1-3z Log-Trap: Logging event information in the event log table and sending a trap to the NMS.z None: No action.Configuring RMONConfiguration Task ListConfiguring the RMON statistics functionRMON statistics function can be implemented by either the statistics group or the history group, but theobjects of the statistics are different. You can choose to configure a statistics group or a history groupaccordingly.z A statistics object of the statistics group is a variable defined in the Ethernet statistics table, and therecorded content is a cumulative sum of the variable from the time the statistics entry is created tothe current time. Perform the tasks in Table 1-1 to configure RMON Ethernet statistics function.z A statistics object of the history group is the variable defined in the history record table, and therecorded content is a cumulative sum of the variable in each period. Perform the tasks in Table 1-2to configure RMON history statistics function.Table 1-1 RMON statistics group configuration task listTask RemarksConfiguring a StatisticsEntryRequiredYou can create up to 100 statistics entries in a statistics table.After a statistics entry is created on an interface, the system collectsstatistics on various traffic information on the interface. It providesstatistics about network collisions, CRC alignment errors,undersize/oversize packets, broadcasts, multicasts, bytes received,packets received, and so on. The statistics are cleared after the devicereboots.Only one statistics entry can be created on one interface.Table 1-2 RMON history group configuration task listTask RemarksConfiguring a HistoryEntryRequiredYou can create up to 100 history entries in a history table.After an entry is created, the system periodically samples the number ofpackets received/sent on the current interface, and saves the statistics asan instance under the leaf node of the etherHistoryEntry table.When you create an entry, if the value of the specified sampling interval isidentical to that of the existing history entry, the system considers theirconfigurations are the same and the creation fails.
