Datto Networking: Switches: Trunk and access ports



This article describes trunk ports and access ports on Datto Switches.


  • Datto Switches


Trunk ports

Trunk ports connect network equipment such as switches to switches or switches to a router. These types of ports can carry multiple VLANs and will accept 802.1q VLAN-tagged packets.

To set a trunk port on a Datto Switch

  1. Add the desired VLANs to Tagged VLANs
  2. Leave the PVID and Untagged VLANs as 1
The default VLANs in the Tagged VLANs field are 991-994 to allow our APs to talk to each other

Access ports

Access ports connect endpoints in the network, such as a computer or VoIP phone. These ports will designate which VLAN the end client is using.

To set an access port on a Datto Switch

  1. Add the desired VLAN to the PVID and Untagged VLANs fields. These two fields should almost always match.
  2. You can leave the default Allowed Tagged VLANs as is.
Do NOT remove VLAN ID 1 (the management VLAN) from the PVID and Untagged VLANs columns of the ports that are used for uplink, as this will result in the switch not checking in with Datto Networking Cloud Management anymore.
