Last Modified: Dec 18, 2024

Affected Product(s):
BIG-IP LTM(all modules)

Known Affected Versions:
15.1.0, 15.1.0.1, 15.1.0.2, 15.1.0.3, 15.1.0.4, 15.1.0.5, 15.1.1, 15.1.2, 15.1.2.1, 15.1.3, 15.1.3.1, 15.1.4, 15.1.4.1, 15.1.5, 15.1.5.1, 15.1.6, 15.1.6.1, 15.1.7, 15.1.8, 15.1.8.1, 15.1.8.2, 15.1.9, 15.1.9.1, 15.1.10, 15.1.10.2, 15.1.10.3, 15.1.10.4, 15.1.10.5, 15.1.10.6, 17.1.0, 17.1.0.1, 17.1.0.2, 17.1.0.3, 17.1.1, 17.1.1.1

Fixed In:
17.1.1.2

Opened: Feb 08, 2024

Severity: 3-Major

Symptoms

Excessive broadcast traffic can cause backplane F5CDP packets to be dropped by the FPGA metering. This issue affects the stability of the backplane and the overall health of the clustering system. When CDP packets are dropped, critical network topology and device information may not be communicated effectively, leading to potential disruptions and degraded performance in the cluster.

Impact

Chassis backplane and clustering issues.

Conditions

If Excessive broadcast traffic the backplane might become unstable.

Workaround

None

Fix Information

Upgrade BIG-IP with fix that includes F5CDP packet backplane fix.
