HA2 link down

[BigPalo]

The 20G link for HA2 between the two PA-5220 firewalls (Active-Passive cluster) does not work correctly. It is a direct link using single-mode fiber and 10G-LR optics with a length of approximately 550 meters.

After restarting any of the two firewalls, the HA2 link does not raise (in the Down state). We only managed to lift it after disconnecting and reconnecting the fiber patch on either of the two firewalls.

On other occasions, the HSCI port enters a flaping loop (UP / Down) continuously. It is solved by disconnecting the fiber.

We have certified the single mode link with 20G-LR working fine(included patch cords).

The firmware version of the fws is 8.0.12.

Its seems like a bug but i can not find any bug related to this in 8.0.12.

I just had a call with Palo yesterday, and I seem to recall hearing about a HSCI bug...might want to open a support case on your issue.

@BigPalo,

The HSCI interface has been causing a lot of issuess on the PA-3200 series as of late, but I haven't heard about many issues with the 5200 series. I'd do what @Brandon_Wertz recommends and open a ticket on the manner, it appears that HSCI is really finiky at the moment and might be better avoided if your setup allows for it.

We have PA 5220 in Active passive running Pan OS 8.1.9

We have HA2  connection on HSCI port with 40Gig QSFP ER

Every few hours link goes down and then comes back automatically

In other words it is flapping.

Fiber is single mode tested and also QSFP+ tested and certified.

Any ideas?

@MP18,

Are these physically separated by a distance that justifies SM or are these sitting in close proximity?
