11.31 xVLAN

xVLAN translates (changes) VLAN IDs. xVLAN changes the VLAN IDs (VIDs) of
subscriber traffic before sending it to the service provider's network. It also changes the VIDs
of traffic from the service provider's network before sending it to the subscriber. This lets you
use unique VLANs for each subscriber but still deploy all the CPE devices with the same
VLAN configuration. xVLAN on the VLC13XXGs also supports translating single-tagged
frames to double-tagged frames. This is similar to what is known as VLAN stacking or Q-in-
Q. See Section 11.8.7.1 on page 237
double tagged frame formats.
In the following figure CPE devices A and B both add VLAN tag 1 to voice traffic, tag 2 to
video traffic, and tag 3 to data traffic. xVLAN separates these VLANs within the Service
Provider's Network (SPN) by translating A's VLAN tags to 11, 12, and 13 and B's VLAN tags
to 21, 22, and 23. The advantage is that both CPE devices have the same VLAN configuration,
therefore reducing CPE device configuration complexity.
