Layer 3 Attributes

In this interface, you can query and set the Layer 3 attributes of the Ethernet interface.

Navigation Path

For RTN NEs, in the NE Explorer, select an NE and choose Configuration > Interface Management > Ethernet Interface from the Function Tree. Click the Layer 3 Attributes tab.

In the NE Explorer, select a board and choose Configuration > Interface Management > Ethernet Interface from the Function Tree. Click the Layer 3 Attributes tab.

Parameters

**Table 1** Descriptions of the parameters for Ethernet interface Layer 3 attributes
Field	Value	Description
Port	For example: Slot-Board Name-Port (Port No.)	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.
Max Reserved Bandwidth (kbit/s)	For example: 102400	Sets the maximum bandwidth used by the tunnel. The maximum reserved bandwidth should not exceed the physical bandwidth of the bearer port.
Available Bandwidth (kbit/s)	For example: 100000	Displays the available bandwidth of the port. The Available Bandwidth value is obtained from equipment and refreshed automatically when the Max Reserved Bandwidth value of the port is modified or the tunnel traversing the port is adjusted.
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. This parameter can be set only when Specify IP is set to Manually.
IP Mask	For example: 255.255.255.0	Sets the subnet mask of the port. This parameter can be set only when Specify IP is set to Manually.
Board for Borrowed IP Address	-	The parameter is not supported.
Port for Borrowed IP Address	-	The parameter is not supported.
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.
