DHCP Discover/Offer Loop

Installing and Using OpenWrt
1

Hello!
Can anybody help me point to a direction to solve this?

These few logs is my PS4 Ethernet Cable trying to get an IP addres bur not sendind DHCPACK. The PS4 is connected to a 8-port switch and the switch connected to the OpenWRT LAN,
If I manually configure an IP address, the PS4 connects to the network but DHCP won't work!
I had the same loop problem on a VM runing on a NAS but I thought that could be related do VM or NAS and did not give much attention...

I found some other topics, like this: Certain devices ignore DHCPOFFER

But its sollution was some option parameter on mwan3... I don't use mwan3... I even installed the packege and added that parameter but there was no difference...
If I try to connect the same PS4 on WLAN (bridged to the same network), it get an IP address successefully.
I'm completly lost on this....

Coul'd this be related to multiple DHCP clients on the same ethernet port?

Thanks..

this is typically the result of an option mismatch anomaly between client and server...

tcpdump capture and compare requested and sent options...

in your case though... i'm suspecting something else... openwrt version / model?

I was suspecting that was some mismatch between client and server but the same device works fine on wifi...

This is my device info:

Model:	Xiaomi Mi Router 3 Pro
Architecture:	MediaTek MT7621 ver:1 eco:3

Kernel Version: 5.4.111

I did another test and it seems to be switch related...

I disconnected the cable from router LAN3 to the switch:

i'm going to take the easy option for now and confirm your firewall is default and no fancy switch, static options anywhere?... if so... chances are it (being an assumed stack-ish bug) might be fixed in master already...

not sure if chef libremesh is functional right now so you can easility build a 21.02-SNAPSHOT/master image with luci ( think it is at least for master ) you should def upgrade to master would be best and see if persists,,.

also stating the device (PS4) firmware version might be relevant here...

before posting, I did disable firewall for br-lan and got the results...
I do use some fancy switch stuff :stuck_out_tongue_winking_eye:.
Sorry not to mention that but I did a lot of config and I don't know what is relevant for this issue or not.
I have 3 main interfaces (lan, iot and guest) and BATMAN mesh to other AP. Here is my network info:

config interface 'loopback'

definately relavent (config is like a belly button better out than in... actually I prefer inn-ies but the analogy wont work that way)... my recommendation to upgrade still stands... but in light of the above 21.02.0-rc2 may be more suitable (we posted at the same time glad you pinpointed some odd switch-ish level behavior) ... don't keep config ( make a backup ) then slowly reapply stuff... checking as you go... (post ypur firewall config too)

by this time someone may spot your foibles (specific area that is whacky) and give you some pointers...

I upgraded to OpenWrt 21.02.0-rc2 r16122-c2139eef27 a created te interfaces all over again.
It solved the problem... I don't know why...

This this version the config is different... don't use "option ifname" anymore and the bridge references are now under "config device" and no more under "config interface".

config device
        option name 'br-lan'
        option type 'bridge'
        list ports 'lan2'
        list ports 'lan3'
        list ports 'bat0.1'

config device
        option name 'br-iot'
        option type 'bridge'
        list ports 'lan1'
        list ports 'bat0.107'

config device
        option type 'bridge'
        option name 'br-guest'
        list ports 'bat0.30'

config interface 'lan'
        option device 'br-lan'
        option proto 'static'
        option ipaddr '192.168.1.1'
        option netmask '255.255.255.0'
        option ip6assign '60'

config interface 'iot'
        option proto 'static'
        option device 'br-iot'
        option ipaddr '192.168.9.1'
        option netmask '255.255.255.0'

config interface 'guest'
        option proto 'static'
        option ipaddr '192.168.30.1'
        option netmask '255.255.255.0'
        option device 'br-guest'
