Trunk port : A trunk port carries VLAN traffic across switches:
•
– A trunk port in a PVLAN is always tagged.
– Primary or secondary VLAN traffic is carried by the trunk port in Tagged mode. The tag on the packet
helps identify the VLAN to which the packet belongs.
– A trunk port can also belong to a regular VLAN (non-private VLAN).
