Vlan Mapping Implementations - HP 6125G Configuration Manual

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 service
•
provider network.
For more information about QoS policies, see ACL and QoS Configuration Guide.

VLAN mapping implementations

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.
Figure 59 One-to-one VLAN mapping implementation
One-to-two VLAN mapping
Implement one-to-two VLAN mapping through the following configurations, as shown in
Apply an uplink policy to the incoming traffic on the customer-side port to tag the incoming packets
•
from a certain CVLAN with an outer SVLAN tag.
Configure the customer-side port as a hybrid port, and assign the port to SVLANs as an untagged
•
member. When the port forwards the packets from these SVLANs, it removes their SVLAN tag.
