Vlan 1 can not be modified

I recieve this error when trying to remove a port from Vlan 1. I want to put this port, and a few others, in a new Vlan.



 



but after I click the port, which turns from blue to white, I click Apply, then this message comes up:



Vlan 1 can not be modified



 



Any ideas?



 



thanks

Re: Vlan 1 can not be modified

Hello,



i dont know how to do this with web access,



but in command line i think you need to change the pvid from one to something else



as long as the vlan 1 is the default native vlan, you cant change it.



/copied from post of Fred M /



port link-type trunk



port trunk pvid vlan 999



port trunk permit vlan <vlan_id>list>



In access ports:



port access vlan 999



In hybrid ports:


 



port link-type hybrid



port hybrid vlan 999 untagged


 



undo port hybrid vlan 1 untagged

Sounds complicated, I am more of a GUI guy. I apprecitate the insight anyway.

Re: Vlan 1 can not be modified

Hi fellas.



This occurs because the VLAN 1 is the default VLAN, which means that it cannot be removed or deleted. In your case, that is working with web browser console, you have to assign a new VLAN to the port you want, and set it as UNTAGGED. After this, only this new VLAN will be forwarded in the port. If you set the new VLAN as tagged, you will permit the VLAN 1 to pass untagged and the new VLAN to pass tagged.



After this custom settings, the new VLAN will be the PVID of the port.



Regards
