Configuring IP Addressing

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

Figure 8-6. Example of Implementing IP Preserve in a Switch Configuration File

For example, consider Figure 8-7:

Figure 8-7. Example of IP Preserve Operation with Multiple Switches Using the Same OS Software

If you apply the following configuration file to figure 8-7, switches 1 - 3 will

retain their manually assigned IP addressing and switch 4 will be configured

to acquire its IP addressing from a DHCP server.

Entering "ip preserve" in the last line of a configuration

file implements IP Preserve when the file is

downloaded to the switch and the switch reboots.

Switches 1 through 3 copy and implement the config.txt file

from the TFTP server (figure 8-8), but retain their current IP

config.txt file from the TFTP server (figure 8-8),

but acquires new IP addressing from the DHCP
