R9000 has a odd switch layout, combined by 2 switches..
as far as i know eth0 must be the SFP port...the only one that you can segregate as separate VLAN...
and by default its bridged with vlan1 where there are the radios, and the aggregated ports eth2 and eth1 if im not wrong...

and your macs lay out is ok...in my case by default my lan_hwaddr mac was same as wlan2 witch is the 60Ghz radio Razz.. so, i had to change it..via commands...still no idea why my R9000 defaults with wrong mac's it could be because i first flashed it with Kong build...still need to investigate...

Due to suspected ISP restrictions, I too tried mac clone on my R9000 and ran into to crazy mac's. Never could get it working. So, let's try stock.

Had to reset/reflash original at least twice + test, reset/nvram erase/reload ddwrt twice. Finally the leftover mac from clone attempt was gone.

DHCP now works. Success

Update: and then it doesn't

Update 2: and it works again.
I think my ISP is scr***** with me

Ah... I did not know the startup script changes would make the nvram set commands moot. Good to know. Originally I noted that my changing of the mac didn't reflect in the GUI, so I did that as a measure to insure I didn't confuse myself in the future. My R9000 does a lot for me and I have configs and scripts doing all sorts of things.

Anyway, as requested, here is the output you requested. I still have my override in there. Ended up changing the mac to a virtual nic from an ESXi VM I was going to delete.

Code:
~# nvram show | grep hwaddr
eth0_hwaddr=00:0C:29:EE:98:E3
size: 45764 bytes (85308 left)
eth1_hwaddr=78:D2:94:41:7A:18
eth2_hwaddr=00:0C:29:EE:98:E3
def_hwaddr=00:0C:29:EE:98:E3
wan_hwaddr=78:D2:94:41:7A:19
vlan1_hwaddr=78:D2:94:41:7A:18
lan_hwaddr=78:D2:94:41:7A:18
wl_hwaddr=
nvram set eth0_hwaddr="00:0C:29:EE:98:E3"
nvram set eth2_hwaddr="00:0C:29:EE:98:E3"
def_whwaddr=78:D2:94:41:7A:1A
wlan0_hwaddr=78:D2:94:41:7A:1A
wlan1_hwaddr=78:D2:94:41:7A:1B
wlan2_hwaddr=8C:45:00:21:2B:31


Another question. Considering eth0 and eth2 share the same mac, if I clone to an address for something active on my network, will that cause a conflict. VLAN2 is the WAN port so it won't matter since it is segregatedon the WAN side, but I was unsure of eth0 and eth2, because eth0 is in a bridge with VLAN1. I ended up opting to use a mac address that was no longer going to risk being used on my network, just in case.


The original issue still exists in 2022.
I have used this firmware https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2022/01-21-2022-r48141/netgear-r9000/

Thanks for sharing a fix @ktuimala . It was very helpful to save some time.

on my R9000 i successfully managed to change any of my interfaces belonging MAC addresses using those guidelines form here, sadly those have to be redone after reset...
