Last Modified: May 29, 2024

Affected Product(s):

Opened: Oct 06, 2021

Severity: 3-Major


When certain system failures occur and the dataplane cannot continue to handle network traffic, the BIG-IP system will automatically reboot. This behavior may restore traffic management, but it may prevent diagnosis of the failure.


Diagnosis of the dataplane failure is hindered.


Low-level system failure, possibly in HSB SRAM or other hardware



Fix Information

A new "sys db" variable "tmm.hsb.dataplanerebootaction" is added. The default value is "enable", which retains the previous behavior of rebooting, if a failure occurs making the dataplane inoperable. The value may optionally be set to "disable", which avoids an immediate system reboot by making the HA action be "go-offline-downlinks".

Behavior Change
