Getting Started with Cisco Network Assistant

OL-6194-07

What Is Network Assistant?

Network Assistant is an application that you can use to manage standalone devices and device

groups—communities and clusters—from anywhere in your intranet. You can perform multiple

configuration tasks without using command-line interface (CLI) commands. You can also apply actions

to multiple devices and ports at the same time for VLAN and quality of service (QoS) settings, inventory

and statistics reports, link and device monitoring, software upgrades, and many other networking

features.

Network Assistant graphical user interface (GUI) provides these views:

• Topology view—shows devices that are in a community, a cluster, or that are eligible to join the

community or cluster, link information between devices, and other connected clusters.

• Front-panel view—allows you to monitor the real-time status of the devices and perform many

configuration tasks. The devices and port LEDs in the view look like the physical devices and the

port LEDs.

A community is a device group that can contain up to 40 connected network devices. Network Assistant

uses the Cisco Discovery Protocol (CDP) automatic discovery capability to find eligible network devices

and to add them to a community. When a network device is added to a community, it becomes a member

device. Network Assistant manages, configures, and monitors each member on an individual basis. Each

member must have an IP address assigned to it.

Most Cisco network devices that have IP addresses, such as routers, switches, and access points, can

belong to a community. For a specific list of network devices, see the release notes. For information on

community limitations, see the “Community Device Limit” section on page 4-2.

You can create a community to manage Cisco cluster-capable devices as well as noncluster-capable

devices in the same logical group, regardless of their physical locations and the software installed on the

devices.With Network Assistant you can create, modify, delete, and manage multiple communities.

A cluster is a device group that can contain up to 16 connected network devices, but they have to be

cluster-capable Catalyst devices. The devices belong exclusively to one cluster; they do not participate

in other clusters. You assign an IP address to a device that will become the command device. The IP

address of the command device is the single point of access that Network Assistant uses to configure,

manage, and monitor the command device and the member devices.

A community offers these benefits that a cluster does not:

• Communities can manage routers, access points, and switches. Clusters can only manage switches.

• The device limit for communities is 40, but the device limit for clusters is 16.

• Network Assistant can communicate securely with every member in a community. In a cluster,

Network Assistant communicates with member devices through the command device, but the

communication is secure only between Network Assistant and the command device. It is not secure

from the command device to member devices.

1-2

OL-6194-07

Chapter 1 What Is Network Assistant?

• If a community member fails, Network Assistant can continue to manage the other members. If a

cluster command device fails, Network Assistant cannot manage the other members of the cluster

unless a cluster standby device has been configured.

• Communities have fewer restrictions than clusters about where members are located and how they

are connected to each other. For more information on cluster member restrictions, see the online

help.

• If candidate devices do not have CDP enabled, you can still create a community and manually add

the devices. Clusters cannot be created unless CDP is enabled on all the candidate devices.

Network Assistant features include front panel and topology views of device groups. See Chapter 2,

“Network Assistant Features,” for more information.

For information on setting up communities, see Chapter 4, “Planning and Creating Communities.”

For information on setting up device clusters, see Chapter 4, “Planning and Creating Clusters” of the

Getting Started with Cisco Network Assistant document, version 1.0.

Front Panel View

When Network Assistant connects to a community or a cluster, you can display the Front Panel view of

your device by clicking the Front Panel on the toolbar or by choosing Monitor > View > Front Panel

on the feature bar. If the device belongs to a community, you see all of the devices that were selected the

last time that the front panel view appeared for that community. If the device is a cluster, you see the

cluster members that were selected the last time that the view was displayed.

By using the Front Panel view, you can

• Drag and re-arrange the devices that appear.

• Select and configure the devices.

• Right-click a port and configure it.

• Select multiple ports, on the same device or on different devices, and configure the ports at the same

time.

Figure 2-2 shows a community with these members: Catalyst 4948, 3750, 3560, 3550, 2960, 2955, and

2950 switches and a Catalyst Express 500 switch.

Chapter 2 Network Assistant Features

Wizards

All wizards contain Wizard in their names on the feature bar. Like guide mode, wizards provide a

step-by-step approach for completing a specific configuration task. Unlike guide mode, wizards do not

prompt you to enter information for all of the feature options. Instead, they prompt you to enter minimal

information and use the default settings of the remaining options to set default configurations.

Wizards are not available for read only access levels. For more information about the read only access

mode, see the “Privilege Levels” section.

