Parameters

**Table 1** Descriptions of the parameters for Ethernet virtual interface Layer 3 Attributes
Field	Value	Description
Port	For example: 1	Display the port.
Port Type	VLAN Sub Interface, EoA Virtual Interface	Display the port type.
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.
Specify IP Address	Manually, Unspecified	Selects the means of setting the IP address for the port.
IP Address	For example: 10.70.70.11	Set the IP address of the port. When Port Mode in Basic Attributes is set to Layer 3, you can set this parameter.
IP Mask	For example: 255.255.255.0	Set the IP address mask of the port. When Port Mode in Basic Attributes is set to Layer 3, 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.
