Estimated reading time: 1 minute

The following ports must be open to access the full set of Workload Orchestrator features:

Acronym Full Name Port Description
HTTP Hypertext Transfer Protocol 80 This client-server protocol enables web data exchange between browsers and servers.
HTTPS Hypertext Transfer Protocol - Secure 443 The secure version of the HTTP protocol encrypts all requests and responses with Transport Layer Security (TLS) or Secure Socket Layer (SSL).
LWM2M Lightweight Machine-to-Machine 5683

This OMA (Open Mobile Alliance) Lightweight Machine-to-Machine (LWM2M) protocol provides device management via client-server application layer communication. HPE provides the LWM2M server. LWM2M-compatible devices, like OT Link Platform-enabled devices, are the clients.

LWM2M with DTLS Lightweight Machine-to-Machine - Secure 5684 The secure version of the LWM2M protocol uses Datagram Transport Layer Security (DTLS).
BS Bootstrap 15683 Bootstrap is related to LWM2M. It allows the device to initialize configuration parameters from the bootstrap server when it first powers-on.
BS with DTLS Bootstrap - Secure 15684 The secure version of Bootstrap uses Datagram Transport Layer Security (DTLS).
MQTT Message Queuing Telemetry Transport 1883

A lightweight messaging protocol for data transfer to/from IoT devices that is optimized to minimize network bandwidth consumption. MQTT is designed for event-driven interactions with objects that measure physical quantities such as light, gas, temperature, dust, motion, sound, and pressure.

MQTT TLS/SSL Message Queuing Telemetry Transport - Secure 8883 The secure version of the MQTT protocol uses Transport Layer Security (TLS)/Secure Socket Layer (SSL) to provide a secure connection.


Over-the-Air Not Applicable Over-the-Air updates facilitate device firmware updates. OTA refers to the methods for distributing software, configuration settings, and updating encryption keys.
