VLAN Stacking Example
8.3 VLAN Tag Format
A VLAN tag (service provider VLAN stacking or customer IEEE 802.1Q) consists of the
following three fields.
Type
is a standard Ethernet type code identifying the frame and indicates that whether the
frame carries IEEE 802.1Q tag information.
SP TPID
(Service Provider Tag Protocol
Identifier) is the service provider VLAN stacking tag type.
Many vendors use 0x8100 or
0x9100.
Priority
refers to the IEEE 802.1p standard that allows service providers to prioritize traffic
based on the class of service (CoS) the customer has paid for.
• On the OMC, configure priority level on inner IEEE 802.1Q in the
VLAN Profile
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.
8.3.1 Frame Format
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.
