Configuring Port Threshold Alarms
The switch can monitor a set of port errors and generates alarms based on
user-defined sample windows and thresholds. These port errors include the
following:
ī Cyclic Redundancy Check (CRC) errors
ī Decode errors
ī ISL connection count
ī Device login errors
ī Device logout errors
ī Loss-of-signal errors
You make changes to the port threshold alarms by modifying the switch
configuration as described in āModifying a Switch Configurationā on page 5-13.
Refer to Table 14-23 for a description of the port alarm threshold parameters.
The switch 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.
