Bug ID 427239: Default node monitor causes nodes to be left unchecked after sync

Last Modified: Jul 12, 2023

Affected Product(s):
BIG-IP None(all modules)

Known Affected Versions:
11.4.0, 11.4.1

Fixed In:
11.5.0, 11.4.1 HF9, 11.4.0 HF4

Opened: Aug 06, 2013

Severity: 2-Critical


When multiple devices are in a failover device group and a default node monitor is being used, removing the default node monitor, synchronizing the configuration, then recreating it and re-synchronizing will cause other devices' nodes to move to the unchecked state.


Affected nodes will be left in the unchecked state.


This only affects configurations that have a default node monitor configured.


Temporarily turn on full-load-only sync on the failover device group, or use the 'Overwrite Configuration' option in the device group sync page of the GUI.

Fix Information

The default node monitor now syncs even when full-load-on-sync is false on the failover device group.
