Persistence tables is empty on Edge CLI when cookie persistence is configured on NSX LB

Products

• VMware NSX

Issue/Introduction

• Enabled cookie based persistence using the default custom persistence profile
• You can see the traffic in LB session table but the output of command 'get load-balancer <LB-UUID> persistence-tables' will show empty result

         

 

Environment

VMware NSX 4.x

VMWare NSX-T Datacenter 3.x

Cause

 The load balancer does not maintain any persistence table for cookie persistence. Instead, it encodes the necessary information in the HTTP cookie value sent to client and relies on the client to store it and send it back in subsequent related HTTP requests.

Resolution

This behavior is by design.
