Using the BayStack 410-24T 10BASE-T Switch1-20 309985-B Rev 00BootP Automatic IP Configuration/MAC AddressThe BayStack 410-24T switch has a unique 48-bit hardware address, or MACaddress, that is printed on a label on the back panel. You use this MAC addresswhen you configure the network BootP server to recognize the BayStack 410-24Tswitch BootP requests.A properly configured BootP server enables the switch to automatically learn itsassigned IP address, subnet mask, IP address of the default router (defaultgateway), and software image file name.When the switch is participating in a stack configuration, a Stack MAC address isautomatically assigned during the stack initialization. The base unit’s MACaddress, with a software offset, is used for the Stack MAC address.For example, if the base unit’s MAC address is:00-00-82-99-44-00and the Stack software offset is:1Fthen the Stack MAC address becomes:00-00-82-99-44-1FIf another unit in the stack is assigned as the base unit, the MAC address of thenew base unit (with offset) now applies to the stack configuration. The originalstack IP address still applies to the new base unit.For an example of a BootP configuration file, see Appendix F, “Sample BootPConfiguration File.”
