Using figure 8-7, above, switches 1 - 3 ignore these entries because the file implements IP Preserve and

their current IP addressing was not acquired through DHCP/Bootp.

Switch 4 ignores IP Preserve and implements the DHCP/Bootp addressing and IP Gateway specified in this file (because its last IP addressing was acquired from a DHCP/Bootp server).

Figure 8-8. Configuration File in TFTP Server, with DHCP/Bootp Specified as the IP Addressing Source

If you apply this configuration file to figure 8-7, switches 1 - 3 will still retain their manually assigned IP addressing. However, switch 4 will be configured with the IP addressing included in the file.
