BPDU/STP Errors
I am experiencing BPDU/SPT errors on from my Orbi. This causes my Netgear GS324 switch to lock out the port administratively. To recover I must then manually re-enable the port.
The Orbi is connected to the switch on two ports, G1 and G23. G23 is an unrouted vlan for outside the firewall traffic, G1 is the orbi LAN. One satellite is directly hardwired to the Orbi.
This is what a normal downstream device power failure looks like.
Note: G15 is a downstream netgear switch.

I am confused. The Netgear GS324 is an "unmanaged" switch, which in my limited experience means it knows nothing about VLANs.
If two of the Orbi LAN ports are connected to the same switch, that seems like a textbook example of a spanning tree problem.
It might help get an informed response if you could provide a rough diagram of how this is all set up.
The OP must talk about the S350 Series GS324T or GS324TP, neither the unmanaged GS324, nor a GS324E model variant.
Best guess, there is some rate limit configured on the port why ever, this isn't the problem here.
In connection with Orbi, there is no other choice than using the (off-standard!) legacy STP and define a prio aka ID of 32768 on switches supporting STP/RSTP/MST.
What happens is that the Orbi STP - core part of the Orbi design - does override the (undoubted technically better) Gigabit Ethernet backhaul so the switch will close the port to avoid a loop.
Relevant is the information that STP and RSTP is valid for the complete network layout, and isn't restricted to a VLAN like the much more advanced MST (requiring more know-how to configure) and offering RSTP at the edge. Said that - Orbi == STP only.
Edit. Interesting are the logs do talk about MST (MSTID) - is the switch configured to operate with it? What Orbi model and firmware version are we facing here? Is this a set-up which worked before, or was the switch added recently, or was it reconfigured?
My apologies, you are correct. the device is a GS324T S350 Series 24-Port Gigabit Ethernet Smart Managed Pro Switch
Orbi is
Hardware Version RBR50
Firmware Version V2.3.5.30 / GUI Language Version V1.0.0.375
It was working previously, with a Cisco SRW2024 switch. No idea if STP was enabled as the console never functioned properly and I used it as if it was a dumb switch. The port being disabled begain with the GS324T.STP Config is as follows:
