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.
