Configuring Two-To-Two Vlan Mapping - HP 3600 v2 series Configuration Manual

To do...
Configure the port as a trunk port
Assign the port to SVLANs
Configure the port as a DHCP
snooping trusted port
Configure the port as an ARP
trusted port
Enable network-side QinQ

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
communicate at Layer 2 across two service provider networks that use different VLAN assignment
schemes.
NOTE:
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:
Task
Configuring an uplink policy for the
customer-side port
Configuring an uplink policy for the
network-side port
Configuring a downlink policy for the
customer-side port
Configuring the customer-side port
Configuring the network-side port
Configuring an uplink policy for the customer-side port
The uplink policy on the customer-side port modifies the SVLAN ID of incoming traffic.
Follow these steps to configure an uplink policy for the customer-side port:
Use the command...
port link-type trunk
port trunk permit vlan
{ vlan-id-list | all }
dhcp-snooping trust
arp detection trust
qinq enable uplink
64. Two-to-two VLAN mapping enables two remote sites in different VLANs to
Remarks
Required
The default link type of an Ethernet port is
access.
Required
By default, a trunk port is in only VLAN 1.
Required
By default, all ports are DHCP snooping
untrusted ports.
Required
By default, all ports are ARP untrusted ports.
Required
By default, network-side QinQ is disabled
on all ports.
