The encapsulation eth out-interface command is used to configure the Layer 2 forwarding interface to support the SFF to the SF.
The undo encapsulation eth out-interface command is used to disable the configuration of Layer 2 forwarding from SFF to SF.
By default, Layer 2 forwarding with SFF to SF is not configured.

undo encapsulation eth out-interface { outInterfaceName | outInterfaceType outInterfaceNum } [ out-vlan out-vlan-id [ ce-vid out-cevid ] ] in-interface { inInterfaceName | inInterfaceType inInterfaceNum } [ in-vlan in-vlan-id [ ce-vid in-cevid ] ] [ dest-mac destMac ]
| Parameter | Description | Value |
|---|---|---|
| outInterfaceName |
Specifies the type of an outbound interface. |
- |
| outInterfaceType |
Specifies the name of an outbound interface. |
- |
| outInterfaceNum |
Specifies the number of an outbound interface. |
- |
| out-vlan out-vlan-id |
Specifies the outer VLAN ID of an outbound interface. |
The value is an integer ranging from 1 to 4094. |
| ce-vid out-cevid |
Specifies the inner VLAN ID of an outbound interface. |
The value is an integer ranging from 1 to 4094. |
| ce-vid in-cevid |
Specifies the inner VLAN ID of an inbound interface. |
The value is an integer ranging from 1 to 4094. |
| in-interface inInterfaceName |
Specifies the name of an inbound interface. |
- |
| inInterfaceType |
Specifies the type of an inbound interface. |
- |
| inInterfaceNum |
Specifies the number of an inbound interface. |
- |
| in-vlan in-vlan-id |
Specifies the outer VLAN ID of aninbound interface. |
The value is an integer ranging from 1 to 4094. |
| dest-mac destMac |
Specifies a MAC address. |
The value is a hexadecimal number in the format of H-H-H. H is a 4-bit hexadecimal number, such as 00e0 or fc01. If an H contains fewer than 4 digits, the left-most digits are padded with zeros. For example, e0 is equal to 00e0. A MAC address cannot be set to all Fs, all 0s, or any multicast MAC address. |
Usage Scenario
Supports Layer 2 forwarding from the SFF to the SF. Only one type of forwarding can be configured. out-interface and in-interface can be set to the same sub-interface or different sub-interfaces.
Destination MAC address to be encapsulated in the packets forwarded to the SF. The MAC address of the in-interface is used by default. In the scenario where SF is dual-homed to SFF, SFF1 does not know the MAC address of SFF2 in-interface. Therefore, you need to run the dest-mac command to configure the static configuration.Precautions
To ensure correct forwarding,set the interface type to EVC Layer 2 sub-interface. An interface must be exclusively used by a service chain. If a service chain is configured on an interface, the interface cannot be configured to other services. Otherwise, forwarding problems may occur.
