1 HP FDDI/9000 Resources In addition to this manual, use the resources described in this chapter to maintain and administer HP EISA and HSC FDDI/9000.
HP FDDI/9000 Resources About HP EISA FDDI/9000 About HP EISA FDDI/9000 HP EISA FDDI/9000 is a high-performance Fiber Distributed Data Interface (FDDI) networking soluction for HP servers and workstations. HP EISA FDDI/9000 provides the physical and data-link services as defined by the ANSI X3T9.5 specifications for FDDI and is supported over the TCP/IP network protocol stack.
HP FDDI/9000 Resources About HP HSC FDDI/9000 About HP HSC FDDI/9000 HP HSC FDDI/9000 is a high-speed network link offering a dual-attach connection to a Fiber Distributed Data Interface (FDDI) dual-ring network. The product can be run in single-attach mode if only one cable is connected. HSC FDDI/9000 includes FDDI adapter hardware and FDDI driver software and is compliant with ANSI X3T9.5 specifications for FDDI.
HP FDDI/9000 Resources FDDI Concepts FDDI Concepts The Fiber Distributed Data Interface (FDDI) is a high speed local area network which has been defined as a standard by an American National Standards Institute committee, ANSI X3T9.5 and by ISO. FDDI is a 100 Mbps, token-passing, single or dual ring interface that can be implemented with Fiber Optic or Unshielded Twisted-Pair (UTP) media. A Timed Token Protocol (TTP) is used to control when a station can transmit data to the network.
HP FDDI/9000 Resources FDDI Concepts Figure 1-1 FDDI Architecture Dual Ring Concentrator Concentrator DAC DAC SAS DAS DAS SAC Concentrator SAS SAS SAS FDDI-LAN Bridge SAS SAS FDDI Devices To promote ease of installation and maintenance, FDDI allows for several types of networking devices. These include dual ring and single ring concentrators, and dual ring and single ring stations. Concentrators are the building blocks of an FDDI network.
HP FDDI/9000 Resources FDDI Concepts • Single Attachment Station (SAS): Connects only to the primary ring. Generally, a SAS connects to the FDDI ring through a DAC. Network designers and administrators are given the opportunity to balance the costs of installation and operation with the quality of service demanded by each segment. For example, a dual set of fiber running between stations is much more expensive than connecting the stations with a single fiber.

Troubleshooting If you cannot solve the problem on your own, contact your HP representative. Use the guidelines in the section “Contacting Your HP Representative” in Chapter 1 to help you effectively communicate what is wrong.
Troubleshooting Using the fddilink Utility Using the fddilink Utility The fddilink utility is used to display the operating characteristics of an FDDI network. The monitor provides information about the node on which the program is loaded, the upstream and downstream neighbors, the ring state, the token rotation times, and so forth. It can be run from a remote shell where the shell is located on a system that contains an adapter.
Troubleshooting Using the fddilink Utility PHY: ConPol Cutoff Alarm A 0000 7 8 B 0000 7 8 T-MAX Low: 1336.934 ms TVX Low: 5.222 ms T-Req : 165.007 ms T-Neg : 165.000 ms T-Max : 167.772 ms TvxValue : 2.
Troubleshooting Using the fddilink Utility • CFM describes the internal configuration of ports and MACs within a station or concentrator. The CFM state can be one of the following: • WRAP_A, WRAP_B, WRAP_AB, C_WRAP_A, and C_WRAP_B states indicate that there is only a single data ring. Data for the ring is transmitted and received through the same port (A or B).
Troubleshooting Using the fddilink Utility • DIRECTED indicates that this MAC sends beacon frames to notify the ring of a stuck condition. • TRACE indicates that this MAC initiates a trace function. Trace provides a recovery mechanism from a stuck beacon. • ManufactureData indicates the manufacturer of the communication adapter or node. • UserData indicates the communication board used by the node. • SMT Version Op indicates the field in the SMT header that identifies the structure of the SMT Info field.
Troubleshooting Using the fddilink Utility • RemoteMAC indicates the presence (1) or absence (0) of a MAC whose transmit path exits the station via this port. There can be only one present at any one time. • PCM indicates the state of the Physical Connection Management (PCM) for this node. The possible values are Disable, Connect, Standby and Active. • LER indicates Link Error Rate. It ranges from 10-4 to 10-15.
Troubleshooting Using the fddilink Utility The information displayed on this menu includes whether the node is a single or dual attach station, if an optical bypass is present, and shows the I_Max Expiration time. The Delay Menu [9:Delay] This feature allows the user to set the rate measured in seconds, for which the information on the fddilink screens is updated. To set the delay rate, enter the desired rate in seconds, and press Enter.
Troubleshooting Using the fddiif Utility Using the fddiif Utility The fddiif utility is used to collect operating statistics in real-time on the FDDI adapter driver. To invoke the fddiif utility, enter the following: fddiif lanx where x is the instance number of the adapter. A sample console output is shown below. \ Hit Ctrl-C to quit any time.
Troubleshooting Troubleshooting Troubleshooting The following table describes various symptoms and corrective actions for the HP EISA or HSC FDDI adapter. Table 5-1 Symptoms and Actions Symptom Card fails power-up test. Action • Inspect the LEDs on the back of the adapter. A constant, solid LED (4) indicates a failure in the power-up diagnostics. For HSC FDDI, solid LEDs (2) and (3) indicate power-up diagnostics succeeded. For EISA FDDI, solid LEDs (1) and (3) indicate power-up diagnostics succeeded.
