Configuring Two-To-Two Vlan Mapping - HP 5820X series Configuration Manual

To do...
4. Assign the port to CVLANs
and SVLANs
5. Enable customer-side QinQ
6. Apply the uplink policy to the
incoming traffic
Before applying a QoS policy to the customer-side port, enable customer-side QinQ on the port. Before
disabling customer-side QinQ on the customer-side port, remove the QoS policy from the port first.
Configuring the network-side port
To configure the network-side port:
To do...
1. Enter system view
2. Enter Layer 2 Ethernet
interface view
3. Configure the port as a trunk
port
4. Assign the port to SVLANs
5. Configure the port as a DHCP
snooping trusted port
6. Configure the port as an ARP
trusted port
Enable network-side QinQ
7.

Configuring two-to-two VLAN mapping

Perform two-to-two VLAN mapping on an edge device that connects two SP networks, for example, on PE
3 in Figure 59. Two-to-two VLAN mapping enables two remote sites in different VLANs to communicate at
Layer 2 across two service provider networks that use different VLAN assignment schemes.
For the ease of description, the VLAN tags of the double-tagged frames that arrive at the customer-side
port are called foreign CVLANs and SVLANs, and the VLAN tags marked by the edge device are called
local CVLANs and SVLANs.
Perform these tasks to configure two-to-two VLAN mapping:
Use the command...
port trunk permit vlan { vlan-id-list
| all }
qinq enable downlink
qos apply policy policy-name
inbound
Use the command...
system-view
interface interface-type interface-
number
port link-type trunk
port trunk permit vlan { vlan-id-list
| all }
dhcp-snooping trust
arp detection trust
qinq enable uplink
