Avoiding port fencing inheritance
When you directly assign a threshold to an object, the threshold is inherited by all subordinate
objects in the tree (unless they already have directly assigned thresholds). You cannot remove an
inherited threshold from a subordinate object. However, the Management application allows you to
effectively avoid inheritance for individual subordinate objects while maintaining inheritance for
other subordinate objects. To avoid inheritance for an individual subordinate object, you must
create a new threshold with a maximum limit of events allowed and a minimum time period, then
assign the new threshold to the subordinate object.
To turn off port fencing inheritance, complete the following steps.
1. Select Configure > Port Fencing.
The Port Fencing dialog box displays.
2. Select a threshold type from the Violation Type list.
3. Click Add.
The Add <Type> Threshold dialog box displays.
4. Type a name for the new threshold (for example, AvoidProtocolError) in the Name field.
5. Select or enter the maximum number of errors or violations allowed in the Threshold
errors/violations field.
6. Select the minimum time period available from the Threshold minutes/seconds list.
7. Click OK on the Add <Type> Threshold dialog box.
8. Click OK on the Port Fencing dialog box.
Editing thresholds
The Management application allows you to edit the name, number of events needed, and time
period of ISL Protocol, Link, and Security thresholds.
