Bug ID 1850165: Missing internal interface pgindex field causes l2-agent to restart

Last Modified: Jul 12, 2025

Affected Product(s):
F5OS Install/Upgrade, Velos(all modules)

Fixed In:
F5OS-C 1.8.1

Opened: Mar 11, 2025

Severity: 3-Major

Symptoms

Upon upgrade from 1.1 -> 1.6 -> 1.8, l2-agent on blade will exit due to interface data mismatch. This mismatch happens because the pgindex hidden leaf is missing from cdb, but the l2-agent on blade expects it.

Impact

Dataplane is not functioning.

Conditions

Chain upgraded from 1.1 -> 1.6 -> 1.8. Version 1.8 is the version where l2-agent added more logic to check interface data inconsistency.

Workaround

Work around is to delete the blades from the partition and re-add them. This will require user to reconfigure interface data (vlans, lag members).

Fix Information

With this fix, the upgrade into 1.8 will work as expected, and l2-agent on the blade will find matching interface data.
