@Sissilo In the guide you indicated to me I find nothing that can help me. The switch is connected to a router that has VLAN port 2 in trunk mode. I have port 24 of the tp link switch configured in vlan 2 trunk Now configure as native or primary or default..... vlan2 and disable vlan 1    Please help me. Show the command line.....

  @Sissilo 

i'm not quite sure what you're trying but to disable vlan1 it's this command

no switchport general allowed vlan 1
 

  @Sissilo Ok now I'll give it a try and let you know

  @Sissilo Unfortunately, it doesn't work. Error: 'no' is not applicable

  @Sissilo 

then I don't know, dokumentation say this, I use the switch in controler mode but I think the comand is the same

  @Sissilo 

Sorry but I need to see all the complete commands.... Is this how I should write?

SG3428MP(config)#switchport general allowed vlan 1 1-24 untagged

SG3428MP(config)# no switchport general allowed vlan 1

Thank you very much

  @Sissilo 

this is one of my switch port config, vlan 300 is untagged

interface gigabitEthernet 1/0/1
description "cam"
switchport general allowed vlan 300 untagged
switchport pvid 300
no switchport general allowed vlan 1
dot1x mabFmt captal-with-bar
dot1x port-control authorized-force
dot1x port-method port-based
 

  @Sissilo 

So for my switch could I do this?

interface gigabitEthernet 1/0/1-24
description "none"
switchport general allowed vlan 2 untagged
switchport pvid 2
no switchport general allowed vlan 1

  @Sissilo 

yes if you want vlan2 untagged on all 24 ports, yes. but I don't quite understand what you're going to do, why change all 24 ports to vlan2, do you trunk on the sfp ports? how are your trunk ports?

and mybee you should use interface range like this to configure multiple port

interface range gigabitEthernet 1/0/1-24
