Introduction

This document provides examples of adding or modifying VLAN tags by using VLAN mapping.

Prerequisites

The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of H3C VLAN mapping.

Example: Configuring one-to-two VLAN mapping

Network configuration

As shown in Figure 1:

·          Customer A and Customer B each have two branches that require Layer 2 connectivity over the service provider network.

·          Both customers have three types of traffic. For each customer, the service provider assigns one SVLAN by traffic type.

Configure one-to-two VLAN mapping on each customer-side port of PE A and PE B to meet the following requirements:

·          The service provider adds an SVLAN tag to packets from customer networks based on the traffic type, as described in Table 1 and Figure 2.

·          The SVLAN tag uses the same 802.1p priority as the CVLAN tag.

Figure 1 Network diagram

 

Table 1 VLAN mapping table

Traffic type	CVLANs	SVLAN
Customer A
Video	31 to 40	1003
Voice	21 to 30	1002
Data	10 to 20	1001
Customer B
Storage	36 to 40	2003
Voice	26 to 35	2002
Data	15 to 25	2001

 

Figure 2 Required traffic pattern in the service provider network

 

Analysis

To support multiple SVLANs and send traffic to the customer networks with the SVLAN tag removed, perform the following tasks on the customer-side ports:

1.        Configure the link type of the ports as hybrid.

2.        Assign the ports to the SVLANs as untagged VLAN members.

For the SVLAN tag to use the same 802.1p priority as the CVLAN tag, configure the customer-side port to use the 802.1p priority in incoming packets for priority mapping.

Restrictions and guidelines

When you configure ports on the forwarding path of double-tagged packets across the service provider network, follow these restrictions and guidelines:

·          Set the MTU to a minimum of 1504 bytes for each port.

·          Configure all ports to allow double-tagged packets to pass through without removing the SVLAN tag.

Example: Configuring two-to-two VLAN mapping

Network configuration

As shown in Figure 3:

·          A company assigns its branch sites (Site 1 and Site 2) to VLAN 10, and the headquarters provides services in VLAN 30.

·          Service provider A uses SVLAN 100 to transmit VLAN 10 traffic for the branch sites.

·          Service provider B uses SVLAN 200 to transmit VLAN 30 traffic for the headquarters.

Configure two-to-two VLAN mapping to permit the two branch sites to access VLAN 30 of the headquarters without changing their VLAN assignment.

Figure 3 Network diagram

 

Restrictions and guidelines

Configure two-to-two VLAN mapping on one of the edge devices between the two service provider networks. This example uses Switch C.
