Easiest way to find and replace Interfaces

L2 Linker

What is an easy way to find and replace Palo Alto interfaces?

 

Let's say for example I am combining a bunch of interfaces such as ethernet1/9 and ethernet 1/10 into an aggregation group (i.e. ae1) and adding these as tagged VLANS i.e. ae1.123, ae1.456

 

Q: Is there an easy way to migrate over replacing the Interfaces for all the NAT rules, IKE Gateways, Static Routes, etc.?

I recently had to do something very similar and documented my procedure.  First I tried it in Expedition which is what the tool was designed for but it just wouldn't work for me.  I moved my subinterfaces from one ae to another this way:

## set panorama to display output in "set" commands, set panorama to "no-more" output
admin@firewall(primary-active)> set cli config-output-format set
admin@firewall(primary-active)> set cli pager off
admin@firewall(primary-active)> configure
Entering configuration mode
[edit]

## from panorama, show the configuration matching the interface being migrated
admin@firewall(primary-active)# show | match ae2.117

## the only configuration we need to remove have been marked with ** at the beginning of the line

## remove the sub-interfaces from the BGP peer-group by temporarily replacing them with loopbacks (this will preserve the bgp-peer config while allowing us to delete the sub-interface)
set template TEMPLATE config network virtual-router DEFAULT-VR protocol bgp peer-group ZONE peer FW1 local-address interface loopback.1
set template TEMPLATE config network virtual-router DEFAULT-VR protocol bgp peer-group ZONE peer FW2 local-address interface loopback.1

## delete the sub-interface from the VR
delete template TEMPLATE config network virtual-router DEFAULT-VR interface ae2.117

## delete the sub-interface from the zone
delete template TEMPLATE config vsys vsys1 zone ZONE network layer3 ae2.117

## delete the sub-interface from the vsys
delete template TEMPLATE config vsys vsys1 import network interface ae2.117

## delete the sub-interface from the old AE
delete template TEMPLATE config network interface aggregate-ethernet ae2 layer3 units ae2.117

## create the new sub-interface on new AE

## import the new interface to the correct vsys
set template TEMPLATE config vsys vsys1 import network interface ae3.117

## add the new interface to the zone
set template TEMPLATE config vsys vsys1 zone ZONE network layer3 ae3.117

## add the new interface to the VR
set template TEMPLATE config network virtual-router DEFAULT-VR interface ae3.117

## add the new subinterface to the BGP peer-group (replacing the loopback placeholder)

set template TEMPLATE config network virtual-router DEFAULT-VR protocol bgp peer-group ZONE peer FW2_ZONE local-address interface ae3.117
