    FDDI Applications

    FDDI provides speed and reliability to a LAN and is often used as a backbone technology as well as a means of connecting high-speed computers in a local area. This section describes the views available for the FDDI application.

    There are two FDDI Applications:

    FddiSMT Application FDDI App (RFC 1512App) (Page 10)

    FddiSMT ApplicationThere is one application-specific subview available for the FddiSMT application from the FddiSMT Icon Subviews menu, the FDDI Station List View. This view displays the configuration of the FDDI ring and basic information about the devices in the ring.

    FDDI Station List ViewAccess: From the Icon Subviews menu for the FddiSMTApp Application icon, select Station List.

    The FDDI Station List View displays the configuration of the FDDI ring and basic information about the devices in the ring.

    Station AddressThe address of the ring node. You select canonical or MAC presentation.

    Node ClassThe type of FDDI ring device. Table 2 displays possible Node Class values.

  • F D D I A p p l i c a t i o n s F d d i S M T A p p l i c a t i o n

    D e v i c e M a n a g e m e n t Page 9 T r a n s m i s s i o n A p p l i c a t i o n s

    Ring TopologyThe current state of this FDDI node.

    Master PortsThe number of master ports on this node. Values range from 0 to 255.

    Upstream NeighborThe canonical or MAC address of the last node to receive the token before this node. SMT Rev 6.2 and earlier will specify an unknown address as 00.00.00.00.00.00. SMT revisions after 6.2 will specify an unknown address as 00.00.F8.00.00.00.

    Click on this button to update the table.

    Click on this button to toggle the display of station addresses between MAC (Physical) and Canonical (Ethernet). The button displays the format NOT currently selected.

    Click on this button to set a filter affecting the stations displayed in the table. Choices are Set Filter and Clear Filter. Select an attribute to filter against by clicking one of the column heading buttons.

    Click on this button to sort the stations displayed in the table. Values are Sort Up (default), Sort Down, and Un-Sort. To select an attribute to sort, click one of the column heading buttons.

    Table 2: Node Class Values

    Value Definitions

    FDDI App (RFC 1512App)There is one application-specific subview available for the FDDI App from the RFC1512App Icon Subviews menu, the SMT Device Configuration View.

    SMT Device Configuration ViewAccess: From the Icon Subviews menu for the FddiSMTApp Application icon, select Configuration, or double-click the bottom text label (c) of the icon.

    This view provides two tables displaying FDDI information for the Station Table (below) and MAC Table (Page 14).

    Station TableThis table provides a list of the SMT entries. Double-clicking on any entry in the Station Table accesses a Station Table View, which allows you to modify the selected entry. The Station Table and its corresponding entry-specific views provide the information described below. (Note that you must scroll the Station Table window in order to see all table entries.)

    IndexA unique integer identifier for each SMT. The value for each SMT must remain constant at least

    from one re-initialization of the entitys network management system to the next re-initialization.

    Station IdThe unique identifier for an FDDI station.

    OpVersionIdThe SMT version that this station is using for its operation. The version number is included in the SMT frame so that a receiving station can determine whether or not its SMT version is able to communicate with the SMT version of another station. Knowing the version number allows the stations to handle version mismatches. Each FDDI station supports a range of SMT versions.

    HiVersionIdThe highest version of SMT that this station supports. If a received frame has a version higher than the HiVersionId, the frame is discarded.

    LoVersionIdThe lowest version of SMT that this station supports. If a received frame has a version lower than the LoVersionId, the frame is discarded.

    MIB VersionIdThe SMT version of the FDDI MIB of this station.

  • F D D I A p p l i c a t i o n s F D D I A p p ( R F C 1 5 1 2 A p p )

    D e v i c e M a n a g e m e n t Page 11 T r a n s m i s s i o n A p p l i c a t i o n s

    MAC CtsThe number of Media Access Control (MAC) entities present in this station or concentrator, indicating the number of ring port pairs.

    Non Master CtsThe number of A, B, or S ports on this station or concentrator.

    Master CtsThe number of M Ports in a node. If the node is not a concentrator, the value of the variable is zero. An M port is a port that provides a connection for Single Attachment Station (SAS) devices to the FDDI framework.

    NotifyThe timer, in seconds, used in the Neighbor Notification protocol. This value can range from 2 to 30 seconds, with a default value of 30 seconds. You can modify this field.

    StatRptPolicyIndicates whether the node will generate Status Reporting Frames for its implemented events and conditions. Choices are True or False. If True, Status Reporting Frames will be generated. The initial value is True.

    TraceMaxExpirationThe maximum propagation time, in milliseconds, for a Trace on an FDDI topology. You can modify this field.

