actions (see 
Table 6-7).  
Table 6-7 Handling extended alarm entries 
Item  Handling 
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
 
Example 
# Add an extended alarm entry in the fifth line of the extended alarm table. Perform 
operation on the corresponding variant by means of the formular 
((.1.3.6.1.4.1.43.45.1.6.1.2.1.1.2.1-.1.3.6.1.4.1.43.45.1.6.1.2.1.1.3.1)*100/.1.3.6.1.4.1.
43.45.1.6.1.2.1.1.2.1) to get the port utilization of Gigabit Ethernet interface 1/1/1. 
Monitor the operation results at the sampling interval of 10 seconds. When the variation 
rate exceeds the upper threshold 50, trigger event 1; when the variation rate gets below 
the lower threshold 2, trigger event 2. Set the alarm instance sampling type to “forever”, 
and set the owner of the extended alarm table to “user1”.
