrastructure compone nts th at a re
dynamically highlighted on the topology map. This feature allows you to
select an entry in the Component View, and view the highlight ed
component in the Topology View using the Cross Reference icon.

For example, if you select a switch or an edge device fro m the ATMvLAN
Devices branch in the Component View, the selected switch is
highlighted in the Topology View. If you select a VLAN entry in the VLA N
branch, all the switches that belong to the VLAN are highlighted

The Component View has two windows for displaying the components.
The two windows allow for opening and viewing different branches at
the same time. For example, in the top window, a VLAN branch may be
opened displaying all t he VLANs. In the bottom window, a specific VLAN
branch may be selected, and the segments within the VLAN displayed.
When performing VLAN moves, segments may be selected from one
window (top or source), and the target VLAN may be selected from the
other window (bottom).

T raffic pattern overlays are planned for the future in the Component View
as the Topology View will be hot linked to the Bandwidth Tool.

The topology map includ es the following icons:

■ Zoom Out - This tool is used to magnify the topology map.

■ Zoom In - This tool is used to reduce the topology map.

■ Select Area - This t ool is used to select an area of the topology map.

Use this tool by cli cking on the icon and then defining a n area ( square)
on the topology map. The selected area is resized to fit the topology
map window. When used in conj unction with the Pan tool, you can
resize the selected area by resizing one of the rectangles handles using
MB1.

■ Pan - The tool opens up a display window that allows you to pan the

entire network.

1-26 CHAPTER 1: ATM AND VLAN MANAGEMENT OVERVIEW

■ Refresh - This tool updates the network status.

The Topology Tool includes the fo llowing features:

■ Rearrange - You can rearrange the components for display by

dragging them on the Component View to the desired location.

■ Search - This feature allows you to enter an IP address and locate the

device on the Topology View.

■ Highlight - The Component View, in conjunction with the Cross

Reference Tool highlights the component selected in the Topology
View.

■ Identify - Use this feature to identify the device IP Address and its

name. You use the i dentify feature by clicking with the right mouse
button on the Topology View.

■ Display Front Panel - The feature is the same as the Zoom Physical

feature in the ATM and VLAN Management application. You can
display device front panels by double clicking on the device in the
Topology View.

The Component View reflects the status of all the components that are
being actively p olled by a di stribu ted po lli ng agen t (me dp). For customer s
that do not want to use the platform maps, HPOV, Netview or SunNet
Manager, the Transcend Topology Browser may be us ed as the main
console.

For distributed viewing capability, the Topology Tool can be
accessed via a web browser.

You must upgrade Netscape to Version 4.03 with JDK1.1 support.
Upgrading to Netscape 4.03 is insufficient to run the web-based ATM
VLAN software. You must have the JDK 1.1 support for the software to
run properly.

display the percentage of traffic on the network using the NNIx Maps.
The Bandwidth Tool is organized based on enhanced Interswitch Interim
Signalling Protocol (IISP) address hierarchy. This tool is used to log the
traffic information to a file, so that historical network-wide NNI link level
data can be gathered and displayed. The Bandwidth tool is also used to
graphically display errors on NNI links across the networks.

The Locator Tool, (see Figure 1-21) functions as a search and modification
tool to the ATM and VLAN application’s databases. These databases are
built using other to ols. For example , the MAC VDB data base is built using
the Build UDB Tool. The Manual Discovery database is built using the
Manual Discovery Setup. See “Configuring Manual Device Disco very” on
page 4-1. The VL AN Aliases a nd Colors d atabase ar e bu ilt using t he VLAN

The Locator Tool uses a search string that is color-coded and displays all
other parameters for the selected string in the bottom portion of the
dialog box.

Figure 1-21 The Locator Tool
Users Tool

The Users T ool opens the Build UDB tool, see Figure 1-22, is used to build
a parameter database for st oring all the information related to MAC
addresses in the network. The Users Tool performs an inventory of the
existing network, automatically discovers the MAC addresses that exist
and their respective locations (device, port) and their current VLAN
mapping. The parameter database populated by the Build UDB tool may
be modified manually to change VLAN mapping. Use the Locator Tool to
edit the database. Devices that enforce the MAC based Automatic VLAN
configuration policy will query this database to resolve MAC address to
VLAN mapping.

Configuring SNMP SmartAgents on Devices

Figure 2-1 NMSetup Step 1

For a detailed description of the NMSetup Tool see page 1-43.

The NMS performs physical l ayer manage ment usi ng the SNMP. The NMS
polls agents for status, configurati on and ne two rk traffic informatio n .

The first step in initializing the network for management is to configure
the SNMP SmartAgents in the 3Com ATM and VLAN devices.

To configure the SNMP SmartAgents on Devices:

1 Determine the manage ment IP subne t and IP addr esses to be used for the

ATM devices and the Transcend ATM and VLAN Manager Stat ion.

2 Configure the IP address and default gateway in each ATM switch unit.

See the device Installation and Setup Guide for the swit ches you are
using.

