Setting Up Port PHY Parameters

Article Summary

You can view both SFP and copper ports, and set up the PHY parameters for each port. The PHY parameters are used to set the abilities that are advertised to the link partner.

▶ To view PHY parameters

  1. Access the page Port ▶ PHY.
    A list of PHY configuration and status for all ports is displayed.

  2. (Optional) To limit the view to only certain PHY configurations, enter a value on which to filter, then click Search. You can filter by the port name, connector type, whether or not auto-negotiation is enabled, or the port's auto-negotiation state.


    Note: Enter an asterisk ( * ) as a wildcard to replace one or several characters.

For more information on specific parameters, refer to the following table.

Port Configuration (Port ▶ PHY)

ParameterDescription
StatusThe port status may be one of the following:
  • Green: The port is up and running
  • Blue: The port is enabled and a signal is detected
  • Red: The port is enabled but the physical link is down and no signal is detected
  • Yellow: The port is not totally functional
  • Gray: The port is disabled
ConnectorThe physical connector the port is using.

If the physical connector is reported as Unknown, it means that the remote device is unlinked and that the information shown is cached from the last communication made with the remote device.

Port nameThe logical name assigned to the port.
Auto-negoIndicates whether the auto-negotiation feature is enabled or disabled

If enabled, the Skylight sensor: control automatically negotiates port speed and duplex type with the device to which it is connected. For auto-negotiation to be successful, the device and its partner must both be configured to support auto-negotiation (Port Configuration).

StateThe current auto-negotiation state of the port

▶ To set up a port’s PHY parameters

  1. Access the page Port ▶ PHY.
    A list of PHY configuration and status values for all ports is displayed.

  2. (Optional) To limit the view to only certain PHY configurations, enter a value on which to filter, then click Search. You can filter by the port name, connector type, whether or not auto-negotiation is enabled, or the port's auto-negotiation state.


    Note: Enter an asterisk ( * ) as a wildcard to replace one or several characters.

  3. Click the Port Name to edit its settings.

  4. Define the port PHY parameters as required by your setup, then click Apply.

For more information on specific parameters, refer to the following table.

PHY Configuration (Port ▶ PHY ▶ [port name])

ParameterDescription
Advertisement configurationThe abilities that are advertised to the link partner.

Possible options include:

  • 10 Mbps Half
  • 100
  • Mbps Half
  • 1 Gbps Half
  • 10 Gbps Half
  • 10 Mbps Full
  • 100 Mbps Full
  • 1 Gbps Full
  • 10 Gbps Full
  • Pause Symmetric (able to receive and transmit pause frames
  • Pause Asymmetric (able to either receive or transmit pause frames)

Note: Unsupported options, if any, are disabled.

Link partner abilityThe abilities of the link partner.

Possible options include:

  • 10 Mbps Half
  • 100
  • Mbps Half
  • 1 Gbps Half
  • 10 Gbps Half
  • 10 Mbps Full
  • 100 Mbps Full
  • 1 Gbps Full
  • 10 Gbps Full
  • Pause Symmetric (can receive and transmit pause frames
  • Pause Asymmetric (can either receive or transmit pause frames)

Note: Unsupported options, if any, are disabled.

StateThe state field corresponds to ifMauAutoNegConfig and ifMauAutoNegRemoteSignaling from RFC-3636.

The disabled state indicates that auto-negotiation is not supported by the media or is disabled by the configuration. Possible values are:

  • Other
  • Configuring
  • Complete
  • Disabled
  • Parallel Detect Fail
  • Not applicable (for Skylight sensor: SFP compute 10G module that does not support auto-negotiation)
