"cannot access /sys/class/net//queues: No such file or directory" error in mq_mng.elg file

Product

Multi-Domain Security Management, VSX (Traditional)

Version

R80.40 (EOS), R81 (EOS), R81.10 (EOS), R81.20

Last Modified

Symptoms

After a reboot, the Multi-Queue configuration is incorrect when Management Data Plane Separation (MDPS), VSX, or both are enabled.

Notes:

Multi-Queue is set to auto.
CoreXL instances and interfaces are affined to the same CPU cores.
The mq_mng.elg file contains these errors:

[INFO] mq_driver.py:181:apply_state():  Apply state [1] queues num [20] cores
[0, 24, 1, 25, 2, 26, 3, 27, 4, 28, 5, 29, 6, 30, 7, 31, 8, 32, 9, 33] no_reset[False]

[ERROR] mq_mng:46:<module>(): Error [ls: cannot access /sys/class/net/<interface>/queues: No such file or directory

Example output of the mq_mng -o command:

eth2-01        i40e        Up       Dynamic (2/2)  18-35,54-71

Cause

The affinity settings do not apply to namespaces, and the namespaces do not appear in the /sys/class/net directory of the Virtual System (VS), Management Plane (mplane), and Data Plane (dplane).

As a result, Multi-Queue might affine CoreXL instances and interface queries to the same CPU cores.
