Meraki Switch: 'STP Discarding Packets' error.

[Philj]

Hoping someone can help...

I connected my Sonos kit to a Meraki switch, everything works, but I'm getting these messages/errors:

RSTP: Blocking (Client is using legacy STP)

and

RSTP is in use and the port is discarding traffic because it would introduce a switching loop

What does this mean? Is there any way to get rid of the messages or isn't it anything to be concerned about?

Thanks

Does it have multiple ethernet ports connected to the Sonos device?

Is it connecting via wireless and wired at the same time? Try disabling wireless if it does.

The message is saying you have a network loop and it disabled one if the ports to prevent a loop.

Do you have multiple Sonos devices connected together that also connect to the switch and to each other via wireless?

Although there are two network ports on each Sonos device, only one of them is in use.

Although there are two network ports on each Sonos device, only one of them is in use.

Disable the wireless between the devices or unplug the other devices. Sonos devices create a mesh type network between each other so only one needs connectivity to the network. Either wire them all and disable the wireless part or wire one and have the rest connect wirelessly.

Or just ignore the error as STP is doing what it's supposed to. That error is "to be expected" on a managed switch that has STP.

Sorted! Although connected via LAN cable, it was still transmitting via SonosNet.

To deactivate SonosNet, you run the following command:
