Enabled/Disabled.
Port State
The status of this port. Possible states are:
disabled, connecting, standby, and active.
Port Type
The type of port. Possible port types are: A_Port,
B_Port, Slave, or Master.
Link Error Rate Estimate
The link error rate estimate is a cumulative long-
term average of the bit error rate, which
represents the quality of the physical link. The
link error rate estimate is computed when the
port is connected and every 10 seconds thereafter.
It ranges from 10
-4
to 10
-15
and is reported as a
whole integer. For example, if the port’s link error
rate estimate is computed to be 10
-5
, the value
reported in this field would be 5, which represents
an actual rate of 1,250 bit errors per second. A
lower link error rate estimate indicates a higher
bit error rate as shown in Figure 22.

Link Error Monitor Count
The aggregate link error monitor count. This
count is set to zero on station power up and
increments each time the port’s link error monitor
detects an error. An increasing link error monitor
count usually indicates a problem with the
connectors or the cable between this port and the
node.
Link Error Rate Cutoff
The link error rate threshold at which a link
connection is flagged as faulty and the port
disabled by SMT. The default link error rate cutoff
threshold is 7, which represents 12.5 bit errors
per second.
