Port
(ONS 15454 only) Use the Port subtab to view and provision the ONS 15454 G1K-4 card port settings.
 
Item
Description
Port
Displays the card port number.
Port Name
Displays the name for the optical port.
Admin State
Shows the administrative state of the port. Choose an administrative state from the drop-down list and click Apply to change the port 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 and 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). For loopbacks, the OOS,MT admin state must be initiated.
IS,AINS—Puts the port in automatic in-service. The port service state changes to Out-of-Service and Autonomous, Automatic In-Service (OOS-AU,AINS).
Note
CTC will not allow you to change a port service state from IS-NR to OOS-MA,DSBLD. You must first change a port to the OOS-MA,MT service state before putting it in the OOS-MA,DSBLD service state.
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.
Media Type
If a Gigabit Interface Converter (GBIC) is attached to the card, indicates the GBIC type: SX, LX, Zx, CWDM, or DWDM. If GBIC is not attached, “unknown” appears.
Flow Control Neg.
(ONS 15454 only) If checked, enables the IEEE 802.3z 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.
Auto Negotiation
If checked, sets the port for autonegotiation. To enable flow control, the port must be set to autonegotiation.
Negotiation Status
Shows the result of the most recent autonegotiation and the type of flow control that was negotiated.
Max Size
Sets the maximum Ethernet frame size:
Jumbo: Accepts jumbo-size Ethernet frames (ranging from the standard 1518 bytes up to 9000 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.
Payload Type
Displays the high-level data link control (HDLC)-based encapsulation for transport of Ethernet traffic over SONET. Options are LAN extension protocol (LEX)-frame check sequence (FCS)-16 (two bytes) and LEX-FCS-32 (four bytes).
TXP Port
(ONS 15454 only) Allows you to choose a port for transponder mode. When you choose a TXP port from the drop-down list, Cisco Transport Controller (CTC) automatically completes the TXP Mode for the ports.
TXP Mode
(ONS 15454 only) When you choose the TXP ports, CTC automatically completes the TXP Mode for the ports, although you can modify CTC’s default selection:
TX/RX—Transmit and receive
RX only—Receive only
TX only—Transmit only
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 Control 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 Control 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.
Link Integrity Disable
Disables link integrity timer.
Link Integrity Timer
Allows to set the link integrity soak timer duration.
Link integrity timer duration can be set in the range between 200 ms and 10000 ms in multiples of 100 ms. Default link integrity soak timer duration is 200 ms.
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.
