Usage Guidelines Using the snmp trigger global configuration command, you can define additional SNMP traps for other
MIB objects of interest to your particular configuration. You can select any MIB object from any of the
support MIBs for your trap. The trap can be triggered based on a variety of tests:
• absent—A specified MIB object that was present at the last sampling is no longer present as of the
current sampling.
• equal—The value of the specified MIB object is equal to the specified threshold.
• falling—The value of the specified MIB object has fallen below the specified threshold value. After
a trap is generated against this condition, another trap for this same condition is not generated until
the sampled MIB object value rises above the threshold value and then falls below the falling
threshold value again.
• greater-than—The value of the specified MIB object is greater than the specified threshold value.
• less-than—The value of the specified MIB object is less than the specified threshold value.
• on-change—The value of the specified MIB object has changed since the last sampling.
• present—A specified MIB object is present as of the current sampling that was not present at the
previous sampling.
• rising—The value of the specified MIB object has risen above the specified threshold. After a trap
is generated against this condition, another trap for this same condition is not generated until the
sampled MIB object value falls below the threshold value and then rises above the rising threshold
value again.
The threshold value can be based on an absolute sample type or on a delta sample type. An absolute
sample type is one in which the test is evaluated against a fixed integer value between zero and
4294967295. A delta sample type is one in which the test is evaluated against the change in the MIB
object value between the current sampling and the previous sampling.
After you configure SNMP traps, you must use the snmp-server enable traps event global
configuration command for the event traps you just created to be generated. Also, to preserve SNMP trap
configuration across a system reboot, you must configure event persistence using the snmp mib persist
event global configuration command, and save the MIB data using the write mib-data EXEC command.
