Configuring Switches with Web-Based Tools
This chapter describes how to install and configure the Network Assistant on the Catalyst 4500 (or Catalyst 4948) series switch. (Heretofore, the term Catalyst 4500 series switch will be used to refer to both switch types.) It also describes how to create and manage a group of devices or Catalyst 4500 series switches using communities or clusters.
Network Assistant is a Windows-based Java application that sends Cisco IOS commands to configure and manage the Catalyst 4500 series switch over HTTP. Network Assistant manages standalone devices or groups of devices or switches (in communities or clusters) from anywhere in your intranet. Using Network Assistant, you can perform multiple configuration tasks without having to remember commands.
This chapter also describes how to install and configure the Embedded CiscoView network management system to provide a graphical representation of a Catalyst 4500 series switch and to provide a GUI-based management and configuration interface.

Installing Network Assistant
To install Network Assistant on your workstation, follow these steps:
Step 1 Go to this Web address: http://www.cisco.com/go/NetworkAssistant/
You must be a registered Cisco.com user as a guest, but you need no access privileges.
Step 2 Click on Free Download.
Step 3 Find the latest version of the Network Assistant installer.
Step 4 Download the Network Assistant Installer and install the application. (You can operate the installer directly from the Web if your browser offers this choice.)
Network Assistant is free—there is no charge to download, install, or use it.
When you initiate the installer, follow the displayed instructions. In the final panel, click Finish to complete the installation of Network Assistant.
Getting Started with Network Assistant
If you use the default configuration, access the Catalyst 4500 series switch and enter the ip http server global configuration command:
If you plan to use community, define an IP address on each switch:
If you plan to use clustering, enter the cluster run global configuration command on each device and enter the ip address interface configuration command on the cluster commander:
Launching the Network Assistant
After installing Network Assistant, you will see its icon on your desktop. You will also see a Network Assistant entry under Start > Programs and a Network Assistant executable file in the installation directory. When you select any of these items, two windows will appear: the Network Assistant window, in disconnect mode, and the Connect window.
In disconnect mode, Network Assistant is not connected to any device, and it cannot manage a standalone device or the command device of a cluster. Its menu bar and tool bar support only tasks that customize the Network Assistant itself. The feature bar, which usually lists device features, is empty. Online Help is available in disconnect mode.
Connecting Network Assistant to a Device
To connect the Network Assistant to a device, use the Connect window, shown in. In this window, enter the IP address of the device to which you want to connect. If you are authorized to configure the device and the HTTP port of the device is 80, you can ignore the settings in the Options button.
Note The HTTP port cannot be configured on a Catalyst 4500 series switch running Network Assistant with Release 12.2(20)EWA.
When you click Connect, you either connect to the device directly or you are prompted for a user name and password and then are connected.
When the connection occurs, the Network Assistant window is in the connect mode. The toolbar adds icons that represent device features. The disconnected icon changes to connected.
Similarly, the feature bar fills with menus that list the device features that Network Assistant manages.
Note For complete procedures for using Network Assistant to configure switch communities, refer to
Getting Started with Cisco Network Assistant, available at:
http://www.cisco.com/en/US/products/ps5931/prod_installation_guides_list.html.
Using Community Mode to Manage a Network of Switches
This section describes how to use communities to create and manage Catalyst 4500 series switches (called devices) using the standalone Network Assistant application.
Beginning with Network Assistant 2.0, you can use communities to group the switches in your network. In contrast with clusters (described next), communities do not require a special IOS configuration. The only requirement is that you configure an IP address on each switch. Be aware that management of routers and access points is supported only in communities.
The total number of devices in the community does not exceed 20 total devices (including up to 4 Catalyst 4500 series switches (modular), 16 Catalyst 2900/3500 or Catalyst 4948 switches (non-modular), 2 routers, and 12 access points). When a community has 20 members, the
Add to Community option is not available for that community. In this case, you must remove a member before adding a new one.
This section describes the guidelines, requirements, and caveats that you should understand before you create a community. This section contains the following topics:
•Candidate and Member Characteristics
•Automatic Discovery of Candidates and Members
•Access Modes in Network Assistant
Candidate and Member Characteristics
Candidates are network devices that have IP addresses but 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.
•Cisco Discovery Protocol (CDP) version 2 is enabled (the default) - if you want the device to be autodiscovered.
•It has HTTP enabled.
