Ether Ports > Line

(ONS 15454 only) Use the Ether Ports > Line subtab to display CE-1000-4 Ether Port provisioning information. The Line subtab options are described in the following table.

Port

Displays the card port number.

Port Name

Displays the port name and is also provisionable.

Admin State

Displays the port administration state. 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 IS-NR.

  • OOS,DSBLD-Removes the port from service and disables it. The port service state changes to OOS-MA,DSBLD.

  • OOS,MT-Removes the port from service for maintenance. The port service state changes to OOS-MA,MT.

  • IS,AINS-Puts the port in automatic in-service. The port service state changes to OOS-AU,AINS.

Service State

Displays the 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.

AINS Soak

Automatic in-service soak. Both the hours and minutes can be selected.

Link State

Displays the physical port state. Possible values are UP and DOWN.

Auto Negotiation

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 Ethernet device attached to the card must be set to autonegotiation. If flow control is enabled but the negotiation status indicates no flow control, check the autonegotiation settings on the attached Ethernet device.

Flow Control

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

Flow Control Status

Shows the result of the most recent autonegotiation and the type of flow control that was negotiated.

MTU

Displays the maximum transfer unit, which is the largest acceptable packet size configured for that port.

Water Marks

Provisions the flow control buffer memory levels (water marks):

  • Default: Sets Flow Control Lo and Flow Control Hi to the default settings.

  • Low Latency: Sets Flow Control Lo and Flow Control Hi to the low latency settings. Low latency is best for subrate applications, such as voice-over-IP (VoIP) over an STS-1.

  • Custom: Allows you to enter custom Flow Control Lo and Flow Control Hi values.

Flow Ctrl Lo

Shows the low flow control buffer level for the water marks setting. If you chose Custom from the Water Marks drop-down list, type the desired low flow control buffer level.

Flow Ctrl Hi

Shows the high flow control buffer level for the water marks setting. If you chose Custom from the Water Marks drop-down list, type the desired high flow control buffer level.

Apply

Applies changes made to the port parameters.

Reset

Cancels any changes to the port parameters and returns it to its last-saved settings.

Help

Displays context-sensitive help.
