7.3.1 Network Boot Process
The network boot process is as follows:
1. The switch sends a BOOTP request over the network.
Figure 7.1 -
BOOTP Request
The boot request contains the switch’s MAC address. The boot server contains a
bootptab file with an entry for the switch which is defined by the MAC address.
2. If a boot server which holds the software for the switch receives the boot request,
it loads the boot software over the network to the destination MAC address.
