DNS Server Configuration
The DNS server maps the TFTP server name tftpserver to IP address 10.0.0.3.
TFTP Server Configuration (on UNIX)
The TFTP server base directory is set to /tftpserver/work/. This directory contains the network-confg file
used in the two-file read method. This file contains the hostname to be assigned to the switch based on
its IP address. The base directory also contains a configuration file for each switch (switcha-confg,
switchb-confg, and so forth) as shown in this display:

DHCP Client Configuration
No configuration file is present on Switch A through Switch D.
Configuration Explanation
In
, 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.
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.
