Last Modified: Dec 13, 2019

Bug Tracker

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

Fixed In:
15.1.0

Opened: Jul 11, 2019
Severity: 3-Major

Symptoms

TMM cannot redirect RRDAG traffic in vCMP guest. This can affect GTP traffic.

Impact

Traffic is pinned to tmm.0.

Conditions

Send UDP traffic to vCMP guest using RRDAG cmp-hash.

Workaround

None.

Fix Information

A new db variable has been added: dag.rrdag.redirect enable|disable The default value is disable. Enabling this db variable allows the BIG-IP system to evenly disaggregate UDP traffic that has low entropy in ports in hardware in vCMP mode. In vCMP guests, the BIG-IP system can redirect UDP traffic using non-default cmp hash.
