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.
For the command to take effect, enable SNMP before you execute this command.
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.
Syntax
event snmp-notification oid oid oid-val oid-val op op [ drop ]
undo event
Default
No SNMP-Notification event is configured.

Parameters
oid oid: Specifies the OID of the monitored MIB variable, a string of 1 to 256 characters.
oid-val oid-val: Specifies the threshold to be compared with the sampled value. The oid-val
argument can be any data type supported by SNMP, including numerals and character strings. The
value range for the oid-val argument is a string of 1 to 512 characters. If the threshold value contains
spaces, you must enclose the value in quotation marks (" ").
