Configuring Port Threshold Alarms
The Switch Module can monitor a set of port errors and generates alarms based
on user-defined sample windows and thresholds. These port errors include the
following:
 Cyclic Redundancy Check (CRC) errors
 Decode errors
 ISL connection count
 Device login errors
 Device logout errors
 Loss-of-signal errors
You make changes to the port threshold alarms by modifying the Switch Module
configuration as described in “Modify a Switch Module Configuration” on
page 4-66. Refer to Table 20 for a description of the port alarm threshold
parameters.
The Switch Module will down a port if an alarm condition is not cleared within
three consecutive sampling windows (by default 30 seconds). Reset the port to
bring it back online. An alarm is cleared when the threshold monitoring detects
that the error rate has fallen below the falling trigger.
