Configuring One-To-Two Vlan Mapping; Configuring Two-To-Two Vlan Mapping - HP FlexFabric 12900 Series Configuration Manual

Step
4. Assign the port to the original
VLANs and the translated
VLANs.
5. Configuring a one-to-one
VLAN mapping.

Configuring one-to-two VLAN mapping

Configure one-to-two VLAN mapping on the customer-side ports of edge devices from which customer
traffic enters SP networks, for example, on PE 1 and PE 4 in
enables the edge devices to add an SVLAN tag to each incoming packet.
Before you configure one-to-two VLAN mapping, create the CVLAN and the SVLAN.
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. HP recommends setting the MTU to a minimum of 1504 bytes for ports on the
forwarding path of the packet in the service provider network.
To configure one-to-two VLAN mapping:
Step
1. Enter system view.
Enter Layer 2 Ethernet
2.
interface view or Layer 2
aggregate interface view.
3. Configure the link type of the
port as hybrid.
4. Assign the port to the
CVLANs.
5. Assign the port to the SVLANs
as an untagged member.
6. Configure a one-to-two VLAN
mapping.

Configuring two-to-two VLAN mapping

Configure two-to-two VLAN mapping on the customer-side port of an edge device that connects two SP
networks, for example, on PE 3 in

Remarks
By default, a trunk port is
assigned to only VLAN 1, and
a hybrid port is only an
untagged member of VLAN 1.
By default, no VLAN mapping
is configured on an interface.
