Bug ID 650152: Support AES-GCM acceleration in Nitrox PX wlite VCMP platforms

Last Modified: Sep 13, 2023

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

Known Affected Versions:
12.1.0, 12.1.1, 12.1.2, 13.0.0, 13.0.0 HF1, 13.0.0 HF2, 13.0.0 HF3, 13.0.1

Fixed In:
13.1.0, 12.1.3

Opened: Mar 09, 2017

Severity: 3-Major


In Nitrox PX platforms, vCMP guests can't accelerate AES-GCM traffic, which might cause high CPU usage.


High CPU usage.


For those vCMP guests deployed on Nitrox PX-based platforms, and SSL cipher is configured to use AES-GCM. The following blades support the Nitrox PX and vCMP combination: VIPRION B4200, B4300, B2100, and B2150 blades.


No workaround.

Fix Information

Added AES-GCM hardware acceleration support for Nitrox PX-based vCMP.
