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, 
absolute ratio or change 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: Creator of this entry. Length of the character string ranges from 1 to 
127.

Use the rmon prialarm command to add an entry to the extended RMON alarm 
table.

Use the undo rmon prialarm command to cancel an entry from the extended 
RMON alarm table.

The number of instances can be created in the table depends on the hardware 
resource of the product.

n 

You can define up to 50 prialarm entries.

The system takes these actions on the extended alarm entries you defined:

■

Sampling the alarm variables in the defined extended alarm formula at a 
specified time interval.

■

Calculating the sample value using the defined extended alarm formula.

■

Comparing the sample values against the predefined threshold and take 
further actions (see Table 135).

Table 135   Handling extended alarm entries

The calculated sample value is greater than 
the upper limit threshold-value1. 

Triggers the defined event event-entry1 

The calculated sample value is less than the 
lower limit threshold-value2. 

Triggers the defined event event-entry2
