Configuring One-To-Two Vlan Mapping - HP 6125XLG Configuration Manual

Step
2. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view.
3. Set the port link type.
4. Assign the port to the
translated VLANs.
5. Configure the port to use the
original VLAN tags of the
many-to-one mapping to
replace the VLAN tags of the
packets destined for the user
network.

Configuring one-to-two VLAN mapping

Configure one-to-two VLAN mapping on the customer-side port of the edge devices from which customer
traffic enters SP networks, on PE 1 and PE 4 in
enables the edge devices to add an outer VLAN tag to each incoming packet.
Before configuring one-to-two VLAN mapping, create the original VLAN and the translated VLAN.
The MTU of an interface is 1500 bytes by default. After a VLAN tag is added to a packet, the packet
length is added by 4 bytes. When you configure one-to-two VLAN mapping, HP recommends that you
set the MTU to a minimum of 1504 bytes on interfaces in the service provider network. For more
information about the MTU, see
To configure one-to-two VLAN mapping:

Remarks
N/A
By default, the link type of a
port is access.
By default, a trunk port is
assigned only to VLAN 1, and
a hybrid port is an untagged
member of VLAN 1.
By default, VLAN mapping is
not configured on an interface.
