Configure NetFlow Exports

Create a NetFlow server profile.
The profile defines which NetFlow collectors will receive the exported records and specifies export parameters.
Select
Device
Server Profiles
NetFlow
and
Add
a profile.
Enter a
Name
to identify the profile.
Specify the rate at which the firewall refreshes NetFlow Templates in
Minutes
(default is 30) and
Packets
(exported records—default is 20), according to the requirements of your NetFlow collector. The firewall refreshes the templates after either threshold is passed.
Specify the
Active Timeout
, which is the frequency in minutes at which the firewall exports records (default is 5).
Select
PAN-OS Field Types
if you want the firewall to export App-ID and User-ID fields.
Add
each NetFlow collector (up to two per profile) that will receive records. For each collector, specify the following:
Name
to identify the collector.
NetFlow Server
hostname or IP address.
Access
Port
(default 2055).
Click
OK
to save the profile.
Assign the NetFlow server profile to the firewall interfaces where traffic you want to analyze is ingressing.
In this example, you assign the profile to an existing Ethernet interface.
Select
Network
Interfaces
Ethernet
and click an interface name to edit it.
You can export NetFlow records for Layer 3, Layer 2, virtual wire, tap, VLAN, loopback, and tunnel interfaces. For aggregate Ethernet interfaces, you can export records for the individual sub-interfaces that data flows through within the group.
Select the NetFlow server profile (
NetFlow Profile
) you configured and click
OK
.
(
Required for PA-7000 Series, PA-5400 Series, and PA-5200 Series firewalls
)
Configure a service route for the interface that the firewall will use to send NetFlow records.
You cannot use the management (MGT) interface to send NetFlow records from the PA-7000 Series, PA-5400 Series, and PA-5200 Series firewalls. For other firewall models, a service route is optional. For all firewalls, the interface that sends NetFlow records does not have to be the same as the interface for which the firewall collects the records.

(
Firewall with multiple virtual systems
)
Select one of the following:
Global
—Select this option if the service route applies to all virtual systems on the firewall.
Virtual Systems
—Select this option if the service route applies to a specific virtual system. Set the
Location
to the virtual system.
Select
Service Route Configuration
and Customize.
Select the protocol (
IPv4
or
IPv6
) that the interface uses. You can configure the service route for both protocols if necessary.
Click
Netflow
in the Service column.
Select the

.
Any

MGT
are not valid interface options for sending NetFlow records from PA-7000 Series, PA-5400 Series, or PA-5200 Series firewalls.
Select a

Monitor the firewall traffic in a NetFlow collector.
Refer to your NetFlow collector documentation.
When monitoring statistics, you must match the interface indexes in the NetFlow collector with interface names in the firewall web interface. For details, see Firewall Interface Identifiers in SNMP Managers and NetFlow Collectors.
To troubleshoot NetFlow delivery issues, use the operational CLI command
debug log-receiver netflow statistics
