Resolve a network loop warning on a Pleneo hub

Why a switch may warn about a loop on a Pleneo hub, and how to fix it.

Overview

Pleneo hubs have two independent, fully isolated ports, with no bridging or forwarding between them:

  • LAN 1: control and management

  • LAN 2: audio and video

When both ports land on the same broadcast domain, some switches read this as a loop and raise a warning.

Fix it 

Connect the two ports to separate networks:

  • Connect LAN 1 to the control or corporate network

  • Connect LAN 2 to the dedicated audio and video network

Tip: if you're not using the audio and video network yet, disconnect LAN 2 and run RoomHub on LAN 1 only while you set the rest up.

Result 

Keep LAN 1 and LAN 2 on separate networks, and the loop warning goes away; Pleneo hub works as expected.