Smartports

Network Assistant detects where you have not used Smartports to configure a device connection and

provides this information in the Event Notification window. You can configure the connection either

manually or based on suggestions provided by Network Assistant. Open the Smartports window to either

select a role to apply or use Smartports to suggest a role to apply. See the online help for more

information on Smartports.

Privilege Levels

Network Assistant provides two types of access to configuration options: read write and read only. Your

access type is determined by your privilege level, a number from 1 to 15. Privilege levels correspond to

these access types:

• Level 15 provides read write access.

• Levels 1 to 14 provide read only access. Any options in the Network Assistant windows, feature bar,

toolbar, and popup windows that change the device, community, or cluster configuration are enabled

for read only access. This means that you cannot modify the configuration shown in the windows

started by these items.

By default, Network Assistant tries to log you on with privilege level 15. However, this normally requires

that you pass the authentication with a proper username and password. Lower levels do not generally

impose this requirement.

Note You must have privilege level 15 to access Network Assistant through a TACACS+ or a RADIUS server.

Updates for Network Assistant

Network Assistant can search Cisco.com to see whether new packages are available. Use either of these

actions to request a search:

• Choose Application > Preferences, and use the Preferences window to request an automatic search

every week or every month.

• Choose Application > Application Updates to request an immediate search for updates.

If an update is found, you can install it through Network Assistant.

Online Help

Network Assistant provides comprehensive online help that explains configuration and monitoring tasks.

Sometimes the information in a help topic differs for different devices. In these cases, the right pane of

the Help window contains all the versions of the topic, each labeled with the hostnames of the devices

it applies to.

Online help includes these features:

• Conceptual help that gives background information on networking features

• Window help that gives procedures for performing tasks

• An index of online help topics

• A tab for requesting a search of all the online help topics

• A glossary of terms used in the online help

Installing Cisco Network Assistant

This chapter describes how to install Cisco Network Assistant and how to connect it to a device or an

existing community.

For information about the requirements needed to install Network Assistant, see the Release Notes

at:http://www.cisco.com/en/US/products/ps5931/prod_release_notes_list.html

Installing Network Assistant

To install Network Assistant on your PC, follow these steps:

1. Go to this web address: http://www.cisco.com/go/NetworkAssistant.

You must be a registered Cisco.com user to access this site. You do not need any other access

privileges.

2. Find the Network Assistant installer file, cna-windows-k9-installer-5-0-en.exe.

3. Download the Network Assistant installer, and run it. (You can run it directly from the web if

your browser offers this choice.)

When you run the installer, follow the displayed instructions. In the final panel, click Finish to

complete the Network Assistant installation.

Note Network Assistant is free. There is no charge to download, install, or use it.

Starting Network Assistant

After you install Network Assistant, you will see its icon on your desktop, a Network Assistant shortcut

under the Start menu, and a Network Assistant entry under Start > Programs. When you click any of

these, you see a partial Network Assistant GUI and the Connect window.

In disconnect mode, Network Assistant is not connected to a device or a community; it cannot manage

a standalone device, a community, or the command device of a cluster. Its menu bar and toolbar support

only the tasks that customize Network Assistant itself. The feature bar, which usually lists device

features, is empty.

Getting Started with Cisco Network Assistant

OL-6194-07

Chapter 3 Installing Cisco Network Assistant

Connecting to Network Assistant

Use the Connect window in Network Assistant to connect to a community or cluster. Figure 3-1.shows

the Connect window.

To connect Network Assistant to a device:

Step 1 From the Connect window, enter the IP address of the device.

• For an existing community, select its name from the pull-down menu. For an existing cluster, select

the IP address.

When you select a community, you can also set the access mode and access level. If you do not set

the access mode before connecting to the community, Network Assistant applies the read/write

access mode to all the devices in the community.

• For HTTP and Access Mode options, click the Options button.

–

In the HTTP protocol field, select HTTP or HTTPS. To communicate with a clusterered or a

standalone device, use HTTPS (secure HTTP) instead of HTTP.

–

Select an HTTP port. Use an HTTP port other than 80 on cluster command devices or standalone

devices.

–

Select an access mode. Read-only access mode is the default.

–

Click OK to return to the Connect Window.

• You can also use this window to connect to a new community. For instructions on how to use the

Connect to a new community option to create a community, see the “Creating a Community”

section on page 4-3.

