Configuration | System | IP Routing | DHCP Options This section lets you configure DHCP options. Figure 7-6 Configuration | System | IP Routing | DHCP Options Screen DHCP Option DHCP Options are facilities that allow the VPN 3002 DHCP server to respond to configurable parameters for specific kinds of devices such as PCs, IP telephones, print servers, etc., as well as an IP address. Add/Modify/Delete To configure and add DHCP options, click Add. The Manager opens the Configuration | System | IP | DHCP Options | Add screen.To modify a configured DHCP option, select the option from the list and click Modify. The Manager opens the Configuration | System | IP | DHCP Options | Modify screen. VPN 3002 Hardware Client Reference OL-1893-01 7-7 Chapter 7 IP Routing Configuration | System | IP Routing | DHCP Options | Add or Modify To remove a configured DHCP option, select the option from the list and click Delete. There is no confirmation or undo. The Manager refreshes the screen and shows the remaining DHCP options in the list. Reminder: The Manager immediately includes your changes in the active configuration. To save the active configuration and make it the boot configuration, click the Save Needed icon at the top of the Manager window. Configuration | System | IP Routing | DHCP Options | Add or Modify These screens let you: Add a new DHCP option to the list of DHCP options this VPN 3002 uses. Modify a configured DHCP option. Figure 7-7 Configuration | System | IP Routing | DHCP Options | Add Screen DHCP Option Use the pull-down menu to the DHCP Options field to select the option you want to add or modify. You can add or modify only one option at a time. Option Value Enter the value you want this option to use, for example, the IP address for the TFTP server option, the number of seconds for the ARP Cache Timeout option, 1 or 0 to enable or disable IP forwarding, etc. 7-8 VPN 3002 Hardware Client Reference OL-1893-01 Chapter 7 IP Routing Configuration | System | IP Routing | DHCP Options | Add or Modify Nonconfigurable DHCP Options You cannot configure the following DHCP Options: • Subnet Mask (option 1) • Router (option 3) • Domain Name Server (option 6) • Domain Name (option 15) • NetBios Name Server/WINS (option 44). 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.
