start-val start-val
: Specifies the start threshold to be compared with the sampled value. The
start-val
argument can be any data type supported by SNMP, including numerals and character
strings. The value range for the start-val argument is a string of 1 to 512 characters. If the
threshold value contains spaces, you must enclose the value in quotation marks (" ").
restart-op op : Specifies the operator for comparing the sampled value with the restart threshold.
The restart threshold is crossed if the comparison result meets the condition. For keywords available
for the
start-op argument, see Table 6 .
restart-op restart-val
: Specifies the restart threshold to be compared with the sampled
value. The
restart-val
argument can be any data type supported by SNMP, including numerals
and character strings. The value range for the
restart-val
argument is a string 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.
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.
