rmon event event-entry [ description string ] { log
| trap trap-community | log-trap log-trapcommunity
| none
} [ owner text ]
Optional
Add an alarm entry
rmon alarm entry-number alarm-variable
sampling-time { delta | absolute }
rising_threshold threshold-value1 event-entry1
falling_threshold threshold-value2 event-entry2
[ owner text ]
Optional
Before adding an alarm entry, you
need to use the rmon event
command to define the event to be
referenced by the alarm entry.
Add an extended
alarm entry
rmon prialarm entry-number prialarm-formula
prialarm-des sampling-timer { delta | absolute |
changeratio } rising_threshold threshold-value1
event-entry1 falling_threshold threshold-value2
event-entry2 entrytype { forever | cycle
cycle-period } [ owner text ]
Optional
Before adding an extended alarm
entry, you need to use the rmon

already created for a given port, you will fail to create another statistics entry with a different index
for the same port.