    Bypass Present Indicates whether the station has a bypass on its AB port pair. Possible values are True (bypassing) or False (not bypassing).

    ECM StateIndicates the current state of the Entity Coordination Management (ECM), which controls the optical bypass switch and notifies physical connection management when an acceptable connection has been made and the transmission medium is available. The possible ECM states defined below are Out, In, Trace, Leave, Path_Test, Insert, Check, and Deinsert.

    OutWhen Connection Management (CMT) is initialized, the ECM enters the Out state. In this state, the ECM waits for a connect request from SMT. A successful completion of a path test is required to proceed out of the Out state. In the Out state, if an optical bypass switch is present, it is in a bypassed state.

    InThe normal state for a completed connection.

    D e v i c e M a n a g e m e n t Page 12 T r a n s m i s s i o n A p p l i c a t i o n s

    TraceUsed to localize a stuck Beacon condition.

    LeaveUsed to allow sufficient time to break any existing connections.

    Path_TestUsed upon the completion of the Trace function. In this state, the station or concentrator performs a test of its entities and data paths.

    InsertAllows for the switching time of the optical bypass switch. In this state, an insert request is sent to the optical bypass switch. The ECM state remains as Insert until the optical bypass switch has completed switching.

    CheckUsed to confirm that both the primary and secondary optical bypass switches have switched.

    DeinsertAllows time for the optical bypass switch to deinsert.

    CF StateThe attachment configuration for the station or concentrator. There are thirteen possible states. Table 3 describes the possible states and values.

    Table 3: Possible Values for CF State

    Value Definition

    Isolated The port is not inserted into any path.

    Local_a The A port is inserted into a local path and the B port is not.

    Local_b The B port is inserted into a local path and the A port is not.

    Local_ab Both the A and B ports are inserted into a local path.

    Wrap_a The secondary path is wrapped to the A port.

    Wrap_b The primary path is wrapped to the B port.

    C_wrap_a The primary path and secondary paths are joined internal to the node and wrapped to the A port.

    C_wrap_b The primary path and the secondary paths are joined internal to the node and wrapped to the B port.

    D e v i c e M a n a g e m e n t Page 13 T r a n s m i s s i o n A p p l i c a t i o n s

    Remote DisconnectIndicates whether the station was remotely disconnected from the network as a result of receiving a Station Action disconnect in a Parameter Management Frame. A station requires a Connect Action to rejoin and clear the flag. This field displays True when the station has been disconnected, and False when the station has not been disconnected.

    Station StatusThe current status of the primary and secondary paths within this station. Options are Concatenated, Separated, or Thru.

    Peer WrapA configuration management flag indicating that the port has peer wrapped. Options are True or False. Peer wrap is a condition which occurs when a dual-attachment node is wrapped with a Peer mode connection.

    Time StampA time variable to allow rate calculations from counter values. This value may be reset to power change, station self-test, or path-test.

    TransitionTime StampThis variable reflects the time of the most recent event occurrence, condition assertion, or condition deassertion in the station.

    Station ActionWithin an entry-specific view, this button allows you to initiate action on the station. The action options are defined in Table 4.

    Wrap_ab The primary path is wrapped to the B port and the secondary path is wrapped to the A port.

    Thru The primary path enters the A port and emerges from the B port. The secondary path enters the B port and emerges from the A port.

    Local_s The S port is inserted into a local path.

    Wrap_s The primary path is wrapped to the S port.

    C_wrap_s The primary path and secondary paths are joined internal to the node and wrapped to the S port.

    ErrorsThe number of frames that were detected in error by this MAC that had not been detected in error by another MAC.

    Format ErrorsThe number of instances in which this MAC detected a format error during frame reception such that the frame was stripped.

    ThresholdA threshold which, when exceeded, causes the generation of a MAC Condition report. Stations not supporting variable thresholds will have a value of 0. This field can be modified.

    RMT StateThe current state of the Ring Management (RMT) State Machine. The possible states are defined in Table 6.

    Table 6: RMT States

    State Definition

    Ring-Op The ring is functioning normally

    Isolated The device is not attached to the main ring through its A and B ports.

    Non-Op The device is attempting to enter the ring.

    Detect The claim (beacon) process of the FDDI ring protocol has exceeded one second; there may be a problem on the ring. In this state, the ring is still alive, but no data is being transmitted.

    Non-Op-Dup

    The ring is not operational; a duplicate MAC address may have been discovered during the ring initialization process. This state is unlikely to occur unless you are using locally administered addresses, as factory-set MAC addresses are guaranteed to be unique.

