Port Attributes

In this interface, attributes of the port used by the Ethernet service are displayed.

Navigation Path

Creation and query of the E-Line, E-LAN or E-AGGR service requires information in this interface. The navigation paths for the three services are as follows:

For RTN NEs: In the NE Explorer, click the NE and choose Configuration > Ethernet Service Management > E-Line Service. Then, click the Port Attributes tab.
For RTN NEs: In the NE Explorer, click the NE and choose Configuration > Ethernet Service Management > E-LAN Service. Then, click the Port Attributes tab.
For RTN NEs: In the NE Explorer, click the NE and choose Configuration > Ethernet Service Management > E-AGGR Service. Then, click the Port Attributes tab.

Parameters

**Table 1** Descriptions of the parameters for Port Attributes
Field	Value	Description
Port	Example: Slot-Board Name-Port (Port No.)	Display the name of the port on the NE. Slot number - Board name - Port information
Port Enable	Enable, Disable	Display the enable status of the port.
Port Mode	Layer 2, Layer 3	Select the working mode of the 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.
Encapsulation Type	Null, 802.1Q, QinQ	Display the encapsulation type of the Ethernet port. 802.1Q indicates that a four-byte 802.1Q tag is inserted between the source MAC address section and the protocol type section. QinQ indicates that the 802.1Q is embedded with the 802.1Q.
Working Mode	Auto-Negotiation, 10M Half-Duplex, 10M Full-Duplex, 100M Half-Duplex, 100M Full-Duplex, 1000M Half-Duplex, 1000M Full-Duplex, 10G Full-Duplex LAN, 10G Full-Duplex WAN	Indicates the working mode of the Ethernet port. The auto-negotiation mode is recommended, because it can automatically find out the best working mode to combine a port and its interconnected port and thus is convenient for maintenance. Be careful to configure the same working mode for the port and its interconnected port. Otherwise, service will fail.
Tag	Tag Aware, Access, Hybrid	The tag indicates which packets can be processed. Tag Aware: The port transparently transmits the data packet with a VLAN ID (tag). If a data packet does not have a VLAN ID (untag), the port discards this data packet. In this case, the Default VLAN ID and VLAN Priority are meaningless. Access: The port adds the default VLAN ID to the data packet without any VLAN ID (untag). If the data packet has a VLAN ID (tag), the port discards this data packet. Hybrid: The port adds the default VLAN ID to the data packet without any VLAN ID (untag). If the data packet has a VLAN ID (tag), the port transparently transmits the data packet.
Specify IP Address	Unspecified, Manually	Indicates the port IP address setting mode. Unspecified: the IP address can be dynamically allocated. Manually: the IP address of the port can be manually configured. NOTE: This parameter is available when Port Mode is Layer 3.
IP Address	For example: 192.168.0.1	Sets the IP address for the port. NOTE: When Specify IP Address is set to Manually, you can set this parameter. CAUTION: Modifying the IP address can cause the equipment to re-establish the link. As a result, the services are interrupted.
