Basic Attributes

Before you configure the Layer 2 and Layer 3 attributes of a microwave interface, you need to configure the basic attributes of the corresponding microwave interface. The basic attributes of a microwave interface define the physical-layer information, such as the port mode, encapsulation type, and maximum frame length. In this interface, you can query and set the Basic Attributes of the microwave interface.

Navigation Path

In the NE Explorer, select an NE and choose Configuration > Interface Management > Microwave Interface from the function tree. Click the Basic Attributes tab.
In the NE Explorer, select a board and choose Configuration > Interface Management > Microwave Interface from the Function Tree. Click the Basic Attributes tab.

Parameters

**Table 1** Descriptions of the parameters for microwave interface Basic Attributes
Field	Value	Description
Port	slot number-board name-port number(port name)	Display the port name.
Name	For example: Port1	Enter the self-defined port name.
Ethernet Packet Header Compression	Disabled, Enabled	Enables or disables the function of compressing Ethernet packet headers.
Port Mode	Layer 2, Layer 3, Layer Mix	Select the working mode of the Ethernet port. Layer 2: The port can access the user-side equipment or carry Ethernet services that are based on the ports and use the port exclusively. Layer 3: The port can carry tunnels. Layer Mix: The port can carry mix service of layer 2 and layer 3.
Encapsulation Type	Null, 802.1Q, QinQ	Select the means of processing the accessed packets. Null: The port transparently transmits the accessed packets. 802.1Q: The port identifies the 802.1Q standard packets. QinQ: The port identifies the QinQ standard packets. The Encapsulation Type is always 802.1Q when you set Port Mode to Layer 3.
MTU (bytes)	1620 to 9600	Set the maximum transport unit (MTU).In the case an NNI interface, MTU(bytes), which indicates the maximum data packet length, must be set to a value larger than 960. A DCN packet contains a maximum of 960 bytes. If MTU(bytes) is smaller than 960, the DCN packets in the receive direction may be lost.
Running Status	Up, Down	Indicates the running status of the port. Up indicates the port has no alarm and can be used normally.
Traffic Policing Status	Enabled, Disabled	Sets the traffic policing status of the port.
Traffic Policing Period (min)	1 to 30	Sets the traffic policing period.
