Port

Use the Port subtab to provision Ethernet port information for ONS 15600 ASAP card Ethernet ports.

Port

The PPM number.

Port Name

Name for the optical port.

Admin State

Shows the administrative state of the port. Choosing an administrative state from the drop-down list and clicking Apply changes the port's service state unless network conditions prevent the change. Admin states include:

  • IS-Puts the port in service. The port service state changes to In-Service, Normal (IS-NR).

  • OOS,DSBLD-Removes the port from service and disables it. The port service state changes to Out-of-Service and Management, Disabled (OOS-MA,DSBLD).

  • OOS,MT-Removes the port from service for maintenance. The port service state changes to Out-of-Service and Management, Maintenance (OOS-MA,MT).

  • IS,AINS-Puts the port in the Out-of-Service and Autonomous, Automatic In-Service (OOS-AU,AINS) service state. Alarms and conditions are suppressed. When the port receives a valid signal, the service state automatically changes to IS-NR.

Service State

An autonomously generated state that gives the overall condition of the port. Service states appear in the format: Primary State-Primary State Qualifier, Secondary State. For additional state information, see States.

Link State

The physical port state. Possible values are Up and Down.

Enable Flow Control

If checked, enables the IEEE 802.3x flow control and buffering to reduce data congestion on the port (default). If flow control is enabled, the port must be set to autonegotiation. If flow control is enabled but the negotiation status indicates no flow control, check the autonegotiation settings.

Flow Control

The negotiated flow control mode. Possible values are None, Symmetrical, and Asymmetrical.

Enable Auto Negotiation

If checked, sets the port for autonegotiation. To enable flow control, the port must be set to autonegotiation.

Max Size

Sets the maximum Ethernet frame size:

  • 9600: Sets the maximum Ethernet frame size at 9600 bytes.

  • 1548: Sets the maximum Ethernet frame size at 1548 bytes. This size enables the port to accept valid Ethernet frames that use protocols, such as Inter-Switch Link (ISL). ISL adds 30 bytes of overhead and might cause the frame size to exceed the traditional 1518 byte maximum.

Flow Control Lo

Shows the low flow control buffer level for the water marks setting. Type the desired low flow control buffer level.

Flow Control Hi

Shows the high flow control buffer level for the water marks setting. Type the desired high flow control buffer level.

Reach

Displays the reach value. The reach distances follow:

  • Auto Provision-The system automatically provisions the reach from the PPM reach value on the hardware.

  • SX-Up to 550 m or 270 m distance based on 50um/62.5um diameter fiber.

  • LX-Up to 10 km or 550 m distance based on 50um/62.5um diameter fiber.

  • DX-Up to 40 km distance.

  • HX-Up to 40 km distance.

  • ZX-Up to 80 km distance.

  • VX-Up to 100 km distance.

Wavelength

Displays the wavelength frequency.

Apply

Applies changes made to the fields in the tab.

Reset

Cancels any changes to the tab and returns the fields to their last-saved settings.

Help

Displays context-sensitive help.
