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,

connection will become active if the B to M
connection is lost.

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.

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.
