You configure these values on the central-site VPN Concentrator for the group to which the VPN 3002 Hardware Client belongs. As is the case for all group configuration parameters, the central-site VPN Concentrator pushes these values to the VPN 3002 over the tunnel.

This section explains how you configure and enable those servers. Configuration | System | Management Protocols This section of the Manager lets you configure and enable built-in VPN 3002 servers that provide management functions using: • HTTP/HTTPS: Hypertext Transfer Protocol, and HTTP over SSL (Secure Sockets Layer) protocol. • Telnet: terminal emulation protocol, and Telnet over SSL. • SNMP: Simple Network Management Protocol. • SNMP Community Strings: identifiers for valid SNMP clients. • SSL: Secure Sockets Layer protocol. • SSH: Secure Shell. • XML: EXtensible Markup Language Figure 8-1 Configuration | System | Management Protocols Screen VPN 3002 Hardware Client Reference OL-1893-01 81 Chapter 8 Management Protocols Configuration | System | Management Protocols | HTTP/HTTPS Configuration | System | Management Protocols | HTTP/HTTPS This screen lets you configure and enable the VPN 3002 HTTP/HTTPS server: Hypertext Transfer Protocol and HTTP over SSL (Secure Sockets Layer) protocol. When the server is enabled, you can use a Web browser to communicate with the VPN 3002. HTTPS lets you use a Web browser over a secure, encrypted connection. About HTTP/HTTPS The Manager requires the HTTP/HTTPS server. If you click Apply, even if you have made no changes on this screen, you break your HTTP/HTTPS connection and you must restart the Manager session from the login screen. If you disable either HTTP or HTTPS, and that is the protocol you are currently using, you can reconnect with the other protocol if it is enabled and configured. If you disable both HTTP and HTTPS, you cannot use a Web browser to connect to the VPN 3002. Use the Cisco command-line interface from the console or a Telnet session.
