1 FDDI =title FDDI The FDDI module implements one of multiple possible Link level/Network level modules in the OSI layered architecture model. Fiber Distributed Data Interface FDDI is the basis for the second generation of network interconnect architecture for Digital. The FDDI module implements one of the multiple possible Link level/Physical level modules in the OSI layered architecture model. The FDDI Physical level includes high-speed, 125 megabaud, fiber optic links which may be many kilometers in length. The FDDI Link level provides a high bandwidth, 100 megabits per second local area network LAN, and uses the ANSI standard FDDI Token Ring. The hierarchical relationship of the entities that constitute the FDDI module: FDDI Port Station Link Phy Port The FDDI module incorporates the functions and operations defined in the ANSI FDDI Token Ring Media Access Control MAC, the ANSI FDDI Token Ring Physical Layer Protocol PHY, FDDI Physical Layer Medium Dependent PMD, Station Management SMT specifications, parts of the ISO 8802-1 IEEE 802.1 Addressing, Internetworking and Network Management, and parts of the ISO 8802-2 IEEE 802.2 Logical Link Control LLC specifications. The FDDI entity is the top-level entity in the hierarchy of entities belonging to the FDDI module. 2 character =title Characteristic Attributes VERSION Version number of the FDDI architecture specification to which the implementation conforms. You cannot modify this characteristic. 2 station =title FDDI STATION An FDDI Station entity represents an access point to the service offered by the FDDI module.

LCT REJECTS Number of times a connection was rejected due to failure of the Link Confidence Test at either end of the physical connection.

This is not meaningful when phy port is in some other state. NONE - No reason. STANDBY - Physical port and its neighboring physical port form a redundant physical connection dual-homing feature. In a dual-homed configuration, the B to M connection is the higher priority physical connection, and the A to M connection is the standby physical connection. The standby connection will become active if the B to M connection is lost. LOCAL LCT - Link Confidence Test failed on this end of the physical connection. REMOTE LCT - Link Confidence Test failed on the other end of the physical connection. LEM REJECT - Error monitor disconnected this connection due to the error rate exceeding the LEM threshold. NOISE REJECT - Noise timer expired because a single noise event lasted for more than 1.31072 ms. REMOTE REJECT - Neighboring physical port broke the connection for an unknown reason. LCT BOTH SIDES - Link Confidence Test failed on both sides of the physical connection. TOPOLOGY REASON - Neighboring physical port's physical port type is an illegal match for this physical port's physical port type. TRACE IN PROGRESS - Physical port was initializing when a pc-trace occurred. When a pc-trace occurs, any physical ports that have not yet established a physical connection are shut down to prevent the topology from changing. LCT PROTOCOL ERROR - Neighboring physical port has been detected to have prematurely exited the link confidence test LCT. TRACE RECEIVED-DISABLED - Physical port was momentarily disabled because it received a pc-trace when its own pc-trace function was disabled. The pc-trace function is enabled by default. The trace disable switch is not remotely manageable. STATE Operational state of the phy port entity nonsettable. IN USE - The physical port has established a connection and is fully operational. Communications services are now available. BROKEN - The physical port has failed initialization tests and is not available for use. WATCH - Same as starting, except the physical port has failed to complete the last connection attempt. Refer to the physical port's status parameter, reject reason for the reason for connection failure. Connection attempts will continue until successful. FAILED - Same as waiting, except the physical port has failed to complete the last connection attempt. Refer to the physical port's status parameter reject reason for the reason for connection failure. Connection attempts will continue until successful. WAITING - The physical port is beginning to establish a connection and is waiting for a response from the neighboring physical port. STARTING - The physical port has received a response from the neighboring physical port and is exchanging information and performing the link confidence test LCT prior to completing the connection. OFF-READY - The physical port is waiting to be enabled or has been disabled by management request. INTERNAL LOOPBACK - The physical port has been configured to internally present all transmitted symbols to the receive interface. The network connector is inactive. This allows internally generated test frames to be looped back for test purposes. 2 port =title FDDI Port An FDDI Port entity represents an access point to the service offered by the FDDI module.
