Hi - looking for some information about how Orbi uses the STP/BPDU protocols. Can't find any via google, so hoping that someone here knows more. I am using an Orbi RBK50 in AP mode plugged into a Ubiquiti EdgeSwitch. The Edgeswitch is reporting a BPDU error from the Orbi as below: Jul 24 04:47:44Errordot1sBpduReceive(): Discarding the BPDU, since it is an invalid BPDU typeJul 24 04:47:44Noticedot1sBpduReceive(): Invalid Forward DelayJul 24 04:47:42Errordot1sBpduReceive(): Discarding the BPDU, since it is an invalid BPDU typeJul 24 04:47:42Noticedot1sBpduReceive(): Invalid Forward Delay It's been suggested to me on the Ubiquiti forums that I need to either change/disable the STP mode on the Orbi or adjust the "Forward Delay". However, I can find no ability to do so in the Orbi UI. Questions: 1. Is there any ability to adjust or disable the STP/BPDU settings on the Orbi?2. What are the default settings for the STP/BPDU protocols on the Orbi? Thanks. -Robert

It's been a while since I updated this thread as life interfered, but thought I would provide an update for those interested. 1. I have tried the various suggestions for blocking STP at that port of the edgeswitch without any success. I believe I am following the instructions from the ubiquiti support correctly, but there is no change in behavior. That said, the advice from the ubiquiti site is that blocking the STP commands on that port will result in marginal if any improvements in performance, so I have decided to stop pursuing this issue until when/if Orbi firmware with ethernet backhaul support is released. (I continue to assume this will involve changed STP functionality on the Orbi side, but we shall see.) 2. I have installed my Sonos system. About a dozen components, some wired and some wireless. Amazingly enough, everything just worked with no attempt to do anything other than install the speakers using the sonos app. Thanks for the various comments and help, I look forward to paying it forward. -Robert

I don't have your answer, but I do have an RBR50 in AP mode plugged into a Ubiquiti US-8-150W switch. This is similar to the Edgeswitch. No STP issues with that, that I am aware of anyway. Are you certain it's the Orbi causing the errors? Also, what exactly do you have plugged into the switch. RBK50 is the part number for the kit. Is it the the router or the satellite that's plugged into the switch?

It's the router that's plugged in to the Edgeswitch, though again operating in AP mode. I believe it is the Orbi router that is causing the problem as the error messages stop when I unplug the router and resume immediately when I replug the router. I've not plugged the satellites in yet, so can''t comment on whether they also generate this error. I know that the Ubiquiti Unifi switches are slightly different than the Ubiquiti EdgeMax switches, but I'm not familiar with the details. My system is working, in the sense that wireless devices can connect via the Orbi Router and work fine. It's only when I inspect the system logs on the EdgeSwitch that I notice this error. When you say your system has no issues, have you looked at the system log? Thanks! -Robert

Thanks for the further detail. I expect that plugging-in the satellites would cause issues, such as a network loop. That's why I asked. I looked at the "Events" in the Unifi controller and don't see any errors noted there. I'll need to SSH into the switch to see if there is a log there analagous to the Edgeswitch. There's no GUI on the Unifi switches.

I logged into the switch via SSH and looked at the log in /var/log/messages. No spanning tree errors. Plenty of messages about the spanning tree config changing, and a new root being selected, etc. I have a Sonos system, which uses STP, so it just looks like normal STP operations..

Orbi STP/BPDU errors

Hi - looking for some information about how Orbi uses the STP/BPDU protocols. Can't find any via google, so hoping that someone here knows more.

I am using an Orbi RBK50 in AP mode plugged into a Ubiquiti EdgeSwitch. The Edgeswitch is reporting a BPDU error from the Orbi as below:

Jul 24 04:47:44	Error	dot1sBpduReceive(): Discarding the BPDU, since it is an invalid BPDU type
Jul 24 04:47:44	Notice	dot1sBpduReceive(): Invalid Forward Delay
Jul 24 04:47:42	Error	dot1sBpduReceive(): Discarding the BPDU, since it is an invalid BPDU type
Jul 24 04:47:42	Notice	dot1sBpduReceive(): Invalid Forward Delay

It's been suggested to me on the Ubiquiti forums that I need to either change/disable the STP mode on the Orbi or adjust the "Forward Delay". However, I can find no ability to do so in the Orbi UI.

Questions:

1. Is there any ability to adjust or disable the STP/BPDU settings on the Orbi?

2. What are the default settings for the STP/BPDU protocols on the Orbi?

Thanks.
