Configuring DHCP/Bootp

In its default configuration, the hub is configured for DHCP/Bootp operation. However, if an IP address has previously been configured or if the IP Config parameter has been set to Disabled, then you will need to use this procedure to reconfigure the parameter to enable DHCP/Bootp operation. This procedure assumes that, for Bootp operation:

• A Bootp database record has already been entered into an appropriate Bootp server.
• The necessary network connections are in place.
• The Bootp server is accessible from the switch and, for DHCP operation:
• The necessary network connections are in place.
• A DHCP server is accessible from the switch.

To use the web browser interface to configure the hub for DHCP/Bootp:

1. Click on Configuration | IP Configuration.
2. Click on the IP Configuration pull-down menu and select Bootp/DHCP.
3. Click on Apply Changes.

To use the console interface to configure the hub for Bootp/DHCP operation, refer to the Management and Configuration manual you received with the hub (and also available in the Support area of HP's Proactive Net website).

When you either click on Apply Changes to save the configuration change or reboot the switch with DHCP/Bootp enabled in a network providing DHCP/Bootp service, the hub does the following: Receives an IP address and subnet mask and, if configured in the server, a gateway IP address. For Bootp operation, if the reply provides information for downloading a configuration file, the switch then uses TFTP to download the file from the designated source, then reboots itself. (This assumes that the hub has connectivity to the TFTP file server specified in the Bootp database configuration record and that the Bootp database record is correctly configured.)
