GET /api/v1/transport-nodes/<nodeID>/network/interfaces/vusb0/stats fails in NSX

Products

• VMware NSX

Issue/Introduction

• ESXi hosts are configured with a vusb interface in vCenter.
• NSX is in use with an external servicing polling the NSX Manager for interface statistics using:

  GET /api/v1/transport-nodes/<nodeID>/network/interfaces/vusb0/stats

• Entries similar to the below are observed in /var/log/syslog on the NSX Manager:

  NSX 77794 SYSTEM [nsx@6876 audit="true" comp="nsx-manager" level="INFO" subcomp="manager"] UserName:'<username>' ModuleName:'common-services' Operation:'GET@/api/v1/transport-nodes/########-####-####-####-############/network/interfaces/vusb0/stats' Operation status: 'failure' Error: The requested object : Provided interface id vusb0 in the request is invalid could not be found. Object identifiers are case sensitive.

• There is no impact associated with the behavior.
