Bug ID 1008585: L2 Table corruption results in a traffic loss.

Last Modified: May 29, 2024

Affected Product(s):
F5OS Velos(all modules)

Known Affected Versions:
F5OS-C 1.1.0

Fixed In:
F5OS-C 1.1.2, F5OS-C 1.1.1, F5OS-A 1.0.0

Opened: Apr 02, 2021

Severity: 2-Critical

Symptoms

The Layer 2 (L2) table on a blade can become corrupted under certain conditions. When this happens, traffic to the affected destination (either a tenant or a external interface) do not flow properly.

Impact

Traffic loss to a tenant or the front-panel interfaces. This may include partial or full packet loss to the tenant.

Conditions

-- VELOS system with more than one blade installed. -- A packet for a tenant associated with one blade arrives on a different blade that is encountering the L2 table corruption.

Workaround

None

Fix Information

FPGA Manager now detects the corruption so incorrect entries are not written to the L2 table. This prevents traffic loss from occurring.
