Description Description 

of the RMON event log 

 

The above output indicates that two logs are generated due to event 1: 

z 

Log 1.1 is generated from alarm entry 1, because the sampled value (0) of the alarm entry is lower 

than the falling threshold (100). The sampling type is absolute. 

z 

Log 1.1 is generated from prialarm entry 1, because the sampled value (0) of the prialarm entry is 

lower than the falling threshold (100). The sampling type is absolute. 

display rmon history [ interface-type interface-number | unit unit-number ] 

Any view 

interface-type: Interface type. 

interface-number: Interface number. 

unit unit-number: Specifies a unit number. 

Use the display rmon history command to display the RMON history information about a specified 

port. The information about the latest sample, including bandwidth utilization, the number of errors, the 

total number of packets, and so on, is also displayed. 

After a history entry is created on a port, the system collects statistics of the port at a certain interval, 

and saves the information in the etherHistoryEntry table. You can use the command to display the 

records saved in the table. 

If you do not provide the interface-type interface-number or  unit-number argument, this command 

displays the RMON history information about all the ports/units.