    Ring-Op-Dup

    The ring is operational; however, a duplicate address has been detected. Like Non-Op-Dup, this state is unlikely to occur unless you are using locally-administered addresses.

    Directed The beacon process did not complete within 7 seconds. The device is sending directed beacons to notify the other stations that a serious problem exists on the ring, and a Trace state is soon to follow.

    Trace A problem exists on the ring that could not be corrected during the beaconing process, and a Trace has been initiated. During a Trace, the device sends a signal that forces its nearest upstream neighbor to remove from the ring and conduct a self-test.

    Dup AddressIndicates the current status of the duplicate address detection function. Possible states are defined in Table 7.

    Hardware PresentThis variable indicates the presence of underlying hardware support for this MAC object. Possible entries are True or False.

    Table 7: Current Status

    Status Definition

    None Indicates the duplicate address test has not been completed.

    Pass Indicates the duplicate address test has completed and has not detected a duplicate address.

    Fail Indicates the duplicate address test has completed and has detected a duplicate address. This complements the duplicate address detection function of RMT, which operates when the logical ring is not operational.

    Point-To-Point Application

    The Point-to-Point Protocol (PPP) Application provides a method for transmitting datagrams over serial point-to-point links. This section provides access information for the PPP Application Views and describes the view fields available for the PPP application.

    Four PPP application-specific views exist within SPECTRUM. These views can be obtained from the PPP_LCPApp1471 App Icon Subviews menu:

    PPP LCP Application Configuration View (Page 18)

    PPP Link Status Configuration View - Local to Remote Configuration Table (Page 19)

    PPP Link Status Configuration Table View - Remote to Local Configuration View (Page 20)

    PPP Link Status Table View (Page 21)

    PPP LCP Application Configuration ViewAccess: From the Icon Subviews menu for the PPP_LCPApp1471 Application icon, select Configuration.

    Double-clicking an entry in the PPP Link Configuration Table (within the PPP LCP

    Application Configuration View) displays the PPP LCP Configuration View (Page 19).

    Interface Index A unique value assigned to identify the interface on that WAN connection. Not available in the ETWMIM.

    Initial MRUThe initial Maximum Receive Unit (MRU) that the local PPP device advertises to the remote device.

    Receive ACC MapThe Asynchronous-Control-Character-Map (ACC) a local PPP device requires for use on its receive side.

    Transmit ACC MapThe Asynchronous-Control-Character-Map (ACC) a local PPP device requires on its transmit side.

    Magic NumberIndicates whether the local PPP Entity will attempt to perform Magic Number Negotiation with the remote node. Possible entries are true (attempts negotiation), and false (negotiation is not attempted).

    FCS SizeIndicates the size of the Frame Check Sequence (FCS) in bits. The local device attempts to negotiate usage with the remote device.

    PPP LCP Configuration ViewThis View identifies the LCP (Link Control Protocol) configuration parameters for this PPP Link. These variables represent the initial configuration of the PPP Link. The actual values of the parameters change when the link is brought up via the LCP options negotiation mechanism.

    PPP Link Status Configuration View - Local to Remote Configuration Table Access: From the Icon Subviews menu for the PPP_LCPApp1471 Application icon, select Local to Remote Configuration.

    Physical Index The unique value assigned to identify the low-level interface over which this PPP Link is operating. This interface would usually be an HDLC or RS-232 type of interface. If there is no other element that can be identified, then the value of this field is 0. For example, if PPP operates over a serial port there will be two entries in the Table. The PPP could be running over interface number 123 and the serial port could be running over interface number 987. Therefore, ifSpecific.123 would contain the object ID PPP. ETWMIM - refers to this field as PPP Link.

    IF Index A unique value for each PPP Link. The value must remain constant from one re-initialization of the system to the next. ETWMIM refers to this field as PPP Link.

    Table 9: Zero Codes

    Code Description

    JBZS Jammed Bit Zero Suppression, in which the AT&T specification of at least one pulse every 8 bit periods is literally implemented by forcing a pulse in bit 8 of each channel. Thus, only seven bits per channel, or 1.3444 Mbps, are available for data.

    B8ZS Refers to the use of a specified pattern of normal bits and bipolar violations that are used to replace a sequence of eight zero bits.

    ZBTSI May use dsx1ZBTSI, or Zero Byte Time Slot Interchange.

    HDB3 With or without CRC, use dsx1HDB3 or dsx1AMI.

    AMI Refers to a mode wherein no zero code suppression is present and the line encoding does not solve the problem directly. In this application, the higher layer must provide data that meets or exceeds the pulse density requirements, such as inverting HDLC data.
