Ethernet Interface

When an NE transmits Ethernet services to a microwave transmission network through an internal port (namely, VCTRUNK) of an Ethernet service board, you need to set the attributes of the internal port so that the Ethernet service board of the local NE can work with the Ethernet service board of the NE at the opposite end to realize the transmission of the Ethernet services on the microwave transmission network. In this user interface, you can manage Ethernet interface.

Navigation Path

In the NE Explorer, click the Ethernet board and select Configuration > Ethernet Interface Management > Ethernet Interface from the Function Tree.

Guideline

To ensure the availability of an end-to-end Ethernet service, make sure that the port attributes of the Ethernet boards at the two ends of the services are the same.

Adhere to the following principles when planning VCTRUNKs:

The capacity of VCTRUNKs should be determined by the actual bandwidth of the service needs.
Bind only the paths in a VC-4 if possible. If the paths of several VC-4s need to be bound, the VC-4s that have the same transmission path take priority.
As each VC-4 of the Ethernet board can bind only VC-3 or VC-12, give priority to the VC-4s whose paths are already bound with the VC-12 or VC-3.
As the VC-4-1 of the EFT4 board and EMS6 board can bind only VC-3 paths whereas the VC-4-2 can bind both VC-12 and VC-3 paths, give priority to the paths in the VC-4-1 if VC-3 paths are to be bound.

**Table 1** Methods used by ports to process data frames
Direction	Type of Data Frame	Processing Method
Direction	Type of Data Frame	Tag aware	Access	Hybrid
Ingress port	Tagged frame	Receives the frame.	Discards the frame.	Receives the frame.
Ingress port	Untagged frame	Discards the frame.	The port receives the frame after adding to the frame the VLAN tag that contains Default VLAN ID and VLAN Priority.	The port receives the frame after adding to the frame the VLAN tag that contains Default VLAN ID and VLAN Priority.
Egress port	Tagged frame	Transmits the frame.	The port strips the VLAN tag from the frame and then transmits the frame.	If the VLAN ID in the frame is Default VLAN ID, the port strips the VLAN tag from the frame and then transmits the frame. If the VLAN ID in the frame is not Default VLAN ID, the port directly transmits the frame.

Basic Attributes (External Port)
In this user interface, you can query and set basic attributes of a MAC port.
Basic Attributes (Internal Port)
When an NE transmits Ethernet services to a microwave transmission network through an internal port (namely, VCTRUNK) of an Ethernet service board, you need to set the attributes of the internal port so that the Ethernet service board of the local NE can work with the Ethernet service board of the NE at the opposite end to realize the transmission of the Ethernet services on the microwave transmission network. In this user interface, you can query or set basic attributes of an internal port, including port and QinQ type area.
Flow Control (External Port)
In this user interface, you can enable and disable the auto-negotiation or non-auto-negotiation flow control mode for an external port.
TAG Attributes
In this user interface, you can query and set the TAG attribute for a PORT port or a VCTRUNK port.
Network Attributes
In this user interface, you can set port attributes.
Bound Path
In this user interface, you can query or configure path binding.
Advanced Attributes (External Port)
In this user interface, you can set and query advanced attributes for an external port.
Advanced Attributes (Internal Port)
In this user interface, you can set and query advanced attributes for an internal port.
Encapsulation/Mapping
In this user interface, you can set and query the encapsulation and mapping status of Ethernet data packets.
LCAS
The LCAS is applied on the basis of virtual concatenation and can improve the performance of virtual concatenation. The LCAS can dynamically adjust the number of virtual containers for mapping required services to meet the bandwidth requirements of the application. As a result, the bandwidth utilization is improved. In this user interface, you can enable or disable the link capacity adjustment scheme (LCAS) function.
