An FDDI Station PHY Port entity provides the management view of the FDDI Station PHY Port and the FDDI pmd. Each station has at least one PHY port and a concentrator is a device that has at least one phy port of type M. A dual-attached station or dual-attached concentrator has a phy port type A and type B. A single-attached station has a phy port of type B.
1 – character
LEM THRESHOLD Link error monitor threshold. PHY TYPE Type of the physical port A, B, S, or M. This characteristic cannot be set. PMD TYPE Type of the PMD transceiver for this physical port. This characteristic cannot be set. ANSI SONET - unshielded twisted-pair ANSI multimode - low power ANSI multimode type 1 - thinwire ANSI single mode type 2 - shielded twisted-pair
2 – counter
CONNECTIONS COMPLETED Number of times the PHY port entered the in use state, having completed the initialization process. ELASTICITY BUFFER ERRORS Number of times the elasticity buffer function had an overflow or underflow. LCT REJECTS Number of times a connection was rejected due to failure of the Link Confidence Test at either end of the physical connection. LEM REJECTS Number of times an active connection was disconnected due to rejection by the Link Error Monitor at this end of the physical connection, or by expiration of the Noise timer. LINK ERRORS Total number of raw link error input events seen by the Link Error Monitor.
3 – status
BROKEN REASON Reason phy port is in broken state, or if in broken state, none. ESTIMATED LINK ERROR RATE Link error monitor current estimate of error rate. NEIGHBOR PHY TYPE Status may be A, B, S, M or unknown. REJECT REASON Reason the phy port is in a failed or watch state. 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.
