Dell C1048P Port Extender Networking Configuration Guide for the C9000 Series - Page 954

NOTE: A network management system (NMS) should be ready to interpret a down interface and plot the interface performance graph accordingly. • Line Card Down - The same as Interface Down (see previous). • Chassis Down - When a chassis goes down, all sampled data is lost. But the RMON configurations are saved in the configuration file. The sampling process continues after the chassis returns to operation. • Platform Adaptation - RMON supports all Dell Networking chassis and all Dell Networking Ethernet interfaces. Setting the RMON Alarm To set an alarm on any MIB object, use the rmon alarm or rmon hc-alarm command in GLOBAL CONFIGURATION mode. • Set an alarm on any MIB object. CONFIGURATION mode [no] rmon alarm number variable interval {delta | absolute} rising-threshold [value event-number] falling-threshold value event-number [owner string] OR [no] rmon hc-alarm number variable interval {delta | absolute} rising-threshold value event-number falling-threshold value event-number [owner string] Configure the alarm using the following optional parameters: • number: alarm number, an integer from 1 to 65,535, the value must be unique in the RMON Alarm Table. • variable: the MIB object to monitor - the variable must be in SNMP OID format; for example, 1.3.6.1.2.1.1.3. The object type must be a 32-bit integer for the rmon alarm command and 64 bits for the rmon hc-alarm command. • interval: time in seconds the alarm monitors the MIB variable, the value must be between 1 to 3,600. • delta: tests the change between MIB variables, this option is the alarmSampleType in the RMON Alarm table. • absolute: tests each MIB variable directly, this option is the alarmSampleType in the RMON Alarm table. • rising-threshold value: value at which the rising-threshold alarm is triggered or reset. For the rmon alarm command, this setting is a 32-bits value, for the rmon hc-alarm command, this setting is a 64-bits value. • event-number: event number to trigger when the rising threshold exceeds its limit. This value is identical to the alarmRisingEventIndex in the alarmTable of the RMON MIB. If there is no corresponding rising-threshold event, the value should be zero. • falling-threshold value: value at which the falling-threshold alarm is triggered or reset. For the rmon alarm command, this setting is a 32-bits value, for the rmon hc-alarm command this setting is a 64 bits value. • event-number: event number to trigger when the falling threshold exceeds its limit. This value is identical to the alarmFallingEventIndex in the alarmTable of the RMON MIB. If there is no corresponding falling-threshold event, the value should be zero. Remote Monitoring (RMON) 954