Note A cluster member can be added to a community, but a cluster cannot.
If the cluster commander is added to a community, the other member devices of the cluster are not added automatically. The cluster members must be added to the community on an individual basis in order to be managed.
Automatic Discovery of Candidates and Members
Beginning with the IP address for a starting device and the port numbers for HTTP protocols, Network Assistant uses CDP to compile a list of community candidates that neighbor the starting device. Network Assistant can discover candidate and member devices across multiple networks and VLANs as long as they have valid IP addresses.
Note By default, Network Assistant in community mode discovers up to 4 hops away.
See the "Candidate and Member Characteristics" section for a list of requirements that network devices must meet in order to be discovered.
Note Do not disable CDP on candidates, members, or on any network devices that you might want Network Assistant to discover.
You can edit the list of discovered devices to fit your needs and add them to the community. As each device is added to the community, its neighbors are discovered and added to the list of candidate devices. If Network Assistant fails to discover a device you can add it manually via the IP management address.
Community Names
When you apply the community configuration information to the list of member devices, Network Assistant requests that you enter a name for the community. You need to assign a name to the community before you can manage it. Network Assistant saves the name to your PC.
The community name can consist of the characters 0-9, a-z and A-Z, with spaces allowed between the characters.
Note You can connect to a cluster only via an IP address. When you select a name it is always for the community.
Host Names
You do not need to assign a host name to a starting device or a community member. However, Cisco recommends it and Network Assistant does not assign one by default. If a discovered device does have a host name, Network Assistant saves it to your PC as identifying information for that device along with its IP address, communication protocol, and designated protocol port.
Passwords
Although you do not need to assign a password to a device if it will become a community member, Cisco recommends that you do so.
Community members can have different passwords.
Communication Protocols
Network Assistant uses the HTTP protocols to communicate with network devices. It attempts communication with HTTP when using CDP to discover candidate devices.
Access Modes in Network Assistant
When Network Assistant is connected to a community or cluster, two access modes are available: read-write and read-only, depending on the password.
Community Information
Network Assistant saves all community configuration information and individual device information such as IP address, host name, and 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 attempt to use a different PC to manage an existing community, the member device information will not be available. You will need to create the community again and add the same member devices.
Adding Devices
There are three ways to add members to a community.
The first uses the Devices Found window on Network Assistant to add devices that you discovered to a new community:
a. In the Devices Found window, select candidate devices that you wish to add.
To add 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 Add.
The second way uses the Modify Community window to add devices to an existing community:
a. Choose Application > Communities to open the Communities window.
b. In the Communities window, select the name of the community to which you would like to add a device, and click Modify.
c. To add a single device manually, enter the IP address for the desired device in the Modify Community window, and click Add.
d. To discover candidate devices, enter the IP address for the starting device, and click Discover.
e. Select a candidate device from the list, click Add, and click OK.
To add more than one candidate, press Ctrl and make your choices, or press Shift and choose the first and last device in a range.
The third way to add a device uses the Topology view:
a. If the Topology view is not displayed, choose View > Topology from the feature bar.
b. Right-click a candidate icon, and select Add to Community.
Candidates are cyan; members are green. To add more than one candidate, press Ctrl and left-click the candidates that you want to add.
When a community has 20 members, the Add to Community option is not available for that community. In this case, you must remove a member before adding a new one.
Note If you are logged into a community and you delete that community from some other CNA instance, then unless you close that community session, you can perform all the configurations through that session. After you close that session (and thereby delete the community), you will not be able to connect to that community.
Converting a Cluster into a Community
The Cluster Conversion wizard helps you convert a cluster into a community. When you complete the conversion, you can immediately manage the device group as a community. The benefits of managing a community is that the communication with the devices in a community is more secure (through multiple passwords) than in a cluster. Moreover, device availability is greater, and the range of devices that can be members is broader.
Note The Cluster Conversion wizard does not alter your cluster definition. This means that you can still manage the devices as a cluster.
To launch the Cluster Conversion Wizard, follow these steps:
Step 1 Start Network Assistant and connect to an existing cluster through its commander IP address.
Step 2 In the feature bar, click Cluster > Cluster Conversion Wizard.
You will see the query "Do you want to convert this cluster to a community?"
Step 3 Select Yes to proceed or No if you want to manually bring up the Cluster Conversion Wizard.
If you select Yes, the Welcome screen appears, providing information about clusters, communities, and their benefits.
