HA Configuration on PA-3220 - HA1 is UP but HA1 Backup is Down

L1 Bithead


I have both PA-3220 HA1-A and HA1-B links connected back to back to each other with a previously verified cable but only HA1 is coming up greeen while HA1 Backup is showing down. The HA1-B interface LEDs on both PA-3220 show green.


Any feedback or suggestion is greatly appreciated.

What release are you on? In 8.1.4 there's a bug involving the HA1-B does not come up as expected. Fixed in 8.1.4-h2 and later.


From the release note on 8.1.4-h2:


Fixed an issue on a PA-3200 Series firewall running PAN-OS 8.1.4 in an HA configuration where the HA1-B (backup) port did not come up as expected.

Same issue on PA-3260, PAN-OS 8.1.7... I'm asking to the customer support.

Same issue on PA-3220 with PAN-OS 8.1.8.

Looks like this issue came back in 9.1.6...

Same here, 3250 ha1 backup down, directly connected.

FYI - Here is a workaround for someone who wants to bring up the HA1 Backup before fixing it by upgrading the PAN-OS (if it's a bug - last time it was).

Step 1. Change the Port type from ha1-b to management on Active firewall and Commit (Device -> High Availability -> General > Control link (HA1 Backup)
Step 2. Revert back to the previous configuration with the Port type: ha1-b, along with the IP address and Commit.

This workaround should bring up the HA1 Backup.
Hope this helps!

Thanks for advice, i've noticed it before. It looks like PA is very devoted to management interface, even if there is no port chosen, management is used 🙂


Also this behaviour is observed after migration from older PA. As far as i see there is couple places where imported config has some artefacts comparing to manually made changes.



Issue is in 9.1.5 too, running 3220s also.


Had to swap port back and forth from ha1-b to mgmt as suggested


I assume PA are aware of it?

On the 3250 , 9.1.6 also passive PA reboot was required to made ha1-b back as active.

Same problem on a PA-3250 cluster just after upgrading to 9.1.5. Additional reboot needed just to bring the HA1-b Up again.

Same issue on a pair of 3320s. Rebooted the passive firewall, but no change, still red.



We are running PA 3260 in Active passive PAN OS 9.1.5 and 8.1.9.

No issues so far.

For me - it was also necessary to repeat these steps on the passive node

Try configuring gateway in ha port configuration, pointing one firewall to other.