Troubleshooting Troubleshooting Symptom Adapter cannot communicate with other hosts on the local network. Action • Use fddilink to verify that upstream and downstream neighbors are correct. • Examine the LEDs. • Check the FDDI cable. Make sure the FDDI media is correctly installed. ping the failed system from another host on the network. • Distinguish between an unknown host, which indicates a /etc/hosts file problem; and a non-response, which usually indicates a routing problem.
Troubleshooting Troubleshooting Symptom Cannot reach a host on a remote network. Action • Use ping to test connectivity to stations on your local ring. • Distinguish between an unknown host, which indicates a /etc/hosts file problem; and a non-response, which usually indicates a routing problem. • Use fddilink to see if you are communicating with your upstream and downstream neighbors on the ring. • Check the arp table with arp -a. • Use netstat -r to check routing tables.

B Fiber Cabling FDDI can be transported over multiple types of physical media. The most common media includes optical fiber.
Fiber Cabling Fiber Optic Cable Fiber Optic Cable Fiber optic cable consists of a glass cylinder core, surrounded by a tube of dissimilar glass with an outer coating of protective material. The core is composed of optically pure glass that is used to transmit the light waves that carry the data. The cladding that surrounds the core is a special glass coating designed to reflect the light waves back into the core.
Fiber Cabling Fiber Optic Cable Fiber Optic Cable Maintenance Fiber optic cable requires proper handling. Follow these basic guidelines in addition to manufacturers specifications for good cable maintenance: • Do not stretch, puncture, or crush the fiber cable(s) with staples, heavy equipment, doors, etc. • Always maintain the minimum bend radii specified by the cable manufacturer. The minimum bend radii is usually 10-20 times a cable’s outer diameter.
Fiber Cabling Connectors Connectors HP HSC EISA FDDI/9000 adapters use MIC connectors. HP HSC FDDI/9000 adapters use SC connectors.
Glossary 4B/5B The physical layer (PHY) coding scheme for FDDI. 802.1 IEEE A set of standards for governing the OSI Data Link layer and the OSI physical layer. For example, 802.1d is the standard for bridging between the LAN standards 802.2 IEEE Standards that govern the Logical Link Control (LLC) within the Data Link layer of the OSI model. LLC frames carry user infobetween two stations. These standards are common across the various lower level standards within the Data Link and the Physical layers.
Glossary the bandwidth, the more information can be sent through a circuit during a given amount of time. C baud Measurement of signaling Connection Management (CMT) within the Station Management (SMT) function of an FDDI station that provides for the configuration of PHY and MAC entities within a node. speed indicating line changes per second, where line changes can represent one or more bits. The baud is equal to bits-per-second only for line changes representing a single bit.
Glossary CPU (Central Processing Unit) A computer’s main microprocessor chip. CRC (Cyclic Redundancy Check) An error checking procedure in which bytes at the end of a frame are used by the receiving node to detect a transmission problem. polarity change at the start of the bit time; a one is represented by no polarity change at the start of the bit time. DMA (Direct Memory Access) A fast method of moving data between two processor subsystems without processor intervention.
Glossary downstream A term that refers to the relative position of two stations in a ring. A station is downstream of its neighbor if it receives the token after its neighbor receives the token. dual homing A method of cabling concentrators and stations that permits an alternate or backup path to the dual ring in case the primary connection fails. Can be used in a tree or dual ring of trees configuration. Connection Management) that the medium is available, and coordinating trace functions.
Glossary fiber optics The technique of using H fiber optic transmitters, receivers, and cables for the transmission of data. header Control information added Float Signal is placed in the high impedance state. fragmentation A process in which large frames from one network are broken up into smaller frames that are compatible with the frame size requirements of the network to which they will be forwarded. at the data source to allow data to reach its destination.
Glossary I ISO (International Standards Organization) An international ICMP (Internet Control Message Protocol) An integral body that creates networking standards, including the Open Systems Interconnection (OSI) model. part of the Internet Protocol (IP) that handles error and control messages. Specifically, gateways and hosts use ICMP to send reports of problems with datagrams back to the original source of the datagram.
Glossary M MIC (Media Interface Connector) An optical fiber MAC (Media Access Control) connector pair that links the fiber media to the FDDI node or another cable. The MIC consists of two halves. The MIC plug terminates an optical fiber cable. The MIC receptacle is associated with the FDDI node. The Data Link layer in the ISO model that describes how devices share access to a network. Ethernet, token-ring, and FDDI are MAC layer specifications. Wiring hubs deal primarily with MAC layer equipment.
Glossary Management (SMT) function of an FDDI station that periodically announce their addresses to downstream neighbors. Each station in the ring makes such an announcement every 30 seconds by sending a NIF that uses Next Station Addressing (NSA), a special addressing mode that permits a station to send a frame to the next station on the token path without knowing the address of that station.
Glossary P packet Data information that is grouped and transmitted together, such as messages, commands, and control codes. PCM (Physical Connection Management) That portion of the Connection Management (CMT) within the Station Management (SMT) function of an FDDI station that manages the physical connect between adjacent PHYs. This includes the signaling of the connection type, link confidence testing, and the enforcement of connection rules. peer-to-peer Assigning of entity).
