Hi there,
When I load the config attached, if I go into VLAN management afterwards, GE12, LAG 1 and LAG 2 have lost all their tagged VLAN settings. This has happened a couple of times now or when I reboot the switch, the problem arises again. GE12 for example now just has 65UI there and not 60-64T. If I then pull a backup file from the switch now, the config will now say 'switchport trunk port allowed vlan none' under GE12. I have also tested the config once I have uploaded it and it doesn't work.
I am aware VLAN 65 is inactive but we only need one port on this switch, then on the other end there could be a port with 65U to attach a Ubiquiti cloudkey for example so I assume this isn't the problem.
Love any explanation or insight to why this is happening. Is there something obvious I'm missing in the config?
Many thanks,
Elliot

Helllo @elliots ,
There are inconsistency configuration on your file.
I suggest you allowed just vlans that you need instead use remove command
interface GigabitEthernet12
switchport mode trunk
switchport trunk native vlan 65 /
switchport trunk allowed vlan remove 1-59,65-4094 << try change switchport trunk allowed vlan 65, but if this post is part of LAG 1 or 2, the same command is necessary on LAG
!
interface Port-Channel1
description ASR_LAG1
switchport mode trunk
switchport trunk native vlan 99
switchport trunk allowed vlan remove 1-9,11-59,71-4094
!
interface Port-Channel2
description ASR_LAG2
switchport mode trunk
switchport trunk native vlan 99
switchport trunk allowed vlan remove 1-9,11-59,71-4094

Hi,
Edited:
It looking the Native VLAN of Port 12 and Port-channel 2 are also removed.
interface Port-Channel1
description ASR_LAG1
switchport mode trunk
switchport trunk native vlan 99
switchport trunk allowed vlan remove 1-9,11-59,71-4094
!
Check again the configuration.

Hi,
I am not sure what was happened but here is a page which will help you to get all the details about the VLAN.
Login in the Switch--->VLAN Management--->Port VLAN Membership--->Select desire Port-->Join VLAN--->and Change VLAN as required.
