Usage guidelines
Use SNMP event monitor policy to monitor value changes of MIB variables.
You can configure only one event for a monitor policy. If the monitor policy already contains an event, the
new event replaces the old event.
An SNMP event occurs to trigger the policy when the monitored MIB variable's value crosses the start
threshold in the following situations:
• The monitored variable's value crosses the start threshold for the first time.
• The monitored variable's value crosses the start threshold each time after it crosses the restart
threshold.
The following is the SNMP event monitor process of EAA:
1. Compares the variable sample with the start threshold at sampling intervals until the start threshold
is crossed.
2. Executes the policy.
3. Compares the variable sample with the restart threshold at sampling intervals until the restart
threshold is crossed.
4. Compares the variable sample with the start threshold at sampling intervals until the start threshold
is crossed.
5. Executes the policy again.
This process cycles for the monitor policy to be executed and re-executed.
Examples
# Configure a CLI-defined policy to get the value of the MIB variable 1.3.6.4.9.9.42.1.2.1.6.4 every five
seconds. Set the start threshold to 1 and the restart threshold to 2. Enable EAA to execute the policy when
the value changes to 1 for the first time. Enable EAA to re-execute the policy if the value changes to 1
each time after the value has changed to 2.
