EDUP EP-RT2960 AX1800 - Is it vlan capable?

[Bingo]

OpenWRT newbie alert.

I just bought a EDUP EP-RT2960 AX1800
And after goofing + recovery.

Guide - EDUP EP-RT2960 AX1800 - Recovering from a : mtd erase

EDUP EP-RT2960 AX1800 - Recovering from a : mtd erase --------------------------------------------------------------------------------- I'm yet another "newbie" that bought an EDUP 2960 AX180 router w. a factory openwrt installed. Foolishly enough i followed the guide here, as best as i could understand it. I tried via luci to flash the "factory" image, but the router didn't seem to take it. Unfortunately i never thought of trying the sysupgrade image at that point ... (newbie) Bricking t…

I now have it running OpenWRT 24.10.0
It will be deployed as an AP , aka ... "pure wifi/lan bridging" , no use for WAN port.

I haven't had much time to play around yet (see above)
I was wondering if this box is vlan capable ?

I had a look at the wiki , and have run a few commands

Can anyone determine if it's capable from the above ??

Another thing (nuisance) :
Whenever i reboot the router it changes the LAN MAC Address
Is that a "Router/uboot feature" or an OpenWRT "feature" ?

While that might be nice for some, i read about security.
It's a nuisance if you as i, prefer to set ip via "Mac locked dhcp".

Can i disable it, at least for LAN ?

Or is there a hint to set a "static" MAC - "Locally administered will be ok".

most likely a "bug feature".

you can override it in the interfaces -> devices settings, to get it to match the label.

It is an MT7621 chip, those were one of the first to be converted to DSA and it has full VLAN support.

[Bingo]

Thank you ... It seems to be that chip.

I can see that the same mac is (was) set for 4 devices:

br-lan
eth0
lan1
lan2
lan3

I have now changed the mac to static on the bridge.
Should i give the other interfaces the same "static mac" as the bridge has gotten ?

Any hints on the eth0 and Lan relations , for this chip ?

I mean i "suppose" lan1..lan3 might be switch ports (L2)

So eth0 is the ether if (L3) , and might be inside the MCU/SOC.
This would make this a "classic L2/L3 setup" I think.
L2 ports forwarding packets to an "upstream L3 IF".

I just don't know why they all have the same MAC , unless it's inheritance from the bridge or eth0 if. And i just tried to change the bridge mac, it didn't change the other.
