Parameter Description: Attributes of Ethernet Ports

Parameter Description: Attributes of Ethernet Ports

This topic describes the attributes of Ethernet ports.

Basic Attributes

Before configuring Ethernet services in packet mode, you need to set the basic attributes of Ethernet ports.

Table 3-318  Parameters for the basic attributes of an Ethernet port

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:
  • Enabled: The port is usable.
  • Disabled: The port is unusable.
Recommendations:

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.

  • If this field is set to Layer 2, the port can be used to receive Ethernet services from the user equipment or to transmit Ethernet services that exclusively occupy the port.
  • If this field is set to Layer 3, the port can carry tunnels.
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:
  • Null: No link layer is available, or the link layer encapsulation is not processed.
  • 802.1Q: In the Layer 2 mode, the encapsulation type of the Ethernet port is 802.1Q by default.
  • QinQ: When the Ethernet port is used for QinQ Link, the port attribute should be set to Layer 2, and the encapsulation type should be set to QinQ. In addition, QinQ Type Domain of the two interconnected Ethernet ports should be set to the same value.
Recommendations:

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:
  • For the OptiX OSN 500 equipment, this field cannot be set to 10G Full-Duplex LAN or 10G Full-Duplex WAN.
  • For the OptiX OSN 580 equipment, this field cannot be set to 10M Half-Duplex, 100M Half-Duplex or 10G Full-Duplex WAN.

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:
  • 10M Half-Duplex: The maximum transmission rate of the port is 10 Mbit/s and the communication mode is half-duplex.
  • 10M Full-Duplex: The maximum transmission rate of the port is 10 Mbit/s and the communication mode is full-duplex.
  • Auto-Negotiation: The port uses the protocol to automatically specify the best working mode that matches the opposite port for communication.
  • 100M Half-Duplex: The maximum transmission rate of the port is 100 Mbit/s and the communication mode is half-duplex.
  • 100M Full-Duplex: The maximum transmission rate of the port is 100 Mbit/s and the communication mode is full-duplex.
  • 1000M Full-Duplex: The maximum transmission rate of the port is 1000 Mbit/s and the communication mode is full-duplex.
  • 10G Full-Duplex LAN: The maximum transmission rate of the port is 10 Gbit/s and the communication mode is full-duplex. This value is applicable to the Ethernet port.
  • 10G Full-Duplex WAN: The maximum transmission rate of the port is 10 Gbit/s and the communication mode is full-duplex. This value is applicable to the SDH port.
Recommendations:

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.

Auto-Negotiation Ability

This field is available only when Encapsulation Type in General Attributes is set to QinQ.

Tag

Tag Aware, Access, Hybrid

Default value: Tag Aware

Identifies the type of packets.

  • Tag Aware: If the port is set to Tag aware, the port transparently transmits the packets with a VLAN ID (namely, tagged packets) and discards the packets without a VLAN ID (namely, untagged packets). At this time, Default VLAN ID and VLAN Priority are unavailable.
  • Access: If the port is set to Access, the port attaches the default VLAN ID to the packets without a VLAN ID (namely, untagged packets) and discards the packets with a VLAN ID (namely, tagged packets).
  • Hybrid: If the port is set to Hybrid, the port attaches the default VLAN ID to the packets without a VLAN ID (namely, untagged packets) and transparently transmits the packets with a VLAN ID (namely, tagged packets).

This field is unavailable if Encapsulation Type in General Attributes is set to QinQ.

Default VLAN ID

1-4094

Default value: 1

Specifies the default VLAN ID of the packets that can be transmitted by the port.

  • If TAG is set to Access, the port discards the packets that contain the VLAN ID, but attaches the default VLAN ID to the packets that do not contain a VLAN ID and then transmits these packets.
  • If TAG is set to Hybrid, the port transmits the packets that contain a TAG, and attaches the default VLAN ID to the packets that do not contain a TAG and then transmits these packets.

VLAN Priority

0-7

Default value: 0

Specifies the quality of service. For example, on a busy network, the higher-priority packets are processed first whereas the lower-priority packets may be discarded. The value 0 indicates the lowest priority, and the value 7 indicates the highest priority.

The default value is recommended unless otherwise specified.

Table 3-320  Methods used by Ethernet interfaces to process data frames
Port Type of Data Frame Processing Method
Tag Aware Access Hybrid
Ingress UNI Tagged frame The port receives the frame. The port discards the frame. The port receives the frame.
Untagged frame The port discards the frame. The ports add the VLAN tag, to which Default VLAN ID and VLAN Priority correspond, to the frame and receive the frame. The ports add the VLAN tag, to which Default VLAN ID and VLAN Priority correspond, to the frame and receive the frame.
Egress UNI Tagged frame The port transmits the frame. The port strips the VLAN tag from the frame and then transmits the frame.
  • If the VLAN ID in the frame is Default VLAN ID, the port strips the VLAN tag from the frame and then transmits the frame.
  • If the VLAN ID in the frame is not Default VLAN ID, the port directly transmits the frame.

Layer 3 Attributes

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:
  • Manually: Indicates the IP parameter of the specified port. If the IP address parameter is valid, specify an IP address to the current port. If the IP address is invalid, release the IP address of the current port.
  • Unspecified: Indicates that the IP address of the port is not specified.
Association with other parameters:

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.

IP Mask

For example, 255.255.255.0

Specifies the subnet mask of a port.

This parameter is available when Specify IP Address is set to Manually.

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:
  • Non-Loopback: Indicates the normal status. When the equipment is operating normally, loopback is not required.
  • Inloop: At the local equipment, the outgoing services of an Ethernet port are looped back at the physical layer and input to this Ethernet port.
  • Outloop: At the local equipment, the incoming services of an Ethernet port are looped back at the physical layer and output to this Ethernet port.
Recommendations:

The PHY loopback is mainly used to locate a fault. When setting this parameter, determine the loopback type according to the service flow direction.
