Enabling Ip Preserve - HP ProCurve 6400cl Series Management And Configuration Manual

Figure 8-6. Example of Implementing IP Preserve in a Configuration File
IP Preserve: Retaining VLAN-1 IP Addressing Across Configuration File Downloads
If the switch's current IP addressing for VLAN 1 is from a DHCP server,
■
IP Preserve is suspended. In this case, whatever IP addressing the config­
uration file specifies is implemented when the switch downloads the file
and reboots. If the file includes DHCP/Bootp as the IP addressing source
for VLAN 1, the switch will configure itself accordingly and use DHCP/
Bootp. If instead, the file includes a dedicated IP address and subnet mask
for VLAN 1 and a specific gateway IP address, then the switch will
implement these settings in the startup-config file.
The ip preserve statement does not appear in show config listings. To verify
■
IP Preserve in a configuration file, open the file in a text editor and view
the last line. For an example of implementing IP Preserve in a configura­
tion file, see figure 8-6, below.

Enabling IP Preserve

To set up IP Preserve, enter the ip preserve statement at the end of a configu­
ration file. (Note that you do not execute IP Preserve by entering a command
from the CLI).
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.
