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

Routers
1

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.

@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

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.
