BUG: VLAN changed no. of Static IP, Router Locks up, Native VLAN changed on Port

I tried to change the number of STATIC assigned IP in a VLAN 20 from 5 to 15.

Route 10 locks up , cant access internet or any local devices. Eventally coouple of minutes later I have access back - set static 15 to 5.

1 AP and 1 Switch offline - cant s, check access admin page, route10 has changed NATIVE VLAN changed from 1 to 20.

Have noticed this happen a number of times, usualy DHCP static IP assignment or Removing a device - The route 10 becomes unresonsive, if recovers great - NATIVE VLAN has changed on one or more ports, or needs are reboot or reset.

What firmware version are you running on Route10? There was an issue a few firmware versions ago where changing VLANs causes the ports to reset. Wondering if you are on a bit older firmware.

1.3k

@Quackers We cannot reproduce this here. Can you give more information about what VLAN settings you are using so that we can try to reproduce your issue?

Thanks.

VLAN1. 10.10.10.1/26. 30 Static Lease time 3600
VLAN 15 10.10.15.1/27. 10 Static. Lease time 43200
VLAN 20 192.168.20.1/26 5 Static Lease time (Default)

VLAN 20 Ip address : 192.168.20.2 to 5 , are static on the router

WAN1 , DHCP, VLAN 911
LAN 1: Native = Default, Allowed VLAN = ALL PoE.=ON
LAN 1: Native = 1. , Allowed VLAN = 1. PoE.=ON
LAN 1: Native = 1. , Allowed VLAN = ALL
LAN 1: Native = Default, Allowed VLAN = ALL , Speed Deault

VLAN 20 - 3 devices setup with static IP on teh console : ip 192.168.20.2 to 5

Can you show a screenshot of your devices screen, and the static address you assigned to one of the clients please?

Please see image:

NOTE this was happening with 1.3k. Router is now on 1.3l

One thing I don’t understand is the VLAN column show 1, 2,4 which map to the real VLANS in use 1,15,20.

Could it be an issue if you set a DHCP assigned device IP to one in reservered static Pool?

VALN 15 10.10.15.1/27

Static reservered = 10
DHCP Pool = 19

Example 10.10.15.26 was assigned by DHCP , set the Static as VLAN 15 with IP of 10.10.15.3 - this casued the Ports to set thier Native to VLAN 15.

Ports Config : ALL TRUNK with VLAN 15, 20 passed as TAGGED

Issue of Router ports VLAN being changed when DHCP assignments are changed.

The router locks up as can’t access anything and the NATIVE LAN has changed from 1 on the TRUNK PORT to 20.

Here is the issue:

All Ports should be UNTAGGED VLAN 1 — Port L1and L3 have been changed to 20 UNTAGGED

Why are DHCP changes on LAN devices impacting the Routers Native VLANS ?

hope this aids fixing this issue.

One possibility: There is a known issue right now where VLAN assignments using colors is NOT working correctly on Route10. They are working on the issue and I imagine it will be resolved quite soon. That being said, as a test would you be willing to change all colors on Route10 back to black, and try setting the VLANs manually on there instead?

Thank You, I will reset and see how things go….

Changed Ip on VLAN 20 (192.168.20.x) from .6 to 14 on

Same issue the something on the route 10 is changing NATIVE VLAN on a LAN port

see:

All ports are COLOR = Black, Manually set Native VLAN and Tagged = ALL

There seems to be another UI bug. If you delete a vlan that was previously configured as a tagged member on a port, you can’t remove it anymore from the allowed vlans menu. It stays there forever unless you add the vlan again, remove it manually from all ports and then delete the vlan.

I am having similar issues on version 1.3s.

Going to devices → device → click port → native VLAN set to something other than default. Making any static IP changes causes it to go back to the default setting, thus losing DHCP for the devices connected via that port.

An observation: It seems that after a day or so the Native VLAN setting seems to stick. Not sure why that is, but if you set the Native VLAN then make any static IP assignments or change the icon of a device (basically any setting that uses the pop up it seems), the Native VLAN would swap back to Default.

same here, router is on 1.3v
I have saved several static IPs for devices, LAN4 supports NATIVE VLAN - it is set to Default, and Allowed, let’s say 150 and 1, i.e. NATIVE (by the way, it turned out that if there is no 1 in ALLOWED, the addressing from this network is not distributed).
I noticed that when I deleting a static IP from VLAN 150, the Native VLAN on the port can change to 150, cutting me off.

We still cannot reproduce anything similar to what is being described here. Can you please give OS, browser, and step-by-step instructions on how to reproduce the issue, even if it is a very short list, please?

Parts in this thread regarding overwriting the ports tagging from devices’ configuration is very similar to my experience reported in thread linked below:

Ok,

Browser: arc
OS: windows 11 pro and MacOS Sequoia
Port 4 on Route10 SFP MM, this port have:
Native VLAN set Default
ALLOWED 1, 150

I Add wired, set serwer at valn150 and address 192.168.150.29, Mac adrress and I save this as static In devices card. Everything’s works ok.
When I delete this it’s cut me off on this port, and when I checked LAN4 via WiFi, APs are on LAN2 and LAN3, LAN4 has in NATIVE VLAN: 150
I use local controller also in VLAN150 maybe here is the problem.

Can you confirm this issue on Chromium and Safari while I continue to narrow down potential culprits?

Hi Josh,

Yes, the problem I described was on the Arc browser, so based on chromium. It was similar on safari.

However, I noticed that if I set the Native LAN port to e.g. 1 or anything else, just NOT Default, everything works as it should, Native LAN does not change.

I understand that Arc is based on Chromium, but based on Chromium is not quite the same as the actual Chromium browser. I use Vivaldi a lot myself, which is based on Chromium, but I sometimes experience bugs that exist on my browser but do not affect Chromium itself.

Thanks for confirming on Safari also.

I’m still looking for minimal steps to reproduce. Can you let me know if the following is accurate?

  1. Configure a client override with a non-default VLAN
  2. Set a static DHCP lease for the same client
  3. Delete the client?
