Configuring IP Addressing
IP Preserve: Retaining VLAN-1 IP Addressing Across Configuration File Downloads
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.

IP Preserve Command
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).

Because switch 4 (figure 8-7) received
its most recent IP addressing from a
DHCP/Bootp server, the switch
ignores the ip preserve command and
implements the IP addressing
included in this file.
