During the service configuration or test on an Ethernet board,
the Ethernet board attributes must be configured.
Context
Follow the process given below to configure an Ethernet board:
Setting Basic Attributes of Ethernet Interfaces
Before you configure the Layer 2 and Layer 3 attributes of an Ethernet interface, configure the basic attributes of the corresponding Ethernet interface. The basic attributes of an Ethernet interface define the physical-layer information, such as the port mode, encapsulation type, and maximum frame length.
Setting Layer 2 Attributes of an Ethernet Interface
After Layer 2 attributes of an Ethernet interface are set, the interface can be used for connecting to the client-side equipment at the edge of an SDH network or for forwarding Ethernet packets within the SDH network. The Layer 2 attributes of an Ethernet interface define the related information of the data link layer.
Setting Layer 3 Attributes of an Ethernet Interface
When an Ethernet interface is used to carry a tunnel, you need to configure the Layer 3 attributes of the Ethernet interface. The Layer 3 attributes of an Ethernet interface define the related attributes of the network layer.
Configuring Flow Control
If congestion occurs on the link when the flow control function is enabled, the Ethernet interface sends a PAUSE frame to the opposite end, and then the opposite end stops transmitting Ethernet packets. As a result, congestion is avoided.
