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