Optional Features box, you cannot enter a value into the Threshold % column for the port. If you click the check box to remove the checkmark, any value that was set in the Threshold % column for the port will redisplay. - Click in the Threshold % column and enter a value in the range of 1 through 99. Note: If no threshold is entered for a port, a default value is used that is based on port type (1 Gb/sec or 2 Gb/sec) and channel bandwidth. This field cannot be left blank. 4. Set Event Notification options. Note: If enabled, these notifications occur the first time the events occur. Notifications are not resent while the problem persists. - Unresolved Congestion. Click this check box to display a checkmark and enable notification. If enabled, an "unresolved congestion" entry is made to the Event Log and an SNMP trap will be generated, if trap recipients are configured through the Configure SNMP dialog box. An unresolved congestion event occurs when the rerouting algorithm cannot find a path for rerouting data flow and relieving congestion on an ISL. - Back Pressure. Click this check box to display a checkmark and enable this option. If enabled, a back pressure entry will be made to the Event Log and an SNMP trap will be generated if trap recipients are configured through the Configure SNMP dialog box. A back pressure event occurs when the percentage of time the ISL has no available BB_Credit exceeds the Low BB_Credit threshold. A separate event also occurs when the back pressure condition ends. 5. Set the Low BB_Credit Threshold. Note: Using default settings for Low BB_Credit Threshold should work well in most cases. This step is not required. Director Product Manager User Guide 201
