DNS Server Configuration
The DNS server maps the TFTP server name maritsu 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 host name to be assigned to the switch based on
its IP address. The base directory also contains a configuration file for each switch (switch1-confg,
switch2-confg, and so forth) as shown in this example:
prompt> cd /tftpserver/work/
prompt> ls
network-confg
switch1-confg
switch2-confg
switch3-confg
switch4-confg
prompt> cat network-confg
ip host switch1 10.0.0.21
ip host switch2 10.0.0.22
ip host switch3 10.0.0.23
ip host switch4 10.0.0.24
DHCP Client Configuration
No configuration file is present on Switch 1 through Switch 4.

4-3, 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.
