POS Ports > Line


(ONS 15310-CL and ONS 15454 only) Use the POS Ports > Line subtab to display packet over SONET Port provisioning information. The Line subtab options are described in the following table.

Port

The port identifier number.

Port Name

The port name. This is the only field that you can provision for the ML-Series card.

Admin State

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.

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. Port service states include:

  • IS-NR-(In-Service and Normal) The port is fully operational and performing as provisioned.

  • OOS-MA,DSBLD-(Out-of-Service and Management, Disabled) The port is out-of-service and unable to carry traffic.

  • OOS-MA,MT-(Out-of-Service and Management, Maintenance) The port is out-of-service for maintenance. Alarm reporting is suppressed, but traffic is carried and loopbacks are allowed.

Link State

The physical port state. Possible values are UP and DOWN.

Framing Type

Shows the encapsulation type set on the Card subtab:

  • HDLC-High-level data link control. Does not support VLAN trunking, which is standard on most Cisco data devices.

  • GFP-F-Frame-mapped generic framing procedure; a protocol data unit (PDU)-oriented adaptation mode that maps a client frame into one GFP frame

  • None-No framing type selected

Encap CRC

Sets the cyclic redundancy check (CRC) to verify the integrity of the transmitted data. Possible values are 32-Bit if the framing type is HDLC, and 32-Bit if the framing type is GFP-F or None.

MTU

Maximum Transfer Unit. The largest acceptable packet size configured for that port. The maximum setting is 9000 and the default size is 1500. The MTU value is 0 until the POS port is used in creating a circuit.

Apply

Applies changes made to the port name.

Reset

Cancels any changes to the port name and returns the field to its last-saved settings.

Help

Displays context-sensitive help.
