· Flexibility—A VLAN can be logically divided on a workgroup basis. Hosts in the same workgroup can be assigned to the same VLAN, regardless of their physical locations.

VLAN frame encapsulation

To identify Ethernet frames from different VLANs, IEEE 802.1Q inserts a four-byte VLAN tag between the destination and source MAC address (DA&SA) field and the Type field.

Figure 1 VLAN tag placement and format

A VLAN tag includes the following fields:

· TPID—16-bit tag protocol identifier that indicates whether a frame is VLAN-tagged. By default, the hexadecimal TPID value 8100 identifies a VLAN-tagged frame. A device vendor can set the TPID to a different value. For compatibility with a neighbor device, set the TPID value on the device to be the same as the neighbor device.

· Priority—3-bit long, identifies the 802.1p priority of the frame. For more information, see ACL and QoS Configuration Guide.

· CFI—1-bit long canonical format indicator that indicates whether the MAC addresses are encapsulated in the standard format when packets are transmitted across different media. Available values include:

¡ 0 (default)—The MAC addresses are encapsulated in the standard format.

¡ 1—The MAC addresses are encapsulated in a non-standard format.

This field is always set to 0 for Ethernet.

· VLAN ID—12-bit long, identifies the VLAN to which the frame belongs. The VLAN ID range is 0 to 4095. VLAN IDs 0 and 4095 are reserved, and VLAN IDs 1 to 4094 are user configurable.

The way a network device handles an incoming frame depends on whether the frame has a VLAN tag and the value of the VLAN tag (if any).

Ethernet supports encapsulation formats Ethernet II, 802.3/802.2 LLC, 802.3/802.2 SNAP, and 802.3 raw. The Ethernet II encapsulation format is used here. For information about the VLAN tag fields in other frame encapsulation formats, see related protocols and standards.

For a frame that has multiple VLAN tags, the device handles it according to its outermost VLAN tag and transmits its inner VLAN tags as the payload.

Port-based VLANs

Port-based VLANs group VLAN members by port. A port forwards packets from a VLAN only after it is assigned to the VLAN.

Port link type

You can set the link type of a port to access, trunk, or hybrid. The port link type determines whether the port can be assigned to multiple VLANs. The link types use the following VLAN tag handling methods:

· Access—An access port can forward packets only from one VLAN and send these packets untagged. An access port is typically used in the following conditions:

¡ Connecting to a terminal device that does not support VLAN packets.

¡ In scenarios that do not distinguish VLANs.

· Trunk—A trunk port can forward packets from multiple VLANs. Except packets from the port VLAN ID (PVID), packets sent out of a trunk port are VLAN-tagged. Ports connecting network devices are typically configured as trunk ports.

· Hybrid—A hybrid port can forward packets from multiple VLANs. The tagging status of the packets forwarded by a hybrid port depends on the port configuration.

PVID

The PVID identifies the default VLAN of a port. Untagged packets received on a port are considered as the packets from the port PVID.

An access port can join only one VLAN. The VLAN to which the access port belongs is the PVID of the port. A trunk or hybrid port supports multiple VLANs and the PVID configuration.

How ports of different link types handle frames

Actions	Access	Trunk	Hybrid
In the inbound direction for an untagged frame	Tags the frame with the PVID tag.	· If the PVID is permitted on the port, tags the frame with the PVID tag. · If not, drops the frame.
In the inbound direction for a tagged frame	· Receives the frame if its VLAN ID is the same as the PVID. · Drops the frame if its VLAN ID is different from the PVID.	· Receives the frame if its VLAN is permitted on the port. · Drops the frame if its VLAN is not permitted on the port.
In the outbound direction	Removes the VLAN tag and sends the frame.	· Removes the tag and sends the frame if the frame carries the PVID tag and the port belongs to the PVID. · Sends the frame without removing the tag if its VLAN is carried on the port but is different from the PVID.		Sends the frame if its VLAN is permitted on the port. The tagging status of the frame depends on the port hybrid vlan command configuration.