Next, a table appears listing the devices in the cluster starting with those that have no IP address and subnet mask. Be aware that all the devices in the cluster must have an IP address and subnet mask to be members of a community.
Note If a device has more than one interface with an IP address and subnet mask, you see more than one interface listed when you click in the cell. You can choose a different interface from the one originally shown.
Step 4 In the IP Address column, enter an IP address for each device that does not have one.
Step 5 In the Subnet Mask column, click in the cell for each device that does not have a subnet mask and select one.
Step 6 Enter a name for the community.
Step 7 Click Finish to begin the conversion.
When the conversion completes, Network Assistant restarts and automatically connects to the newly created community.
Using Cluster Mode to Manage a Network of Switches
This section describes how to use clustering to create and manage Catalyst 4500 series switches using the standalone Network Assistant application or the command-line interface (CLI).
Beginning with Network Assistant 1.0 and 2.0, you can use clustering to group the switches in your network. You must enter the cluster run command on each switch to be managed. The major advantage is that you can manage 16 Catalyst 4500 series switches with one IP address.
Note Clustering is the auto- discovering mechanism used in CNA 1.0.
Note For complete procedures for using Network Assistant to configure switch clusters and communities, refer to Getting Started with Cisco Network Assistant, available at: http://www.cisco.com/univercd/cc/td/doc/product/rtrmgmt/cna/v2_0/gsg/index.htmCisco.com.
For the CLI cluster commands, refer to the Catalyst 4500 Series Switch Cisco IOS Command Reference and related publications at: http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122sr/cr/index.htm
This section contains the following topics:
•Understanding Switch Clusters
•Using the CLI to Manage Switch Clusters
Understanding Switch Clusters
These sections describe:
•Cluster Command Switch Characteristics
•Candidate Switch and Cluster Member Switch Characteristics
Note Clustering is disabled by default on the Catalyst 4500 series switch.
Clustering Overview
A switch cluster is a set of up to 16 connected, cluster-capable Catalyst switches that are managed as a single entity. The switches in the cluster use the switch clustering technology so that you can configure and troubleshoot a group of different Catalyst 4500 series switch platforms through a single IP address.
Using switch clusters simplifies the management of multiple switches, regardless of their physical location and platform families.
Note By default, Network Assistant in clustering mode discovers up to 7 hops away.
In a switch cluster, one switch must be the cluster commander switch, and up to 15 other switches can be cluster member switches. The total number of switches in a cluster cannot exceed 16 switches. The cluster command switch is the single point of access used to configure, manage, and monitor the cluster member switches. Cluster members can belong to only one cluster at a time.
Note Always chose a Catalyst 4500 series switch as the cluster command switch.
Cluster Command Switch Characteristics
A cluster command switch must meet these requirements:
•It is using Cisco IOS Release 12.2(20)EWA or later.
•It has an IP address.
•It has Cisco Discovery Protocol (CDP) version 2 enabled (the default).
•It is using cluster-capable software and has clustering enabled.
•It has IP HTTP server enabled.
•It has 16 VTY lines.
•It is not a command or cluster member switch of another cluster.
Note If your switch cluster contains a Catalyst 4500 series switch, the cluster command switch must also be a Catalyst 4500 series switch.
Network Assistant and VTY
Network Assistant uses virtual terminal (VTY) lines to communicate with the cluster command device. Catalyst 4500 series switches have 5 VTY lines configured by default. Network Assistant can employ an additional 8 lines. Therefore, you should configure the maximum number of lines (or at least, 8 + 5 = 13) so that Network Assistant can communicate with the switch and not use VTY lines that might be needed for telnet.
You can configure the Catalyst 4500 series switch to support an appropriate number of VTY lines with the line vty configuration command. For example, the line vty 6 15 command configures the switch to include 9 VTY lines.
Note If your existing VTY lines have non-default configurations, you might want to apply those configurations to the new VTY lines.
Candidate Switch and Cluster Member Switch Characteristics
Candidate switches are cluster-capable switches that have not yet been added to a cluster. Cluster member switches are switches that have been added to a switch cluster. Although not required, a candidate or cluster member switch can have its own IP address and password.
Note The host name of a candidate should not be in the form [a-zA-Z0-9]-n, where n is 0-16. These names are reserved.
To join a cluster, a candidate switch must meet these requirements:
•It is running cluster-capable software and has clustering enabled.
