DHCP Client Configuration
No configuration file is present on Switch 1 through Switch 4.
Configuration Explanation
In Figure 6-3, Switch 1 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 1
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 host name
(switch1).
• It reads the configuration file that corresponds to its host name; for example,
it reads switch1-confg from the TFTP server.
Switches 2 through 4 retrieve their configuration files and IP addresses in the
same way.
