Article ID: KB36932 KB Last Updated: 31 May 2021Version: 1.0
Summary:

This article explains the meaning of the syslog message "if_pfe: Error 1 (Unknown) on IF command 55 (Ether set boolean)" that is usually seen on QFX5100 and QFX5200 Series devices. No action is required because these error messages do not have any service impact.


 
Symptoms:

The following logs are seen on QFX5100 and QFX5200 devices after events such as a reboot, interface flaps, or FPC reboot.

Dec 31 00:34:53  sw1 /kernel: %KERN-2: if_pfe: Error 1 (Unknown) on IF command 55 (Ether set boolean)

Dec 31 00:34:53  sw1 /kernel: %KERN-2: if_pfe: Error 1 (Unknown) on IF command 55 (Ether set boolean)
Cause:

These logs originate from the Packet Forwarding Engine (PFE) and the underlying chipset. They are reported when the device is unable to read certain PHY parameters from the drivers associated with the optics during initialization. They are seen after an interface gets re-initialized. 

This issue is mostly seen when non-Juniper SFPs are in use on these ports.

Solution:

No action is required because these logs do not have any service impact. The messages can be ignored safely. However, if any impact is seen or the error messages persist, contact Support to investigate the problem further.
