NSX Edge Node TEP Tunnel Remains Down During Failover or Upgrade in NSX 3.2.2.x

Products

• VMware NSX

Issue/Introduction

• While performing an upgrade of an NSX Edge cluster from 3.2.2.x to 4.2.2.2, or when forcing an Edge node failover, the Edge node tunnel between TEPs goes down.

• The tunnel remains down and fails to recover automatically.

• The tunnel state can be observed as down after powering off the active Edge node and powering it back on.

• The connection is only restored when one of the affected Edge node VMs is migrated via vMotion.

Resolution

Two Options:
