MPLS L2VPN commands
ac interface
Use ac interface to bind an AC to a cross-connect.
Use undo ac interface to remove the binding.
Syntax
ac interface interface-type interface-number [ service-instance instance-id ] [ access-mode { ethernet | vlan } ]
undo ac interface interface-type interface-number [ service-instance instance-id ]
Default
No AC is bound to a cross-connect

Parameters
interface-type interface-number: Specifies an interface.
service-instance instance-id: Specifies a service instance by its ID in the range of 1 to 4096.
access-mode: Specifies the access mode. By default, the access mode for a Layer 3 Ethernet subinterface, a VLAN interface, or a service instance is VLAN, and the access mode for other interfaces is Ethernet.
ethernet: Specifies the Ethernet access mode.
vlan: Specifies the VLAN access mode.
Usage guidelines
An AC can be a Layer 3 interface or a service instance on a Layer 2 interface.
After you bind a Layer 3 interface or a service instance on a Layer 2 interface to a cross-connect, the cross-connect forwards packets received from the Layer 3 interface or matching the service instance on the Layer 2 interface to the bound PW or another AC.
The access mode determines how the PE considers the VLAN tag in Ethernet frames received from the AC and how the PE forwards Ethernet frames to the AC.
· VLAN access mode—Ethernet frames received from the AC must carry a VLAN tag in the Ethernet header. The PE considers the VLAN tag as a P-tag assigned by the service provider. Ethernet frames sent to the AC must also carry the P-tag.
· Ethernet access mode—If Ethernet frames from the AC have a VLAN tag in the header, the PE considers it as a U-tag and ignores it. Ethernet frames sent to the AC do not carry the P-tag.
The service instance specified in this command must have match criteria configured by encapsulation.
Examples
# Configure service instance 200 on the Layer 2 interface GigabitEthernet 3/0/1 to match packets with an outer VLAN tag of 200, and bind the service instance to the cross-connect actopw in the cross-connect group vpn1.

Parameters
connection-name: Specifies the name of the cross-connect, a case-sensitive string of 1 to 20 characters, excluding hyphens.
Usage guidelines
A cross-connect is a point-to-point connection. You can execute ac interface and peer to connect an AC to a PW, so the PE can forward packets between the AC and the PW.
Examples
# Create cross-connect ac2pw for cross-connect group vpn1 and enter cross-connect view.
<Sysname> system-view
[Sysname] xconnect-group vpn1
[Sysname-xcg-vpn1] connection ac2pw

control-word enable
Use control-word enable to enable the control word function.
Use undo control-word enable to restore the default.
Syntax
control-word enable
undo control-word enable
Default
The control word function is disabled.
Views

Predefined user roles
network-admin
mdc-admin
Usage guidelines
The control word field is between the MPLS label stack and the Layer 2 data. It carries control information for the Layer 2 packet, such as the sequence number.
When the PW type is Ethernet or VLAN, the control word field is optional, and you can configure whether to carry the control word field in packets sent on the PW.
If the remote PE supports control word and requires the control word in packets, you must execute the control-word command on the local PE, so the a PW can be established between the PEs.
Examples
# Enable the control word function for the PW template pw100.
<Sysname> system-view
[Sysname] pw-class pw100
[Sysname-pw-pw100] control-word enable

encapsulation
Use encapsulation to configure match criteria for a service instance.
Use undo encapsulation to remove match criteria for a service instance.
Syntax
encapsulation s-vid vlan-id [ only-tagged ]
encapsulation { default | tagged | untagged }
undo encapsulation
Default
No match criteria are configured for a service instance.
Views
Service instance view
Predefined user roles
network-admin
mdc-admin
Parameters
s-vid vlan-id: Matches packets with a specified outer VLAN ID. The value range for the vlan-id argument is 1 to 4094.
only-tagged: Matches only tagged packets. If this keyword is not specified when the matching VLAN is the default VLAN, packets with the default VLAN ID or without any VLAN ID are all matched. If this keyword is specified when the matching VLAN is the default VLAN, only packets with the default VLAN ID are matched.
default: Specifies the default match criteria.
tagged: Matches tagged packets.
untagged: Matches untagged packets.
Usage guidelines
If service instances configured on an interface have identical match criteria, the service instances match packets with the specified VLAN IDs.
You can create multiple service instances on a Layer 2 Ethernet interface, but only one service instance can use the default match criteria (encapsulation default) to match packets that do not match any other service instance. If only one service instance using the default match criteria is configured on an interface, all packets received on the interface can match the service instance.
Removing the match criteria for a service instance also removes the cross-connect bound to the service instance.
Examples
# Configure service instance 1 on GigabitEthernet 5/0/1 to match packets that have an outer VLAN ID of 111 and an inner VLAN ID of 20 or from 30 to 40.
<Sysname> system-view

tunnel-policy tunnel-policy-name: Specifies a tunnel policy by its name, a case-sensitive string of 1 to 19 characters. If no tunnel policy is specified, the default tunnel policy is used.
Usage guidelines
To create a static PW, you must specify the incoming and outgoing labels. To enter the view of an existing static PW, you do not need to specify the incoming and outgoing labels.
The PW ID for a PW must be the same on the PEs at the ends of the PW.
The LSR ID of the peer PE and the PW ID uniquely identify a PW, and must not be both the same as those of any VPLS PW or cross-connect PW.
Examples
# Configure an LDP PW destined to 4.4.4.4 for the cross-connect pw2pw in the cross-connect group vpn1 and enter PW view. The PW ID is 200.
<Sysname> system-view
[Sysname] xconnect-group vpn1
[Sysname-xcg-vpn1] connection pw2pw
[Sysname-xcg-vpn1-pw2pw] peer 4.4.4.4 pw-id 200
[Sysname-xcg-vpn1-pw2pw-4.4.4.4-200]

pw-class
Use pw-class to create a PW template and enter PW template view.
Use undo pw-class to delete a PW template.
Syntax
pw-class class-name
undo pw-class class-name
Default
No PW template is created.

Parameters
class-name: Specifies the name of the PW template, a case-sensitive string of 1 to 19 characters.
Usage guidelines
In PW template view, you can configure PW attributes such as the PW type and whether to enable control word. PWs with the same attributes can use the same PW template to simplify configuration.
Examples
# Create a PW template named pw100 and enter PW view.
<Sysname> system-view
[Sysname] pw-class pw100
[Sysname-pw-pw100]

pw-type
Use pw-type to specify a PW type for a PW template.
Use undo pw-type to restore the default.
Syntax
pw-type { ethernet | vlan }
undo pw-type
Default
The PW type is VLAN.
Views

Parameters
ethernet: Specifies the PW type as Ethernet.
vlan: Specifies the PW type as VLAN.
Usage guidelines
When the PW type is Ethernet, the PE encapsulates packets forwarded between the AC and PW as follows:
· Traffic from the AC to the PW cannot carry the P-Tag assigned by the service provider. If traffic from the AC has the P-Tag, the PE removes the P-Tag, adds the PW label and public tunnel encapsulation, and forwards the traffic through the PW. If traffic from the AC does not have the P-Tag, the PE adds the PW label and public tunnel encapsulation and forwards the traffic through the PW.
· For traffic received from the PW, if the AC access mode (configured by as interface) is VLAN, the PE adds the P-Tag and forwards the traffic through the AC. If the AC access mode is Ethernet, the PE directly forwards the traffic through the AC. The PE cannot modify or delete the P-Tag for the traffic from the PW.
When the PW type is VLAN, the PE encapsulates packets forwarded between the AC and PW as follows:
· Traffic from the AC to the PW must carry the P-Tag. If traffic from the AC has the P-Tag, the PE keeps the P-Tag when the peer PE does not require the ingress to modify the P-Tag or changes the P-Tag to the expected value (which can be zero) when the peer PE requires the ingress to modify the P-Tag, then adds the PW label and public tunnel encapsulation, and forwards the traffic through the PW. If traffic from the AC does not have the P-Tag, the PE adds a P-Tag of 0 when the peer PE does not require the ingress to modify the P-Tag or adds the expected P-Tag (which can be zero) when the peer PE requires the ingress to modify the P-Tag, then adds the PW label and public tunnel encapsulation, and forwards the traffic through the PW.
· For traffic received from the PW, if the AC access mode (configured by as interface) is VLAN, the PE modifies or keeps the P-Tag and forwards the traffic through the AC. If the AC access mode is Ethernet, the PE removes the P-Tag and forwards the traffic through the AC.
This command takes effect only when the AC type is Ethernet.