It is recommended that all the ATM and VLAN devices be configured as
members of the same subnet as the Network Management Station

(NMS). This allows the N MS to access t hese d evi ces dir e ctly over th e ATM
network instead of goin g across router s.

3 Configure the IP address, and default gateway of Bridge 0 in each of the

edge device units. See the device Installation and Setup Guide for the

CAUTION: Do not start the ATM and VLAN Network Manager until all
the ATM and VLAN devices have been discovered and appear in the IP
Map of the management platform.

Setting Up for

Distributed Polling

Polling in SNMP management is the activity whereby the NMS
interrogates/polls individual nodes on the networ k for their current
status. It is one if the most important sources of network management
control for traffic on the network.

The ATM and VLAN Management application ma intains the status and
state of all the logical and physical components of the network. You
cannot rely on the platform poller alone (such as HPOV SNMP Poller)
which only maintains the “ping” status of the network when using the
application. T he ATM and VLAN Management application us es a
platform-independent poller call ed the Mediation Poller or Medp to
actively maintain the status of all the components it is monitoring.

Starting the Poller Locally

In small networks cons isting of le ss than a 100 n etwork devi ces (ATM and
Non-ATM switches), a single central poller is adequate for polling the
network and maint aining the stat e of t he logi cal an d physic al net work. In
these types of netwo rks, the Me diation Pol ler can r eside on t he NMS. The
default configuration installs the mediation poller when the ATM and
VLAN Management application is installed. The poller is initialized and
activated along with ot her network management pla tform processes.

Starting the Poller on Multiple Distributed Machines

When using the application to manage a larger network, consisting of
many network devices, or when the network is managed over a wide
area, it is possible to distribute the polling.

Distributing polling onto more than one machine has several advantages.
The advantages are:

■ Localizes polling in remote sites so as not to send polling traffic on

WAN links.

■ Distributes the polling load onto several machines to get better polling

performance and SNMP traffic distribution.

■ Frees up CPU resources on the central management station, thus

providing better cons ol e pe rfo rm a nc e .

Configuring SNMP SmartAgents on Devices 2-5

The following ste ps mu st be foll o w ed wh e n in sta lling distributed po ll ers:

1 Install the Transcend ATM and VLAN Management application on the

central machine on top of an open management platform such a HPOV.
In a distributed polling environment, this machine is the Central Viewing
Station or Central Ma na gement Console

or
install the Transcend ATM and VLAN Management application as a

stand-alone application, on other U nix machines (Solaris, AIX or HPUX).
An open management platform is not requ ired. In a distributed polling
environment these machines are referred to as polling stations or pollers.
These machines do not require an open management platform such as
HPOV installed on them.

2 On the polling station, start the polling process:

a Change Directory to /usr/NCDNMS/make/
b Execute the file “medp.”

It is advised to include these steps in the boot configuration of the polling
station so that the y ar e executed a utomaticall y when th e polling station i s
booted up.

3 Configure the ATM and VLAN Management a pplication on the central

management station to recognize the distri buted pollers and delegate
polling responsibilities to each poller.

Before starting the application , ed it the fol lo w in g file :
/usr/NCDNMS/runtim e/cn f/m ed ia tio n d.cnf
Each line in the /usr/NCDN M S/ run ti me / cn f/m e d iatio n d. c nf co n s ists of

three fields, each separated by a colon. The upper lines in the files take
priority over the lower lines.

This customization of this file can be performed using the NMS
Setup Wizard.

The first field is the range of the IP addresses tha t devices will be polled
from. The second field is the poller IP address. The third field represents
the socket port number communication port. The default number for the
socket port is 1161

Device Configuration for VLANs in ATM Networks 2-7

Device Configuration for VLANs in ATM Networks

CoreBuilder 7000

ATM Switch

Configuration

A Virtual LAN is logical port group spanning a single device or multiple
devices on a network forming a single broadcast or flooding domain.
When LAN Emulation protocols are used to create broad c ast domains
over ATM-based infrastructures, these broadcast domains are also
commonly known as Emulated LANs or ELANs. Each Emulated LAN is
serviced by a single LE S (LAN Emulat ion Serv er) and single BUS (Br oad cast
Unknown Server). Endstations or network devices that join a common
Emulated LAN are said to be in a single ELAN or VLAN . These endsta tions
communicate with the LAN Emulati on Servi ces (LES/B US) via anot her LAN
Emulation entity called a LAN Emulation Client (LEC).

To build and manage ATM/LAN Emulation-based Virtual LANs, the LAN
Emulation Services and Clients must first be manually configured into
their respective default states via device consoles or a local management
interface. Only after they are configured, can you use the ATM and VLAN
Management application to manage and manipulate the environment.

The CoreBuilder 7000 ATM Switch supports the LAN Emulation Services
(LES/BUS/LECS). Depending on the number of Emulated LANs that need
to be created, LANE services must be enabled on one or more
CoreBuilder 7000 switches in the networ k. You can use the CB7000 Fast
Setup tool to configure the CB7000 through the ATMvLAN Toolbar. See
“The CB7000 Fast Setup Tool” on page 2-8.

The following guidelines should be followed when enabling LAN
Emulation Services on the CoreBuilder 7000.

