Retrieving IP Information Using DHCP-Based Autoconfiguration: Example
Switch A reads its configuration file as follows:
It obtains its IP address 10.0.0.21 from the DHCP server.
If no configuration filename is given in the DHCP server reply, Switch A reads the network-confg file from the base
directory of the TFTP server.
It adds the contents of the network-confg file to its host table.
It reads its host table by indexing its IP address 10.0.0.21 to its hostname (switcha).
It reads the configuration file that corresponds to its hostname; for example, it reads switch1-confg from the TFTP
server.
Switches B through D retrieve their configuration files and IP addresses in the same way.
Figure 4 on page 75 shows a sample network for retrieving IP information by using DHCP-based autoconfiguration.

Table 15 on page 75 shows the configuration of the reserved leases on the DHCP server.
