Implementing Vlan Mapping - HP A5830 Configuration Manual

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 the service provider network.

Customer-side port—A port connected 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 service

provider network.
For more information about QoS policies, see ACL and QoS Configuration Guide.

Implementing VLAN mapping

This section describes how VLAN mapping is implemented on your device.
One-to-one VLAN mapping
Implement one-to-one VLAN mapping on the customer-side port through the following configurations, as
shown in Figure
Apply an uplink policy to the incoming traffic, mapping each CVLAN ID to a unique SVLAN ID.

When a packet arrives, the switch replaces its CVLAN ID with the matching SVLAN ID.
Apply a downlink policy to the outgoing traffic, mapping each SVLAN ID back to its corresponding

CVLAN ID. When forwarding a packet out of the port, the switch replaces its SVLAN ID with the
matching CVLAN ID.
