Edge Transport Node status is degraded if any interface is Down

Products

• VMware NSX
• VMware NSX-T Data Center

Issue/Introduction

• An Edge Transport Node status is degraded but data plane is functioning normally
• The Edge degraded state also triggers the corresponding Transport Zone status to be degraded
• The Edge has one or more network interfaces in a Down state

Environment

VMware NSX-T Data Center
VMware NSX

Cause

The Management Plane declares an Edge to be in a degraded state if any interface is Down regardless of whether that interface is used/configured.
If the Edge is a VM, the vNIC may be disconnected in vCenter. In the case of a baremetal Edge the NIC port may not be connected or have a link state down.
If the interface that is Down is not used, then there is no functional impact to the Edge.

Resolution

To avoid a degraded state ensure all Edge interfaces are connected and Up regardless of whether they are in use or not.
