2-4z The rmon alarm and rmon prialarm commands take effect on existing nodes only.z For each port, only one RMON statistics entry can be created. That is, if an RMONstatistics entry is already created for a given port, you will fail to create anotherstatistics entry with a different index for the same port.Displaying RMONTo do… Use the command… RemarksDisplay RMON statistics display rmon statistics [ interface-typeinterface-number | unit unit-number ]Display RMON historyinformationdisplay rmon history [ interface-typeinterface-number | unit unit-number ]Display RMON alarminformation display rmon alarm [ entry-number ]Display extended RMON alarminformationdisplay rmon prialarm[ prialarm-entry-number ]Display RMON events display rmon event [ event-entry ]Display RMON event logs display rmon eventlog [ event-entry ]Available inany view.RMON Configuration ExampleNetwork requirementsz The switch to be tested is connected to a remote NMS through the Internet. Ensure thatthe SNMP agents are correctly configured before performing RMON configuration.z Create an entry in the extended alarm table to monitor the information of statistics onthe Ethernet port, if the change rate of which exceeds the set threshold, the alarmevents will be triggered.Network diagramFigure 2-1 Network diagram for RMON configurationConfiguration procedures# Add the statistics entry numbered 1 to take statistics on GigabitEthernet 1/0/1. system-view[Sysname] interface GigabitEthernet 1/0/1[Sysname-GigabitEthernet1/0/1] rmon statistics 1
