Thresholds and event notification
28
Counters may fluctuate around the upper or lower boundary of a range threshold, and as a
result cause numerous events in a short period of time. To reduce the number of events,
configure a buffer (a range of values just below the upper boundary and just above the lower
boundary) in which a counter does not register an event if it returns to a “normal” value. An
event only registers if the counter returns to a “normal” value beyond the buffer.
9. Click the right arrow button to move the threshold to the Selected Thresholds list.
If an error is detected, a message displays informing you to enter a valid value. Click OK to
close this message. Fix any errors and repeat step 9.
10. Repeat steps 5 through 9 for each measure that you want to add to the policy.
11. Click Assign fabric level polices to new switches on the Set Threshold Policies dialog box if you
want to assign these policies to new switches.
12. Click OK.
The threshold policy displays in the Available Threshold Policies table with an added icon ( ).
13. Click OK on the Set Threshold Policies dialog box.

The threshold policy displays in the Available Threshold Policies list with an added icon ( )
using “copy of Threshold_Name” as the naming format. To edit the threshold, refer to “Creating
and editing a threshold policy” on page 1108. To assign a threshold policy to a fabric or device,
refer to “Assigning a threshold policy” on page 1111.
