Inheriting alert parameters from a switch
When you enable bottleneck detection on a switch, all eligible ports on that switch inherit the same
bottleneck parameters as the switch. You can then change the parameters for specific ports or
exclude specific ports from bottleneck detection.
Use the following procedure if you want to restore the switch bottleneck parameters to a port that
has direct assigned settings.
1. Select Monitor > Performance > Bottlenecks.
The Bottlenecks dialog box displays.
2. Select a port that has directly assigned bottleneck settings, which is indicated by a right arrow
in the Direct Assigned column.
3. Click Inherit From Switch.
4. Select the Alerts check box to enable alerts. Clear this check box to disable alerts.
The bottleneck parameters that are specified for the switch are applied to the port.
5. Click OK or Apply to save your changes.
Copying alert parameters from one switch or port to another

3. Click the left arrow.

4. Select one or more switches, ports, or fabrics to which you want to copy the bottleneck
parameters.
You can select fabrics or switches or ports, but you cannot select a mix of fabrics, switches,
and ports.
5. Click the right arrow.
The bottleneck parameters are applied to the selected items.
6. Click OK or Apply to save your changes.
