VLAN tagging features enable service providers to separate or aggregate customer traffic in the service provider network. The following are available VLAN tagging operations:

· Adding a layer of service provider VLAN (SVLAN) tag.

· Modifying the SVLAN tag, CVLAN tag, or both.

To add an SVLAN tag, use one of the following VLAN tagging features:

· QinQ—Tags all incoming frames (tagged or untagged) on the customer-side port with the PVID of the port.

· One-to-two VLAN mapping—Adds different SVLANs for traffic with different CVLAN tags.

· Policy-based VLAN manipulation—Uses QoS nest actions in a QoS policy to tag different classes of frames with different SVLAN tags. Traffic classifiers include CVLAN ID, IP address, and MAC address. In addition, you can use QoS priority marking to set the 802.1p priority in SVLAN tags.

To modify VLAN tags, use one of the following VLAN tagging features:

· VLAN mapping—Includes the following features:

¡ One-to-one VLAN mapping—Replaces one VLAN tag with another.

¡ Two-to-two VLAN mapping—Replaces the SVLAN ID, CVLAN ID, or both IDs for an incoming double-tagged frame.

· Policy-based VLAN manipulation—Uses a QoS policy to modify the CVLAN or SVLAN ID by using the remark customer-vlan-id or remark service-vlan-id action.

The devices in the service provider network learn MAC addresses of CVLANs into the MAC address table of the SVLAN.

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 QinQ, VLAN mapping, QoS nesting, and QoS priority and CVLAN marking.

Example: Configuring QinQ

Network configuration

As shown in Figure 1:

· The service provider assigns VLAN 1000 to Company A's VLANs 100 through 150.

· The service provider assigns VLAN 2000 to Company B's VLANs 120 through 200.

Configure QinQ on PE A and PE B to transmit traffic in VLANs 1000 and 2000 for Company A and Company B, respectively.

Restrictions and guidelines

When you configure QinQ, follow these restrictions and guidelines:

· You only need to configure QinQ on customer-side ports of PEs.

· The link type of the customer-side port can be access, hybrid, or trunk.

¡ If the link type is access, you must assign the port to the SVLAN.

¡ If the link type is trunk, you must assign the port to the SVLAN, and set the SVLAN ID as the PVID of the port.

¡ If the link type is hybrid, you must assign the port to the SVLAN as an untagged VLAN member, and set the SVLAN ID as the PVID of the port. The settings ensure that the port can forward traffic to the customer site with the SVLAN tag removed.

· For QinQ frames to travel across the service provider network, you must perform the following tasks:

¡ Set the MTU to a minimum of 1504 bytes for each port on the path of QinQ frames. This value is the sum of the default Ethernet interface MTU (1500 bytes) and the length (4 bytes) of a CVLAN tag. The CVLAN tag of QinQ frames is treated as part of the payload during transmission.

¡ Configure all the ports on the forwarding path to allow frames from VLANs 1000 and 2000 to pass through without removing the VLAN tag.

Example: Configuring one-to-two VLAN mapping

Network configuration

As shown in Figure 2:

· 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 3.

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

Figure 3 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.

Example: Configuring QoS policies for SVLAN tagging and 802.1p priority marking

Network configuration

As shown in Figure 4:

· 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 and require different transmission priorities for the three types of traffic.

Apply a QoS policy to each customer-side port on PE A and PE B to meet the following requirements:

· Separate the traffic by customer and traffic type.

· Assign different 802.1p priority values to the traffic flows.

Figure 4 Network diagram

Table 2 shows the VLAN and 802.1p priority assignment scheme. For each customer, the service provider assigns one SVLAN by traffic type. Figure 5 shows the expected traffic transmission pattern after the QoS policies are applied to customer-side ports.

Table 2 VLAN and traffic priority assignment

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

Figure 5 Expected traffic pattern in the service provider network

Analysis

For the customer-side ports to support multiple SVLANs and send traffic to the customer site with the SVLAN tag removed, you must perform the following tasks:

1. Configure the link type as hybrid on the customer-side ports.

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

To change the 802.1p priority for a class of traffic, use the remark dot1p action. By default, the 802.1p priority in the SVLAN tag added by a QinQ-enabled port depends on the priority trust mode on the port.

· If the 802.1p priority in frames is trusted, the device copies the 802.1p priority in the CVLAN tag to the SVLAN tag.

· If port priority is trusted, the port priority is used as the 802.1p priority in the SVLAN tag. For untagged incoming frames, the port encapsulates the port priority as the 802.1p priority in the SVLAN tag.

Restrictions and guidelines

When you configure an SVLAN tagging QoS policy, follow these restrictions and guidelines:

· Use the nest action for SVLAN tagging. You can configure only one nest action in the traffic behavior for a traffic class.

· You must apply the QoS policy to the inbound direction of customer-side ports.

· If an incoming frame does not match the QoS policy, the port adds the PVID tag to the frame as the SVLAN tag.

For QinQ frames to travel across the service provider network, follow these restrictions and guidelines:

· Set the MTU to a minimum of 1504 bytes for each port on the path of QinQ frames. This value is the sum of the default Ethernet interface MTU (1500 bytes) and the length (4 bytes) of a CVLAN tag. The CVLAN tag of QinQ frames is treated as part of the payload during transmission.

· Configure all the ports on the forwarding path to allow frames from VLANs 1001 through 1003 and VLANs 2001 through 2003 to pass through without removing the VLAN tag.

Example: Configuring two-to-two VLAN mapping

Network configuration

As shown in Figure 6:

· 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.

Example: Modifying the CVLAN ID through QoS marking

Network configuration

As shown in Figure 7:

· Company A uses CVLANs 10 and 20 to transmit voice traffic and data traffic, respectively.

· Company B uses CVLANs 30 and 40 to transmit voice traffic and data traffic, respectively.

· The service provider uses SVLANs 100 and 200 to transmit these two companies' voice and data traffic, respectively.

To provide Layer 2 connectivity for the voice and data traffic between the two companies, configure QoS CVLAN marking on PE A and PE B.

Figure 7 Network diagram

Analysis

To meet the network requirements, you must perform the following tasks:

· To add different SVLAN tags to voice and data traffic, use the nest action for SVLAN tagging on the customer-side ports of PE A and PE B.

· To provide Layer 2 connectivity for the traffic from different CVLANs, configure QoS CVLAN marking on the service provider-side ports of PE A and PE B.
