Catalyst 6500 Series, 4500 Series, and 5000 Family Switches Web Interface Installation and Configuration Note

This installation and configuration note describes how to configure the Hypertext Transfer Protocol (HTTP) server and authentication login for the Catalyst Web Interface (CWI). It also describes how to download the Catalyst version of CiscoView (Catalyst CV) to your client.

Note For the Catalyst 6500 series switches, the CWI is bundled with an online software image on Cisco.com. If your software image includes CWI, the name of the image contains "cv" appended to the supervisor engine. For example, an image for the Catalyst 6500 series switch is cat6000-sup2cvk8.8-1-3.bin.

Note For the Catalyst 4500 series switches, the CWI is not bundled with an online software image on Cisco.com. You can download the CWI as a totally separate image from the supervisor engine software at the following URL: http://www.cisco.com/cgi-bin/tablebuild.pl/cat4000.

Note For the Catalyst 5000 family switches, the CWI image is 8 MB. You must download the image to the PCMCIA card because it will not fit in the bootflash. You must also manually synchronize the CWI image to the standby supervisor engine.

Understanding How the CWI Works

The CWI is a browser-based tool that you can use to configure the Catalyst 6500 series, Catalyst 4500 series, Catalyst 4000 series, Catalyst 5000 family, Catalyst 2948G, Catalyst 2948G-GE-TX, Catalyst 2980G, Catalyst 2980G-A, and Catalyst 4912G vmswitches. It consists of a graphical user interface (GUI) that runs on the client (Catalyst CV) and an HTTP server that runs on the switch.

The CWI provides a real-time graphical representation of the switch and detailed information, such as port status, module status, type of chassis, and modules.

Following a successful download, the Catalyst CV opens and displays switch information in your browser. The CWI obtains this information from the switch using SNMP requests.

Note The CWI uses HTTP to download the Catalyst CV from the server to the client. HTTP is the TCP/IP protocol that the World Wide Web uses to exchange HTML documents.

Communication between the client and server usually occurs on a TCP/IP connection. The TCP/IP port number for HTTP is 80. In this client-server mode, the client opens a connection to the server and sends a request. The server receives the request, sends a response back to the client, and closes the connection.

The HTTP server supports the following requests:

•HTTP 0.9 (simple requests)

•HTTP 1.0 (full requests)

•HTTP 1.1 (full requests)

The HTTP server responds to a simple request with a simple response and to a full request with a full response.

In the default state, the HTTP server is disabled. To enable the CWI, you must enable the HTTP server. After you enable the HTTP server, it listens for requests on port number 80. You can change the TCP/IP port number to any port number from 1 to 65,535 at the CLI. If you change the TCP/IP port number that is not 80, then you will need to append the port number to the IP address of the switch. For example, if the IP address of the switch is http://10/77/209.183, and you change the TCP/IP port number to 900, then the URL for the switch will be http://10.77.209.183:900.

Although the system uses HTTP 1.0, it also supports HTTP 1.1 messaging.

Configuring the CWI

Before you can access the Catalyst CV, you need to perform the tasks in these sections:

• Configuring the HTTP Server

• Configuring Authentication Login

Configuring the HTTP Server

To configure the HTTP server, perform this task at the CLI:

 
Task
Command

Step 1 

Assign an IP address to the switch, if necessary.

set interface sc0 [ip_addr / netmask]

Step 2 

Enable the HTTP server on the switch.

set ip http server enable

Step 3 

Configure the HTTP port

Note The TCP/IP port default is 80; perform this step only if you need to change the default.

set ip http port port_number default

Step 4 

Verify the HTTP server and CWI support.

show ip http

Step 5 

Display the CWI version.

show version

Step 6 

Display the CWI configuration.

show config

Note The show ip http command displays the CWI status. If the switch supports the CWI, the "Web Interface" status field shows "Supported." If the switch does not support the CWI, the field shows "Not Supported."

Configuring Authentication Login

The Catalyst switch software allows you to authenticate console and Telnet logins using the RADIUS/TACACS/Kerberos/Local database. With software release 5.4(2) or later releases, you can also authenticate HTTP users.

When you log into the switch using HTTP, a dialog box appears and prompts you for your username and password. After you provide your username and password, the system authenticates your login with the HTTP user-authentication method. The system denies access unless the username and password are valid.

In the default configuration, verification is enabled for all users of the CWI. The system validates the login password against the local login password.

Authentication for the CWI occurs at these two security levels:

•Level 1—Username and Password Authentication

Level 1 requires you to obtain authentication by providing a username and password. This process is similar to the authentication that you obtain at the command prompt for Telnet and console sessions.

After you pass the first level of security, you can download the Catalyst CV.

•Level 2—SNMP IP Permit Restriction

Level 2 restricts the IP address of the incoming SNMP request. You must configure the IP address of the SNMP request correctly before the CWI can communicate with the switch.

Note CWI does not support SNMP v3.

To configure authentication, perform this task at the CLI:

 
Task
Command

Step 1 

Configure authentication login.

set authentication login enable [console | telnet | http | all] [primary]

Step 2 

Display authentication.

show authentication

This example shows how to configure the authentication login for the HTTP option:

Console> (enable) set authentication login tacacs enable http primary
Tacacs authentication set to enable for HTTP sessions as primary authentication method.
Console> (enable) set authentication login radius disable http primary
Tacacs authentication set to disable for HTTP sessions.

For detailed information on configuring the authentication login, refer to the "Configuring Switch Access Using AAA" chapter of the Software Configuration Guide for your switch.

Downloading the Catalyst CV to the Client

To download the Catalyst CV from your browser, follow these steps:

Step 1 Enter the switch address in the URL field of your browser. For example, open Netscape Navigator or Internet Explorer and enter the following:

http://172.20.14.89

In this example, 172.20.14.89 is the switch IP address.

After you connect to the switch, a login dialog appears and prompts for your username and password.

Step 2 Provide your username and password.

The home page of the switch appears on your browser.

Step 3 Click Switch Manager to download the Catalyst CV.

The switch downloads the Catalyst CV, and your browser opens with a real-time view of the switch chassis.

Note The CWI communicates with the switch through SNMP requests. If you enable the IP permit feature, you must set the IP address of the browser to "permitted" in the IP permit list for SNMP. For detailed information on configuring IP permit lists, refer to the "Configuring IP Permit List" chapter of the Software Configuration Guide for your switch.

Using the Catalyst CV

The Catalyst CV is a subset of the CiscoView Network Management System. Most of the monitoring features that are available in CiscoView are not available in the Catalyst CV. For example, you cannot monitor CPU, porrt counters, or memory usage in the Catalyst CV. However, the Catalyst CV does provide a clear view of which ports are up and running and which ports are down.

Note The non-embedded CiscoView (client/server CiscoView) can be launched form a device loaded with the CV image.

The primary purpose of the Catalyst CV is to provide a GUI to configure the switch for those customers who do not want to purchase the CiscoView Network Management System. For information on how to configure a Catalyst switch with the Catalyst CV, refer to the "Configuring Devices" chapter in the CiscoView documentation.

For documentation on how to use the Non-Embedded CiscoView, refer to the following URL: http://www.cisco.com/en/US/partner/products/sw/cscowork/ps4565/index.html.
