encapsulation eth out-interface

Format

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 ]

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 ]

Parameters

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 Guidelines

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.

Example

# Configure the Layer 2 forwarding function from SFF to SF. The outbound interface is GigabitEthernet 0/1/0.1, the inbound interface is GigabitEthernet 0/1/8.2, the outbound VLAN ID is 2, the inbound VLAN ID is 4, the outbound CE VLAN ID is 3, the inbound CE VLAN ID is 5, and the destination MAC address is abc-de-89.
