Brocade Communications Systems IP250 Unblocking a port, Avoiding port fencing inheritance

20 Adding thresholds

1.Select Monitor > Fabric Watch > Port Fencing. The Port Fencing dialog box displays.

2.Select a threshold type from the Violation Type list.

3.Select the threshold you want to assign from the Thresholds table.

4.Select the objects (All Fabrics, Fabric, Director, Switch, Port Type, and/or Port) to which you want to assign the threshold from the Ports table.

5.Click the right arrow.

A directly assigned icon ( ) displays next to the objects you selected in the Ports table to show that the threshold was applied at this level and was inherited by every subordinate object below it in the tree (if not affected by lower level direct assignments).

An added icon () appears next to every object in the tree to which the new threshold is applied.

6.Click OK on the Port Fencing dialog box.

Unblocking a port

The Management application allows you to unblock a port (only if it was blocked by Port Fencing) once the problem that triggered the threshold is fixed. When a port is blocked an Attention icon () displays next to the port node.

To unblock a port, complete the following steps.

1.Select Monitor > Fabric Watch > Port Fencing. The Port Fencing dialog box displays.

2.Right-click anywhere in the Ports table and select Expand.

3.Select a blocked port from the Ports table.

4.Click Unblock.

5.Click OK on the message.

If you did not solve the root problem, the threshold will trigger again.

6.Click OK on the Port Fencing dialog box.

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 Monitor > Fabric Watch > Port Fencing. The Port Fencing dialog box displays.
