vlan-type dot1q (sub-interface view)

Function

The vlan-type dot1q command configures a matching policy on a common Dot1q sub-interface. After this matching policy is configured, VLAN services access the corresponding L2VPN or L3VPN based on the VLAN ID+802.1p value/DSCP value/EthType.

The undo vlan-type dot1q 8021p command deletes the matching policy on the common dot1q sub-interface.

By default, no matching policy is configured on the common Dot1q sub-interface.

Format

vlan-type dot1q vlanid { 8021p { 8021p-value1 [ to 8021p-value2 ] } &<1-8> | dscp { dscp-value1 [ to dscp-value2 ] } &<1-10> | eth-type PPPoE | default }

undo vlan-type dot1q vlanid { 8021p { 8021p-value1 [ to 8021p-value2 ] } &<1-8> | dscp { dscp-value1 [ to dscp-value2 ] } &<1-10> | eth-type PPPoE | default }

Parameters

Parameter	Description	Value
vlanid	Specifies the VLAN ID.	The value is an integer ranging from 1 to 4094.
8021p	Specifies the priority of a VLAN frame.	-
8021p-value1	Specifies the minimum priority of a VLAN frame.	The value ranges from 0 to 7. The greater the value, the higher the priority.
8021p-value2	Specifies the maximum priority of a VLAN frame.	The value ranges from 0 to 7. The greater the value, the higher the priority.
dscp	Specifies the DSCP (DiffServ Code Point) value of user packets.	-
dscp-value1	Specifies the minimum DSCP (DiffServ Code Point) value of user packets.	The value is an integer ranging from 0 to 63.
dscp-value2	Specifies the maximum DSCP (DiffServ Code Point) value of user packets.	The value is an integer ranging from 0 to 63.
eth-type	The Ethernet encapsulation type.	-
PPPoE	The Ethernet encapsulation type is PPPoE.	-
default	Specifies a sub-interface to match VLAN services that are not matched by other sub-interfaces.	-

Usage Guidelines

Usage Scenario

On a Layer 2 network, users and services are identified using a single or double tags. In some scenarios, the access device uses a single tag to identify multiple service or does not support QinQ. In this case, the access device may map service access information to packets' 802.1p/DSCP field. Therefore, it is required that the edge device of the Layer 2 network use the 802.1p/DSCP value to identify access users, differentiate the accesses to different VPNs, and set up different QoS scheduling policies to classify traffic. After a matching policy is configured using the vlan-type dot1q 8021p command, VLAN services access the L2VPNs or L3VPNs based on the VLAN ID+802.1p value/DSCP value/EtherType.

Different combinations of parameters in the vlan-type dot1q 8021p command are applied to the following scenarios:

L2VPN or L3VPN access based on the VLAN ID+802.1p value
L2VPN or L3VPN access based on the VLAN ID+DSCP value
L2VPN access based on the VLAN ID+EthType

Precautions

If the same VLAN ID is encapsulated on different sub-interfaces of an interface, the sub-interfaces must use matching policies of the same type (802.1p value/DSCP value/EthType).

One VLAN ID can be encapsulated on a maximum of eight sub-interfaces.

If you specify default in the command, all services of any VLAN within the VLAN range, except that those matching the matching policy are processed by the corresponding sub-interface, are processed by the default sub-interface.

If you specify the VLAN ID+802.1p value/DSCP value/EthType in the undo vlan-type dot1q 8021p command, the command deletes only the specified matching policy. The undo vlan-type dot1q vlanid command deletes all matching policies within the VLAN range on the sub-interface.

Among all types of VE sub-interfaces, the vlan-type dot1q 8021p command and undo form are supported only by L3 access VE sub-interfaces. To configure an L3 access VE sub-interface, run the ve-group ve-group-id command.

In the L3 access VE sub-interface view, the vlan-type dot1q 8021p command and its undo form cannot coexist with IPv6 and multicast services.

The EthType matching policy cannot be configured in the VE or global VE sub-interface view.
