shows a simplified network to help explain the concepts and terms that you might
encounter when you work with VLAN mapping.
Figure 57 Basic concepts of VLAN mapping
•
Uplink
traffic
—Traffic transmitted from the customer network to the service provider network.
•
Downlink
traffic
—Traffic transmitted from the service provider network to the customer
network.
•
Network-side
port
—A port connected to or closer to the service provider network.
•
Customer-side
port
—A port connected to or closer to the customer network.
•
Uplink
policy
—A QoS policy that defines VLAN mapping rules for uplink traffic.
•
Downlink
policy
—A QoS policy that defines VLAN mapping rules for downlink traffic.
•
Customer VLANs (CVLANs)

•
Service provider VLANs (SVLANs)
—VLANs assigned for transmitting traffic across the