•It has CDP version 2 enabled.
•It has HTTP server enabled.
•It has 16 VTY lines.
•It is not a command or cluster member switch of another cluster.
•It is connected to the cluster command switch through at least one common VLAN.
Catalyst 4500 candidate and cluster member switches must be configured with an SVI on the VLAN connection to the cluster command switch.
Using the CLI to Manage Switch Clusters
You can configure cluster member switches from the CLI by first logging in to the cluster command switch. Enter the rcommand user EXEC command and the cluster member switch number to start a Telnet session (through a console or Telnet connection) and to access the cluster member switch CLI. The command mode changes and the Cisco IOS commands operate as usual. Enter the exit privileged EXEC command on the cluster member switch to return to the command-switch CLI.
This example shows how to log in to member-switch 3 from the command-switch CLI:
switch# rcommand 3
If you do not know the member-switch number, enter the show cluster members privileged EXEC command on the cluster command switch. For more information about the rcommand command and all other cluster commands, refer to the Catalyst 4500 Series Switch Cisco IOS Command Reference.
The Telnet session accesses the member-switch CLI at the same privilege level as on the cluster command switch. The Cisco IOS commands then operate as usual. For instructions on configuring the switch for a Telnet session, see the "Accessing the CLI Through Telnet" section on page 2-2.
Note CISCO-CLUSTER_MIB is not supported.
Configuring Network Assistant in Community or Cluster Mode
This section provides a detailed explanation of the CLI used to configure Network Assistant to work in a community or cluster. Network Assistant communicates with a Catalyst 4500 series switch by sending Cisco IOS commands over an HTTP connection.
The following topics are discussed:
•Configuring Network Assistant in Community Mode
•Configuring Network Assistant in Cluster Mode

Configuring Embedded CiscoView Support
The Catalyst 4500 series switch supports CiscoView web-based administration through the Catalyst Web Interface (CWI) tool. CiscoView is a device management application that can be embedded on the switch flash and provides dynamic status, monitoring, and configuration information for your switch. CiscoView displays a physical view of your switch chassis with color-coded modules and ports and monitoring capabilities that display the switch status, performance, and other statistics. Configuration capabilities allow comprehensive changes to devices, if the required security privileges have been granted. The configuration and monitoring capabilities for the Catalyst 4500 series of switches mirror those available in CiscoView in all server-based CiscoWorks solutions, including CiscoWorks LAN Management Solution (LMS) and CiscoWorks Routed WAN Management Solution (RWAN).
These sections describe the Embedded CiscoView support available with Cisco IOS Release 12.1(20)EW and later releases:
•Understanding Embedded CiscoView
•Installing and Configuring Embedded CiscoView
•Displaying Embedded CiscoView Information
Understanding Embedded CiscoView
The Embedded CiscoView network management system is a web-based interface that uses HTTP and SNMP to provide a graphical representation of the switch and to provide a GUI-based management and configuration interface. You can download the Java Archive (JAR) files for Embedded CiscoView at this URL at http://www.cisco.com/cgi-bin/tablebuild.pl/cview-cat4000
Installing and Configuring Embedded CiscoView
To install and configure Embedded CiscoView, perform this task:
|
|
|
---|---|---|
Step 1 |
Router# dir device_name |
Displays the contents of the device. If you are installing Embedded CiscoView for the first time, or if the CiscoView directory is empty, skip to Step 5. |
Step 2 |
Switch# delete device_name:cv/* |
Removes existing files from the CiscoView directory. |
Step 3 |
Switch# squeeze device_name: |
Recovers the space in the file system. |
Step 4 |
Switch# copy tftp bootflash |
Copies the tar file to bootflash. |
Step 5 |
Switch# archive tar /xtract tftp:// ip address of tftp server/ciscoview.tar device_name:cv |
Extracts the CiscoView files from the tar file on the TFTP server to the CiscoView directory. |
Step 6 |
Switch# dir device_name: |
Displays the contents of the device. In a redundant configuration, repeat Step 1 through Step 6 for the file system on the redundant supervisor engine. |
Step 7 |
Switch# configure terminal |
Enters global configuration mode. |
Step 8 |
Switch(config)# ip http server |
Enables the HTTP web server. |
Step 9 |
Switch(config)# snmp-server community string ro |
Configures the SNMP password for read-only operation. |
Step 10 |
Switch(config)# snmp-server community string rw |
