AX3000v2 cant find lan port ids in cli

[kakashisensei]

I am running gnuton fork of asusmerlin on my AX3000v2 (AX58v2) in AP mode with AI mesh nodes attached. I have an issue where one lan port degrades from 1gb to 100mb randomly. I can't change the wire or other stuff that might be causing it. I rather just have a script monitor it and reset the connection, like this one.

However, I am having difficulty identifying any of the lan port devices in cli. This is what I get when I do brctl.

AX3000_MAIN:/# brctl show
bridge name     bridge id               STP enabled     interfaces
br0             8000.08bfb852c258       no              eth0
                                                        eth1
                                                        eth2
                                                        eth3

Eth0 is wan. I suspect Eth1 is wifi. I am not sure what eth2 or eth3 are. Ethctl does not pull up anything on Eth2 or Eth3, giving me a ioctl SIOCGQUERYNUMPORTS error, even when I specify a subport. I have tried all ethctl commands on eth2 and eth3 including powering down, but it just returns errors or SIOCGQUERYNUMPORTS error.

I suspect the lan ports are under br0, but none of the ethctl commands work with it.

Does anyone have experience with this or some pointers? Much appreciated.
