Last Modified: Jun 30, 2021

Bug Tracker

Affected Product:  See more info
BIG-IP TMOS(all modules)

Known Affected Versions:
14.1.0, 14.1.0.1, 14.1.0.2, 14.1.0.3, 14.1.0.5, 14.1.0.6, 14.1.2

Fixed In:
15.0.0, 14.1.2.1

Opened: Mar 29, 2019
Severity: 3-Major

Symptoms

The packet samples transmitted from BIG-IP to an sFlow receiver may contain only 'http' samples, with no 'vlan' or 'interface' FLOW samples appearing. sFlow will continue to transmit CNTR (counter) telemetry packets.

Impact

External network-monitoring or management systems, which may depend on sFlow packet samples from BIG-IP systems and from other equipment, are unable properly to characterize the flow of data throughout the network.

Conditions

When the BIG-IP system is configured with one or more sFlow receivers, with non-zero sampling-rate configured for 'vlan' or 'interface' types.

Workaround

None.

Fix Information

This issue no longer occurs.
