Cisco SG200-26 which VLAN mode

lukass2000

Hello,
I bought a Cisco SG200-26 and am currently setting up the VLANs.
Is my first Cisco router, therefore something new.
Now i have a question:
By default, the VLAN mode is set to "Trunk" everywhere (as can be seen in screenshot1).
On the Cisco, the Port24 is connected to a second managed switch (a Netgear GS116e) with a LAN cable in the attic.
Each port is automatically set as a "trunk".
Shouldn't it be not better to set only Port24 as trunk on the Cisco, since all VLANs are to be transmitted there and to set all other ports to "Access"?
That should be possible to change (as can be seen in screenshot2)?
Or does it matter if all ports are set as trunk?
Thanks

           - As you say, confirmed , use trunk-links (ports) only where needed.

Hi @marce ,
thanks for the information
But i don't understand why is standard always "trunk"?
Also saw this Cisco video.
You can also see the basic setting is always "trunk"?
Thanks

 

  - This is only an unfortunate 'delivery default' set according to your needs and or disable trunk where no trunk links are needed.

Hi Lukass,

 

This is the default VLAN configuration of Sx200 switches and that is by design.

 

"Default VLAN Settings
When using factory default settings, the device automatically creates VLAN 1 as the default VLAN, the
default interface status of all ports is Trunk, and all ports are configured as untagged members of the
default VLAN."
