Vdsl Vlan Setup - ZyXEL Communications MSC1024G Series User Manual

Chapter 11 Subscriber Port Setup Screens
TPID (Tag Protocol Identifier) is the customer IEEE 802.1Q tag.
Priority refers to the IEEE 802.1p standard that allows the service provider to prioritize traffic
based on the class of service (CoS) the customer has paid for.
• On the switch, configure the priority level of the inner IEEE 802.1Q tag in the Port Setup
screen.
• "0" is the lowest priority level and "7" is the highest.
VID is the VLAN ID. SP VID is the VID for the second (service provider's) VLAN tag.

The frame format for an untagged Ethernet frame, a single-tagged 802.1Q frame (customer)
and a "double-tagged" 802.1Q frame (service provider) is shown next.
Configure the fields as circled in the switch VLAN Stacking screen.
