Forwarding Tagged/Untagged Frames - Planet Networking & Communication WGS3-2620 User Manual

6.3.2 Forwarding Tagged/Untagged Frames

Ports can be assigned to multiple tagged or untagged VLANs. Each port on the switch is therefore
capable of passing tagged or untagged frames.
To forward a frame from a VLAN-aware device to a VLAN-unaware device, the switch first decides where
to forward the frame, and then strips off the VLAN tag. However, to forward a frame from a
VLAN-unaware device to a VLAN-aware device, the switch first decides where to forward the frame, and
then inserts a VLAN tag reflecting this port' s default VID.
The default PVID is VLAN 1 for all ports, but this can be changed.
