Operation Manual – SNMP-RMONH3C S5500-EI Series Ethernet Switches Chapter 2 RMON Configuration2-5Note:z Two entries with the same configuration cannot be created. If the parameters of anewly created entry are identical to the corresponding parameters of an existingentry, the system considers their configurations the same and the creation fails.Refer to Table 2-1 for the parameters to be compared for different entries.z The system limits the total number of all types of entries. When the total number ofan entry reaches the maximum number of entries that can be created, the creationfails.z When you create an entry in the history table, if the specified buckets numberargument exceeds the history table size supported by the device, the entry will becreated. However, the validated value of the buckets number argumentcorresponding with the entry is the history table size supported by the device.Table 2-1 Restrictions on the configuration of RMONEntry Parameters to be comparedEventEvent description (description string), event type (log, trap,logtrap or none) and community name (trap-community orlog-trapcommunity)History Sampling interval (interval sampling-interval)Statistics Only one statistics entry can be created on an interface.AlarmAlarm variable (alarm-variable), sampling interval(sampling-interval), sampling type (absolute or delta), risingthreshold (threshold-value1) and falling threshold(threshold-value2)Pri-alarmAlarm variable formula (alarm-variable), sampling interval(sampling-interval), sampling type (absolute, changeratioor delta), rising threshold (threshold-value1) and fallingthreshold (threshold-value2)2.3 Displaying and Maintaining RMONTo do… Use the command… RemarksDisplay RMON statistics display rmon statistics[ interface-type interface-number ]Available inany viewDisplay RMON historyinformation and the latesthistory sampling informationdisplay rmon history[ interface-type interface-number ]Available inany viewDisplay RMON alarmconfiguration informationdisplay rmon alarm[ entry-number ]Available inany view
