BootP automatic IP configuration/MAC address

The Ethernet Routing Switch 2500 Series has a unique 48-bit hardware address, or MAC address, that is printed on a label on the back panel. You can use this MAC address when you configure the network BootP server to recognize the Ethernet Routing Switch 2500 Series BootP requests. A properly configured BootP server lets the switch automatically learn its assigned IP address, subnet mask, IP address of the default router (default gateway), and software image file name.

For more information and an example of a BootP configuration file, see Appendix "Sample BootP configuration file" (page 351).

Choosing a BootP request mode

The BootP Request Mode field in the IP Configuration window lets you choose which method the switch uses to broadcast BootP requests:

•BootP or Default IP

•BootP Always

•BootP Disabled
