Gs305 cascading

Hello

What is the best configuration

I have two gs305 connect via port 5

 

I am using advanced vlan port tagging

 

Port 1-3  vlan

port 4 vlan 5

Port 5 vlan 1 and 5

 

Or is 802.1q the better configuration?

 

Thanks for the info

Udo

    Some kind of GS105E, GS105EP, GS105EPP, GS105Ev2, or similar - as a GS105 is an unmanaged switch, and you won't have these options - one might guess.

    Definitivley yes!

     

    Talking of the advanced 802.1q mode here:

     

    That way you can operate the trunk (where you intend to transport more than a single VLAN on might guess) the way you prefer, e.g. the VLAN 1 as [U]ntagged (don't forget to set the PVID for the trunk ports to 1), all other VLANs als [T]agged. 

     

    Of course, you might consider going to the basic 801.1q mode. Disadvantage for the trunk port: You can't simply connect any computer for testing - on that trunk mode, all VLANs on the trunk ports will be tagged.
