Caveats Send documentation comments to [email protected] Symptom: RMON alarms that check the percentage-utilization bandwidth threshold may sometimes fail to report accurate values. This issue might occur when an internal SNMP get of the interface utilization fails, which triggers a false-positive RMON alarm that indicates a bandwidth utilization on an interface that is incorrect. Workaround: This issue is resolved. • CSCtl58793 Symptom: The Fabric Manager interface counters screen in the Protocol pull-down menu does not allow the use of the pencil eraser to clear the BBCreditTransitionFromZero counter. Workaround: This issue is resolved. • CSCtl97673 Symptom: When the slow drain port-monitor policy is changed from its default configuration, there is no corresponding line added to the running configuration or the startup configuration. In addition, the slow drain policy activation configuration is lost after a switch reload; it is not lost upon a supervisor switchover. Workaround: This issue is resolved. • CSCtn26967 Symptom: When an FCIP links starts dropping frames due to congestion control, there is no message given to the user. This issue occurs only in NX-OS Release 4.2 and later. Workaround: This issue is resolved. • CSCtn29907 Symptom: When there is an IVR failure, a core file is produced, and a High Availability supervisor switchover occurs. Workaround: This issue is resolved. • CSCtn48728 Symptom: Cisco devices running NX-OS software might send SNMP linkUp/linkDown trap information in an inconsistent order, which can create interoperability issues for third-party NMS applications. Workaround: This issue is resolved. • CSCtn66877 Symptom: On the MDS 9124 switch, information about free memory is not consistent between CLI commands and SNMP. Workaround: This issue is resolved. • CSCtn93079 Symptom: Call Home is not created for a standby supervisor failure. This issue was seen when the standby supervisor failed and was periodically being reset. When the switch was checked, the standby supervisor was in active state or powered on. Workaround: This issue is resolved. • CSCtn95730 Symptom: An upgrade from SAN-OS Release 3.3(4) to Release 4.2(7a) on a Cisco MDS 9124e 24-port Fabric Switch for c-Class BladeSystem is disruptive.
