strings. The CLI online help system displays the value range as character strings of 1 to 512
characters. If the threshold value contains spaces, you must enclose the value in quotation marks ("
").
interval interval: Specifies the sampling interval in the range of 1 to 4294967295, in seconds. The
default value is 300.
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.
EAA executes an SNMP event 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.

event snmp-notification
Use event snmp-notification to configure an SNMP-Notification event for a CLI-defined policy.
Use undo event to remove the event in a CLI-defined policy.