1 When there are multiple CoreBuilder 7000s, the LAN Emulation Serv ices

must be distributed amongst all the core switches.
For example, if 10 Emulated LANS are require d and the network is

comprised of 5 Cor eBuilde r 7000 s in the cor e of the net work, you sh ould
distribute the LANE Services on all the core switches.

All LANE services should be enabled on all the core switches. Since each
CoreBuilder 7000 suppo rts 16 LES/BU S pairs, so me of these LES/BUS pai rs
may be configure d as prim ary LAN E server s of an ELAN and the ot he rs as
backup LANE Servers for the primary LES/BUS pair. See Chapter 4.

2 When there are multiple CoreBuilder 7000s, the LAN Emulation

Configuration Server (LECS) may be enabled on multiple switches. Up to
5 LECSs may be configured as active LECSs in the netw ork . You should
enable LECSs on some of the core switches in the network.

2-8 CHAPTER 2: CONFIGURING AND LAUNCHING THE ATM AND VLAN MANAGER

3 The Network Management Station should be connected directly to the

switch running the primary LECS. This will ensure that the NMS always
has access to the LECS so that it can enable the backup LES when the
primary LES fails. See “Description of LES/BUS Redundancy” on page
4-10.

This CB700 Fast Setup icon opens a wizard that allo ws to configure the
CoreBuilder 7000.

To use the Fast Setup Tool.
Click on the FSetup icon in the ATMvLAN Toolbar. Step by step

procedures are displayed that allow you to configure the CB7000.

ATM Edge Device

Configuration

A TM edge devices such as Super Stack II Switch 2700, CoreBuilder 7200,
Switch 1000, CoreBuilder 5000 Switch Modules etc., provide the legacy
LAN-to- ATM integration. Some of these edge devices need to be
pre-configured to enable the LAN Emulation Clients within them.
Typically, this involves configuring t he local bridge groups within the
devices and their corresponding LECs. Please refer to the appropriate
device configuration manuals for information on VLAN/ELAN
configuration of these devices.

Device Configuration for VLANS in Non-ATM Networks 2-9

Device Configuration for VLANS in Non-ATM Networks

Virtual LANs in non- ATM (Fast Ethernet) environments are created by
using Layer 2 encap sul at ion o r Tagging as a means to create broad cast or
flooding domains. Ports that are common to multiple Virtual LANs are
known as Virtual LAN Trunks (VLT). Switch 1000/3000s and Core Builder
5000 Fast Module s supp o rt this fe ature. VLTs m us t be co n fig ured on the
switches prior to using the ATM and VLAN application to manipulate the
VLT-based VLANS. Please refer to the Switch 1000/3000/CoreBuilder
5000 Fast Module configuration manuals for information on VLT-based
Virtual LANs.

Discover devices via the HP OpenVi ew IP Map

Ping devices if they don’t appear in the IP map. Start the ATM and VLAN
Management applicat ion only after all the devices are discovered by
HPOV and are displa yed in the IP map.

If you encounter problems discovering devices from the HPOV platform
database, or if you want to setup the applicat ion to ignore t he platform

discovery database, you can manually discover devices using the Manual
Device Discovery Assistant. See “Using the Manual Device Discovery
Assistant” on page 4-2.

Verify that your network is up and running.

As the application begins, it is modeling (understanding the logical and
physical structure)

the ATMvLAN network. The length of this process
depends on the size of the net work. For larger networks, it may take up
to 15 minutes for your maps to be activated.

To check that the network modeling process is complete open the LAN
Emulation Map and verify that all of the icon colo rs ha v e cha n ge d from
blue to yellow, green or red.

Common Startup Problems

If the root ic ons don’t change color from blue, it may be because either
the MEDP or PDP task s are not runn in g .

There ar e two way s to che ck tha t the ME DP and PD P process are r unnin g
on OVW or NetView:

■ use the ovstatus command

■ use the ps command

The ps command is used for the Su nNet Manager to check if the
processes are running.

Customize the VLAN colors and aliases.

Customizing the VLAN aliases and colors enables the ATMvLAN device
view windows to show what VLANS each port is assigned to. If you do

in files stored in the C:\usr\TranscendNT\ATMvLAN\runtime\cnf and
C:\usr\TranscendNT\ATMvLAN\runtime\dat directories. These settings
affect various features of the ATM and VLAN Management application
and can make your ATM network easier to manage. Once changed, the
application needs to be unloaded and reloaded for them to be applied.

■ Edge Device connectivity at User-Network Interface (UNI) level

■ Virtual Channels across NNI and UNI Interfaces.

■ List the ATM address space of the Network

The ATM Network Map displays the most up to date physical connectivity
of the network. If a link between two switches fails, the map deletes the
link from the ATM Network Map instead of displaying the link in the
critical (red) state.

To det ect unexpected changes in the network configurati on, you can
maintain snapshots of windows of interest. These snapshots may be used
as a baseline for comparison, for example, of detecting a link fault. Link
faults can cause a link icon to disappear from a window.

The snapshot facility is located in the Map menu of HPOV.
