160 Command Line Interface
threshold
Initiates a configuration session by which to generate and log alarms for selected events. The
system displays each event, its triggers, and sampling window one line at a time and prompts
you for a value. For each parameter, enter a new value or press Enter to accept the current value
shown in brackets. These parameters must be saved in a configuration and activated before they
will take effect. Refer to the Config command for information about saving and activating a
configuration. Table 47 describes the Set Config 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.