Note For information about using the HTTPS and HTTP options in a community, see the “Communication

Protocols” section on page 4-3.

Because Catalyst 4500 series switches ship with HTTP and HTTPS disabled by default, you must enable

them as needed. HTTPS v3.0 is supported in Cisco IOS 12.2(25)SG cryptographic versions and later.

Figure 3-1 Connect Window

Step 2 Click Connect.

When you click Connect, you are either connected to the community directly, or you are prompted for

a username and password and then connected. When you connect to a cluster, Network Assistant asks if

you want to convert the cluster to a community. For more information on converting a cluster to a

community, see the “Converting a Cluster to a Community” section on page 4-4.

Chapter 3 Installing Cisco Network Assistant

Connecting to Network Assistant

When the connection occurs, the Network Assistant window is in connect mode. The toolbar adds icons

that represent device features. Similarly, the feature bar fills with menus that list the device features that

Network Assistant manages.

Event Notification

Network Assistant informs you of events that it detects by putting an event icon on the status bar and

under devices in the Topology view. Clicking an event icon opens a window that describes the event and,

whenever possible, connects you to the windows where you can take the needed actions.

Planning and Creating Communities

This chapter provides the concepts and procedures for planning and creating communities by using

Network Assistant. It contains these sections:

• Planning a Community, page 4-1

• Creating a Community, page 4-3

For information about using Network Assistant to configure communities, see the online help.

Planning a Community

This section describes the guidelines, requirements, and caveats that you should understand before you

create a community.

Candidate and Member Characteristics

Candidates are network devices that have IP addresses but that have not been added to a community.

Members are network devices that have been added to a community.

To join a community, a candidate must meet these requirements:

• It has an IP address.

• It has HTTP or HTTPS enabled on the default ports.

Note You cannot add clusters to a community. You can add cluster members individually.

If you add a cluster command device to a community, the other members of the cluster are not

added automatically. To manage the cluster members, you must add them individually to the

community.

If you add a Catalyst 3750 switch stack master to a community, the individual stack members

are automatically added to the community, even though the stack members do not appear in the

Modify Community or Discover windows. However, when you connect to the community, the

stack members do appear in the Front Panel and Topology views.

4-2

Getting Started with Cisco Network Assistant

OL-6194-07

Chapter 4 Planning and Creating Communities

Planning a Community

Community Device Limit

The combined number of Catalyst switches, Cisco access routers, and PIX firewalls in a community cannot

exceed 40. There are no limits on individual device types. There is no limit on the number of Cisco Aironet

Access Points.

Note Even though the devices in a Catalyst 3750 switch stack function as a single switch, they count

as individual switches against the combined limit and individual device limits.

If the limit of 40 devices is exceeded, you cannot manage a community. You need to remove devices so

that the total is not more than 40.

There is no limit to the number of communities that Network Assistant can manage.

Automatic Discovery of Candidates and Members

Beginning with the IP address for a starting device and the port numbers for the HTTPS and HTTP

protocols, Network Assistant uses CDP to compile a list of community candidates that are within

four CDP hops of the starting device. Network Assistant can discover candidate and member devices

across multiple networks and VLANs if they have valid IP addresses. See the “Candidate and Member

Characteristics” section on page 4-1 for a list of requirements that network devices must meet in order

to be discovered.

Note Do not disable CDP on candidates, members, or any network devices that you might want Network

Assistant to discover.

You can edit the list of discovered devices to fit your needs and to add them to the community. If Network

Assistant does not discover a network device, you can manually add the device.

For instructions on adding discovered devices to a community or manually adding devices to a

community, see the “Manually Adding Members” section on page 4-4.

Community Names

When you create a community, Network Assistant requires that you assign a name to it. The name can

contain up to 64 alphanumeric characters and is not case sensitive.

Note When you select a name in the Connect window and a cluster and a community share that name, Network

Assistant connects to the community.

Hostnames

You do not need to assign a hostname to a community member, and Network Assistant does not assign

one by default. However, Cisco IOS assigns the hostname Switch to switches without a hostname.

Therefore, you might want to assign hostnames to switches to avoid confusing them.

4-3

Getting Started with Cisco Network Assistant

OL-6194-07

Chapter 4 Planning and Creating Communities

Creating a Community

Passwords

When connecting to a community, Network Assistant prompts you for each unique password that has

already been assigned for members of the community. Network Assistant attempts to use these

passwords to connect to other devices. You are prompted for a password only if the previously entered

password does not work for a device.

For example, if a community has ten members, and five members share one password and the other five

share a different password, Network Assistant prompts you twice, once for each password. Network

Assistant does not save the passwords to your PC, so it prompts you for the passwords each time that

you attempt to connect to a community.

Communication Protocols

Network Assistant uses HTTPS and HTTP to communicate with community members. It first tries to use

HTTPS when using CDP to discover neighboring devices and when devices are added manually. If

HTTPS fails, it tries again with HTTP.

The HTTPS port is fixed at 443; the HTTP port defaults to 80. You can specify a different HTTP port

when you create a community. Afterward, you use the HTTP Port window to change the HTTP port. The

port settings for both HTTPS and HTTP must be the same for all the members of a community.

Community Information

Network Assistant saves all individual device information, such as the IP address, the hostname, and the

communication protocol, to your local PC. When Network Assistant connects to a community, it uses

the locally saved data to rediscover the member devices.

If you try to use a different PC to manage an existing community, none of the member device information

is available. You need to create the community again and add the same member devices.

Creating a Community

There are three ways to create a community:

• By discovering candidates that you can add to the community

• By manually adding devices

• By using the Cluster Conversion Wizard to convert a cluster into a community

You should verify that the community contains the devices that you think it contains. This section tells

you how to perform these tasks.

Discovering and Adding Devices

Follow these steps to compile a list of candidate devices and to add them to a community:

1. Start Network Assistant, and select Connect to a new community in the Connect window. Click

Connect.

2. In the Create Community window, enter a name for the community.

Creating a Community

3. Click the Advanced button if you want to set an HTTP port other than 80, the default port. Enter the

HTTP port number that you want to use. Click OK.

4. Enter the IP address for the starting device, and click Discover Neighbors.

5. In the Devices Found list, select candidate devices that you want to remove.

a. To remove more than one candidate, press Ctrl and make your choices, or press Shift and

choose the first and last device in a range.

b. Click Remove.

6. Click Add All To Community to add the remaining devices in the list to the community.

Manually Adding Members

Network Assistant provides two ways to manually add devices to a community.

1. In the Create Community window, enter the IP address for the device that you want to add.

2. Click Add to Community.

The second way to manually add a device uses the Topology view:

1. If the Topology view does not appear, choose View > Topology from the feature bar.

2. Right-click a candidate icon, and select Add to Community.

Candidate device labels are cyan; member labels are green.

Converting a Cluster to a Community

The Cluster Conversion Wizard creates a community by using the information available for the cluster.

The wizard prompts you to enter an IP address and from the pulldown lists to select an interface name

and subnet mask for each device that does not have them. Network Assistant does not delete the cluster

upon creating the community.

There are two ways to start the Cluster Conversion Wizard. When you connect to a cluster command

device, the wizard starts and asks if you want to convert the cluster into a community. You can also start

the wizard from the feature bar by choosing Configure > Cluster > Cluster Conversion Wizard.

Verifying a Community

Follow these steps to verify the community:

1. Choose Monitor > View > Topology to display the Topology view.

2. Choose Monitor > Reports > Inventory to display an inventory of the devices in the community.

This summary includes device model numbers, serial numbers, software versions, IP information,

and location.

3. Choose Monitor > View > Front Panel to display the Front Panel view.

Configuring Your Switch for Network Assistant

This section describes how to configure your switch for Network Assistant. It includes these sections:

• Minimum Configuration to Access Catalyst 4500 from Network Assistant, page A-2

• Additional Configuration Required to Manage a Community, page A-3

• Additional Configuration Required to Manage a Cluster, page A-3

Minimum Configuration to Access Catalyst 4500 from Network Assistant

If you use the default configuration, access the Catalyst 4500 series switch, and enter the ip http server

(for HTTP) or the ip http secure-server (for HTTPS) global configuration command:

1. You need to set an IP address in each switch for community device discovery and for the cluster

commander.

2. Port number on the Network Assistant and the Catalyst 4500 series switch must match.

3. You can only change this value for a cluster of devices. Port number on the Network Assistant and on the

Catalyst 4500 series switch must match. Value can be changed to any non-default number above 1024.

4. Required for Network Assistant to access the device.

5. Enabled only if you want to manage a cluster of devices.

Command Purpose

Step 1 Switch# configure terminal Enter global configuration mode.

Step 2 Switch(config)# ip http server

Switch(config)# ip domain-name
