The station-name must be a simple name which uniquely
identifies a particular station instance. The port-index
can be either an integer or a wildcard.

show fddi station fddi-0 phy port 0 all

1 – Characteristics
o lem threshold
Value: For n, 10 to the -n th power
Link error monitor threshold.
o phy type
Type of the physical port (A, B, S, or M). This characteristic
cannot be set.
o pmd type
Type of the PDM (transceiver) for this physical port. This
characteristic cannot be set.
ANSI multimode Low power
ANSI multimode type 1 Thinwire
ANSI single mode type 2 Shielded twisted-pair
ANSI SONET Unshielded twisted-pair
2 – Counters
o creation time
Time at which the port was created.
o connections completed
Number of times the PHY port entered the in use state, having
completed the initialization process.
o elasticity buffer errors
Number of times the elasticity buffer function had an overflow or
underflow.
o lct rejects
Number of times a connection was rejected due to failure of the
Link Confidence Test at either end of the physical connection.
o 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.
o link errors
Total number of raw link error input events seen by the Link
Error Monitor.
3 – Identifier
o index
An integer that uniquely identifies this physical port to the
parent station entity.
4 – Status
o broken reason
Reason phy port is in broken state, or if in broken state, none.
o estimated link error rate
Default: 15 Value: 0-15
Reports the number of errors during the Link Monitor Test as a
negative power of 10. If there are no errors during the Link
Monitor Test, then the Estimated Link Error Rate is 10(-15th power).
An Estimated Link Error Rate of 15 indicates an excellent/clear
link, 14-10 is a noisy link and around 7 would indicate an
acceptable (failed) link.
o neighbor phy type
Status may be A, B, S, M or unknown.
o 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.
LCT both Link Confidence Test failed on both sides of the
sides physical connection.
LCT protocol Neighboring physical port has been detected to
error have prematurely exited the link confidence test
(LCT).
LEM reject Link error monitor disconnected this connection
due to the error rate exceeding the LEM threshold.
local LCT Link Confidence Test failed on this end of the
physical connection.
noise reject Noise timer expired because a single noise event
lasted for more than 1.31072 ms.
none No reason.
remote LCT Link Confidence Test failed on the other end of
the physical connection.
remote Neighboring physical port broke the connection for
reject an unknown 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.
topology Neighboring physical port's physical port type is
reason an illegal match for this physical port's physical
port type.
trace in Physical port was initializing when a pc-trace
progress 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.
trace Physical port was momentarily disabled because it
received- received a pc-trace when its own pc-trace function
disabled was disabled. The pc-trace function is enabled by
default. The trace disable switch is not remotely
manageable.
o state
Operational state of the phy port entity (nonsettable).
broken The physical port has failed initialization tests
and is not available for use.
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.
internal The physical port has been configured to
loopback 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.
in use The physical port has established a connection and
is fully operational. Communications services are
now available.
off-ready The physical port is waiting to be enabled or has
been disabled by management request.
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.
waiting The physical port is beginning to establish a
connection and is waiting for a response from the
neighboring physical port.
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.
o uid
Entity's unique identifier, which is generated when the entity is
created.
