The Catalyst Web Interface (CWI) is a browser-based tool that you can use to configure the Cisco 6000, 5000, and 4000 Family Switches. It consists of a graphical user interface (GUI) that runs on the client, Catalyst CiscoView (CV), and a Hypertext Transfer Protocol (HTTP) server that runs on the switch. A GUI alternative to the CLI and SNMP interfaces, 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. The CWI uses HTTP to download Catalyst CV from the server to the client. 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. To configure the HTTP server on a set
command-based switch, perform the following tasks at the CLI:
Catalyst Switch software allows you to configure authentication for console and Telnet logins using the RADIUS/TACACS/Kerberos/Local database. With software Release 5.4(2) or later, you can also configure authentication for 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:
To configure authentication, perform these tasks at the CLI:
The example in Figure To download the Catalyst CV from your browser, follow these steps: Step 1 - Enter the switch address in the Universal Resource Locator (URL) field of your browser. For example, open Netscape Navigator or Internet Explorer and enter the following:
Step 2 - Provide your username and password. The home page of the switch appears on your browser. Step 3 - Click the Switch Manager link to download the Catalyst CV. The switch downloads the Catalyst CV, and your browser opens with a real-time view of the switch chassis.
