Configuring External Ports

The attributes of Ethernet interfaces need to be configured when Ethernet boards are configured with services or used for tests. You can configure the external ports for an Ethernet board.

Prerequisites

The Ethernet board must be created.

Background Information

NOTICE:

To ensure the availability of an end-to-end Ethernet service, make sure that the port attributes of the Ethernet boards at the two ends of the services are the same.

Procedure

  1. In the NE Explorer, select the appropriate Ethernet board and then select Configuration > Ethernet Interface Management > Ethernet Interface from the Function Tree. Select the External Port option button.
  2. Click the Basic Attributes tab and set the basic attributes of the external port.



    NOTE:
    • Working mode: The default value is Auto-Negotiation (The two connected ports make negotiations through the pulse of each port to ensure that the two ports are working in the working mode at the supported highest level). Check the working mode of the receive port and the transmit port and ensure the modes are the same.
    • MAC loopback and PHY loopback: They are used for locating faults and are service-affecting. The two are mutually exclusive. When the value of MAC loopback is set to Inloop, the value of PHY loopback is set to Non-Loopback automatically. The same applies to the reverse case.

  3. Click Apply.
  4. Click Flow Control tab, set the Non-Autonegotiation Flow Control Mode and Autonegotiation Flow Control Mode of the external port.



    NOTE:
    • Autonegotiation flow control mode: Select this mode when the working mode of the port is Auto-Negotiation. Enable Dissymmetric Flow Control means the port only transmits and does not receive flow control frames. Enable Symmetric Flow Control means that the port is able to transmit and receive only PAUSE frames. Enable Symmetric/Dissymmetric Flow Control means that the symmetric or dissymmetric flow control mode is selected according to the auto-negotiation.
    • Non-Autonegotiation flow control mode: Select this mode when the working mode of the port is not Auto-Negotiation. Enable Symmetric Flow Control means that the port is able to transmit and receive PAUSE frames. Send Only means that the port is able to transmit PAUSE frames only. Receive Only means the port is able to receive PAUSE frames only.

  5. Click Apply.
  6. Click the TAG Attributes tab and set the TAG of the port. Click Apply.



  7. Click Network Attributes tab, set the port attributes of the external port.



    NOTE:
    • In the case of UNI, the port processes the TAG attribute of 802.1Q and the port is with the Tag Aware/Access/Hybrid attribute.
    • In the case of C-Aware, the port does not process the TAG attribute of 802.1Q. It determines that the data packet carries C-VLAN tag and processes the data packet based on the C-VLAN tag.
    • In the case of S-Aware, the port does not process the TAG attribute of 802.1Q. It determines that the data packet carries S-VLAN tag and processes the data packet based on the S-VLAN tag.

  8. Click Apply.
  9. Click the Advanced Attributes tab and set the port attribute.



    NOTE:
    • The Advanced Attributes tab is available for the 11LEX4, 11LEM24, TBE boards only.
    • Broadcast packet suppression is based on the proportion between the broadcast packet and all packets. The value ranges from 10% to 100%, with an increment of 10%.

  10. Click Apply.
