Basic Attributes
Before configuring Ethernet services in packet mode, you need to set the basic attributes of Ethernet ports.
Field |
Value Range |
Description |
|---|---|---|
Port |
Example: 3-EM6F-1(PORT-1) | Displays the port name. |
Name |
Example: Port 1 | Enters the port name specified by the user. |
| Enable Port | Enabled, Disabled Default value: Enabled |
The Enable Port parameter sets whether the Ethernet port is usable. Impact on the System:When services are available on the Ethernet port, setting this port to disabled interrupts the services. Value description:
When a port is used for transmitting services, enable this port first. |
Port Mode |
Layer 2, Layer 3 Default value: Layer 2 |
Selects the working mode of the Ethernet port.
|
| Encapsulation Type | Null, 802.1Q, QinQ Default value: 802.1Q |
The Encapsulation Type parameter sets the link layer encapsulation type of the port, and specifies the link layer encapsulation type that can be identified by this port. Value description:
Currently, the encapsulation type of the Ethernet port can be set. In addition, the encapsulation type can be switched only when the port does not carry services. In the Layer 2 mode, the encapsulation type of the Ethernet port can be Null, 802.1Q, and QinQ. In the Layer 3 mode, the encapsulation type of the Ethernet port, which is fixed to 802.1Q, cannot be set. |
| Working Mode | 10M Half-Duplex, 10M Full-Duplex, Auto-Negotiation, 100M Half-Duplex, 100M Full-Duplex, 1000M Full-Duplex, 10G Full-Duplex LAN, 10G Full-Duplex WAN Default value: Auto-Negotiation NOTE:
|
Set the Working Mode parameter to set the working mode of the Ethernet port on the board. The Working Mode parameter indicates the maximum transmission rate and communication mode of a port. Impact on the System:If the working modes of interconnected Ethernet ports are inconsistent, the services are not available or have a severe packet loss problem. Value description:
The Auto-Negotiation working mode is recommended. If the communication fails and the working mode of the port is set to Auto-Negotiation, you need specify the working mode of the port according to the working mode of the interconnected port. If the working mode of the port is set to any other mode instead of Auto-Negotiation, the working mode of the interconnected port should be the same. Otherwise, the communication is not available. In the case of equipment interconnection, set the communication modes of the interconnected ports to full-duplex. |
| Max Frame Length(bytes) | 64-9600 Default value: 1620 NOTE:
The value ranges of the parameters are different from each other for different boards and products, please refer to the hardware description. |
The Max Frame Length(byte) parameter sets the maximum length of the data packets allowed to be received by the Ethernet port. Impact on the System:After this parameter is set, all the data packets of a length longer than this parameter are discarded. Recommendations:The maximum data packet length has a filtering mechanism, through which this parameter is set to filter the data packets received on the Ethernet port of a length longer than a certain length. When setting this parameter, consider the length of the data packets transmitted from the opposite end. If the parameter value is less than the length of the data packets transmitted from the opposite end, this link cannot normally transmit service packets. |

| Enable Tunnel | Enabled, Disabled Default value: Disabled |
The Enable Tunnel(Ethernet Interface) parameter sets the MPLS enabling state of the port. When Enable Tunnel is set to Enabled, it indicates that the port can identify and process the MPLS label.

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. |
| Specify IP Address | Manually, Unspecified Default value: Unspecified |
The Specify IP Address parameter, set by port, indicates the method of specifying the IP address parameter of a specified port. Impact on the System:The IP address parameter of the port is the prerequisite for MPLS service creation. If the current IP address parameter is invalid, the services cannot be created. Value description:
The IP address parameter can be configured only when the port is in the Layer 3 mode. |
IP Address |
For example, 192.168.0.1 | Specifies the IP address of a port. This parameter is available when Specify IP Address is set to Manually. IP addresses of Ethernet ports on an NE cannot be in the same network segment. IP addresses of the ports at both ends of a link, however, must be in the same network segment. |

MAC Loopback |
Non-Loopback, Inloop, Outloop Default value: Non-Loopback NOTE:
The OptiX OSN equipment supports only Non-Loopback and Inloop. |
This parameter specifies the loopback state at the MAC layer. When this parameter is set to Inloop, the Ethernet signals transmitted to the opposite end are looped back. In normal cases, it is recommended that you use the default value. |
| PHY Loopback | Non-Loopback, Inloop, Outloop Default value: Non-Loopback NOTE:
The OptiX OSN equipment supports only Non-Loopback and Inloop. |
The PHY Loopback parameter indicates the loopback status of the physical layer of an Ethernet port. This parameter is an advanced attribute of the Ethernet port. Impact on the System:As a fault diagnosis function, setting PHY loopback affects the services configured on the port. In the case of loopback, services on the port are interrupted. Value description:
The PHY loopback is mainly used to locate a fault. When setting this parameter, determine the loopback type according to the service flow direction. |

Specifies whether loop detection is enabled. When loop detection is enabled, the equipment automatically detects whether a loop exists on the link. If a loop exists, the equipment reports a loop alarm. |
Loopback Port Block |
Enabled, Disabled |
Specifies whether the automatic port shutdown function is enabled. When Loopback Check is set to Enabled and Loopback Port Block is set to Enabled, the equipment automatically detects whether a loop exists on the link.

Specifies whether the broadcast packet suppression function at the port is enabled to limit the traffic rate of the incoming broadcast packets. If the broadcast packet suppression function is enabled, and if the traffic rate of the incoming broadcast packets exceeds the specified value, the last received broadcast packets are discarded. NOTE:
Enabling Broadcast Packet Suppression is valid for UNI ports only. |
Broadcast Packet Suppression Threshold(Mbit/s) |
0-10000 Default value: 30 |
Allocates the specified bandwidth to the broadcast packets according to the proportion of the broadcast packets in the total packets at the port. If the actual bandwidth of the broadcast packets exceeds the specified threshold, the port discards the last received broadcast packets. |

Specifies the mode of network cables. |
Optical Module Type |
Unknown, Two-Fiber Bidirectional |
Specifies whether an optical module is inserted into a port and the optical module type if yes. Value description:
