When the Omada controller discovers an Omada device.

The running controller sends information about itself to TCP port 27002 of the initializing controller.

A running controller, if any, listens on the port and receives the message. The initializing controller sends a self-introductory message to UDP port 27001 of every host in the LAN. A conversation takes place as shown in the following figure and table. Otherwise, it stops initializing and launches the web page of the running controller instead. When an Omada controller initializes, it should confirm that no other controller is running in the LAN.

Initialization Check (Only for Controller Software V3).

In this section, we take two examples to explain how Omada Controller uses ports. Before Controller Software V3.0.0, TCP 27017 is used instead. TCP 27217 is used to access the built-in database for Controller Software V3.0.0 or later version. The Omada Software Controller accesses the built-in database. (Only for Omada Software Controller v3.2.4 and before version. This port has been discarded in the later version) Gather information about another controller in the LAN. In Omada Controller v4.x and later version, this port is mainly used for discovering the Omada Controller in the LAN by Omada App. Check whether another controller is running in the LAN during initialization.

Such fact gives rise to a port collision when a program tries to use a certain port on a host, only to find the very port is occupied by another program.įrom this article, you can learn which ports an Omada controller and an EAP Discovery Utility use, and how to troubleshoot a port-related problem when it happens. Port numbers are limited, ranging from 1 to 65535 among each group. Ports fall into two groups: TCP (Transmission Control Protocol) ports and UDP (User Datagram Protocol) ports. An Omada software controller or EAP Discovery Utility uses the ports on the host, while an Omada hardware controller uses the ports on its own hardware. Programs use specific ports to send or receive data via a network.