Layer 3 communication between VLANs

Hosts of different VLANs use VLAN interfaces to communicate at Layer 3. VLAN interfaces are virtual interfaces that do not exist as physical entities on devices. For each VLAN, you can create one VLAN interface and assign an IP address to it. The VLAN interface acts as the gateway of the VLAN to forward packets at Layer 3. When the IP addresses of multiple VLAN interfaces are on different subnets, you must configure IP routing protocols to enable Layer 3 communication between these IP addresses. Then, the devices can forward packets at Layer 3 across subnets between different VLANs. For more information about IP routing protocols, see Layer 3—IP Routing Configuration Guide.

Protocols and standards

IEEE 802.1Q, IEEE Standard for Local and Metropolitan Area Networks: Virtual Bridged Local Area Networks

Restrictions and guidelines: VLAN configuration

· As the system default VLAN, VLAN 1 cannot be created or deleted.

· Before you delete a dynamic VLAN or a VLAN locked by an application, you must first remove the configuration from the VLAN.

Creating VLANs

1. Enter system view.

system-view

2. Create one or multiple VLANs.

¡ Create a VLAN and enter its view.

vlan vlan-id

¡ Create multiple VLANs and enter VLAN view.

Create VLANs.

vlan { vlan-id1 to vlan-id2 | all }

Enter VLAN view.

vlan vlan-id

By default, only the system default VLAN (VLAN 1) exists.

3. (Optional.) Set a name for the VLAN.

name text

By default, the name of a VLAN is VLAN vlan-id. The vlan-id argument specifies the VLAN ID in a four-digit format. If the VLAN ID has fewer than four digits, leading zeros are added. For example, the name of VLAN 100 is VLAN 0100.

4. (Optional.) Configure the description for the VLAN.

description text

By default, the description of a VLAN is VLAN vlan-id. The vlan-id argument specifies the VLAN ID in a four-digit format. If the VLAN ID has fewer than four digits, leading zeros are added. For example, the default description of VLAN 100 is VLAN 0100.

Configuring port-based VLANs

Restrictions and guidelines for port-based VLANs

· When you use the undo vlan command to delete the PVID of a port, either of the following events occurs depending on the port link type:

¡ For an access port, the PVID of the port changes to VLAN 1.

¡ For a hybrid or trunk port, the PVID setting of the port does not change.

You can use a nonexistent VLAN as the PVID for a hybrid or trunk port, but not for an access port.

· As a best practice, set the same PVID for a local port and its peer.

· To prevent a port from dropping untagged packets or PVID-tagged packets, assign the port to its PVID.

Configuring super VLANs

About super VLANs

Hosts in a VLAN typically use IP addresses in the same subnet. For Layer 3 interoperability with other VLANs, you can create a VLAN interface for the VLAN and assign an IP address to it. This requires a large number of IP addresses.

The super VLAN feature was introduced to save IP addresses. A super VLAN is associated with multiple sub-VLANs. These sub-VLANs use the VLAN interface of the super VLAN (also known as a super VLAN interface) as the gateway for Layer 3 communication.

You can create a VLAN interface for a super VLAN and assign an IP address to it. However, you cannot create a VLAN interface for a sub-VLAN. You can assign a physical port to a sub-VLAN, but you cannot assign a physical port to a super VLAN. Sub-VLANs are isolated at Layer 2.

To enable Layer 3 communication between sub-VLANs, perform the following tasks:

1. Create a super VLAN and the VLAN interface for the super VLAN.

2. Enable local proxy ARP or ND on the super VLAN interface as follows:

¡ In an IPv4 network, enable local proxy ARP on the super VLAN interface. The super VLAN can then process ARP requests and replies sent from the sub-VLANs.

¡ In an IPv6 network, enable local proxy ND on the super VLAN interface. The super VLAN can then process the NS and NA messages sent from the sub-VLANs.

Restrictions and guidelines: Super VLAN configuration

· Do not configure a VLAN as both a super VLAN and a sub-VLAN.

· Layer 2 multicast configuration for super VLANs does not take effect because they do not have physical ports.
