Restore the Firewall Configuration after Replacement
Perform initial configuration
on the new firewall and verify network connectivity.
|
Use a serial port connection or a Secure Shell (SSH) connection to add an IP address, a DNS server IP address, and to verify that the new firewall can access the Palo Alto Networks updates server.
|
(
Optional
) Set the Operational mode on the new firewall to match that on the old firewall.
A serial port connection is required for this task.
|
Enter the following CLI command to access maintenance mode on the firewall:
> debug system maintenance-mode
For Operational mode, select
Set FIPS Mode
or
Set CCEAL 4 Mode
from the main menu.
|
Retrieve the license(s) on the new firewall.
|
Enter the following command to retrieve the licenses:
> request license fetch
|
(
Optional
) Match the operational state of the new firewall with that of the old firewall. For example, enable multi-virtual system (multi-vsys) capability for a firewall that was enabled for multi-vsys capability.
|
Enter the commands that pertain to your firewall settings:
> set system setting multi-vsys on
> set system setting jumbo-frame on
|
Upgrade the PAN-OS version on the new firewall.
You must upgrade to the same PAN-OS installed on the old firewall. You must upgrade the content release versions to the same or later version that is installed on the old firewall.
|
Enter the following commands:
To upgrade the content release version:
> request content upgrade download latest
> request content upgrade install version latest
To upgrade the PAN-OS software version:
> request system software download version <
version
>
> request system software install version <
version
>
|
Go to the Panorama CLI and export the device state bundle from the old firewall to a computer using Secure Copy (SCP) or TFTP (you cannot do this from the web interface).
If you manually exported the device state from the firewall, you can skip this step.
The export command generates the device state bundle as a tar zipped file and exports it to the specified location. This device state will not include the LSVPN dynamic configuration (satellite information and certificate details).
|
Enter one of the following commands:
> scp export device-state device <
old serial#
> to <
login
> @ <serverIP>: <path>
or
> tftp export device-state device <
old serial#
> to <
login
> @ <
serverIP
>: <
path
>
|
Replace the serial number of the old firewall with that of the new replacement firewall on Panorama.
By replacing the serial number on Panorama you allow the new firewall to connect to Panorama after you restore the configuration on the firewall.
|
Enter the following command in Operational mode:
>
replace device old
<
old SN#
>
new
<
new SN#
>
Enter Configuration mode and commit your changes.
>
configure
# commit
Exit Configuration mode.
# exit
|
On the new firewall, import the device state and commit the changes.
|
Access the web interface of the new firewall.
Select
Device > Setup > Operations
and click the
Import Device State
link in the Configuration Management section.
Browse to locate the file and click
OK.
Click
Commit
to save you changes to the running configuration on the firewall.
|
From Panorama, verify that you successfully restored the firewall configuration.
|
Access the Panorama web interface and select
Panorama > Managed Devices.
Verify that the Connected column for the new firewall has a check mark.
|
Synchronize the firewall with Panorama.
|
From Panorama, click
Commit, set the
Commit Type
to
Device Group, select the device group that contains the firewall, select the
Include Device and Network Template
check box, and click
Commit
again.
(
M-Series only
) If your firewalls forward logs to Log Collectors, click
Commit, set the
Commit Type
to
Collector Group, select the Collector Group that contains the firewall, and click
Commit
again.
If you need to generate reports for a period when the old firewall was still functional after you installed the new firewall, you must generate a separate query for each firewall serial number because replacing the serial number on Panorama does not overwrite the information in logs.
