Port Management
The Port Management section of the FDDI Port Configuration View provides
the following information:
Port Action
Allows you to enable and disable the port. The state returns to Other once the
port has been enabled or 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
representing the exponent. 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 3-1.

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.
