Layer 3 Attributes

The Layer 3 attributes of a microwave interface define the related attributes of the network layer. In this interface, you can query and set the Layer 3 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 Layer 3 Attributes tab.
In the NE Explorer, select a board and choose Configuration > Interface Management > Microwave Interface from the Function Tree. Click the Layer 3 Attributes tab.

Parameters

**Table 1** Descriptions of the parameters for microwave interface Layer 3 attributes
Field	Value	Description
Port	slot number-board name-port number(port name)	Displays the port name.
Enable Tunnel	Enabled, Disabled	After the Tunnel is enabled, the port can identify and process the MPLS label, and thus supports the dynamic signaling and route. When Port Mode in Basic Attributes is set to Layer 3, you can set this parameter.
Max Reserved Bandwidth (kbit/s)	0 to 4294967295	Sets the maximum bandwidth used by the tunnel. The maximum reserved bandwidth should not exceed the physical bandwidth of the bearer port.
TE Measurement	0 to 16777215	Sets the TE measurement. You can intervene in the route selection by adjusting the TE measurement of the link. The smaller the value of the TE measurement, the higher the priority of the link. Thus, the traffic congestion of the shortest path that occurs in the traditional route selection can be avoided.
Admin Group	0 to 4294967295	Sets the admin group. The admin group can specify the link attributes. After the affinity attributes of a dynamic tunnel is configured, when the dynamic tunnel selects links, the dynamic tunnel compares its affinity attributes with the admin attributes of links and determines which links to be avoided.
Specify IP Address	Manually, Unspecified	Selects the means of setting the IP address for the port.
IP Address	For example: 192.168.0.1	Sets the IP address for the port. When Specify IP is set to Manually, you can set this parameter. When modifying the IP address of the interface, make sure that the IP address of this interface and the IP addresses of other interfaces configured with services are not in the same subnet. CAUTION: Modifying the IP address can cause the equipment to re-establish the link. As a result, the services are interrupted.
IP Mask	For example: 255.255.255.0	Sets the subnet mask of the port. When Specify IP is set to Manually, you can set this parameter.
MTU (bytes)	46 to 9600	Indicate the maximum transport unit (MTU). When receiving packets of a length more than the MTU, the port divides the packets into segments and then transport these segments. If the packets contain a flag indicating that packet division is not allowed, the port discards the packet.
