Parameter
entry-number: Specifies the entry number, ranging from 1 to 65535.
alarm-var: Specifies the alarm variable, which can be an arithmetic expression of
several integer MIB node instances. The node can be OID in dotted notation.
alarm-des: Specifies the alarm description with a length ranging from 0 to
0-127;
sampling-timer: Sets the sampling interval, ranging from 10 to 65535 and
measured in seconds.
delta | absolute | changeratio: Specifies the sampling type as delta ratio or
absolute ratio.
threshold-value1: Rising threshold value, specified with a number greater than
0.
event-entry1: Corresponding event number to the upper limit threshold value,
ranging from 0 to 65535.
threshold-value2: Falling threshold value, specified with a number greater than
0.
event-entry2: Event number corresponding to the falling threshold, ranging
from 0 to 65535.
forever | cycle cycle-period: Specifies the type of the alarm instance line.
cycle-period specifies the functional cycle of the instance.
owner text: Specifies the creator of the line. Length of the character string
ranges from 1 to 127.
Description
Use the rmon prialarm command to add an entry to the extended RMON alarm
table. Use the undo rmon prialarm command to delete an entry from the
