Starting from R80.20, Sticky Decision Function (SDF) was completely removed. Connection stickiness is achieved via other methods that don’t require disabling SecureXL.
In pre-R80.20, SecureXL and Sticky Decision Function in ClusterXL Load Sharing mode are not supported together.
The following two options are available:
- Either disable SecureXL on each cluster member,
- Or disable Sticky Decision Function in ClusterXL object in SmartDashboard and install policy.
Note: When disabling or re-enabling Sticky Decision Function (SDF) you must install policy twice otherwise you SecureXL status will display "Waiting for Policy"
This limitation is described in every ClusterXL Administration Guide (R77.X, R80.10) - Chapter 'Sticky Connections'.
