SNMP Monitoring
Status change traps are sent when the status changes. Fan Failure and high
temperature traps are sent every 5 seconds. The other traps are failure condition
alarm traps — they are sent once when the state changes (healthy to failure). It is
a good idea to poll for the hardware status tables and identify possible hardware
failures before they become critical. Temperatures within 10 per cent of the
critical value may be a cause for concern.

Note that failure condition alarm traps represent a critical failure of the individual
component, but may not cause a total system failure. For example, a single fan or
power supply can fail on a S650 appliance and the appliance will continue to
operate.

SNMP Traps
SNMP provides the ability to send traps, or notifications, to advise an
administration application (an SNMP management console, typically) when one
or more conditions have been met. Traps are network packets that contain data
relating to a component of the system sending the trap. Traps are generated when
a condition has been met on the SNMP agent (in this case, the IronPort appliance).
After the condition has been met, the SNMP agent then forms an SNMP packet
and sends it over port 162, the standard SNMP trap port. In the example below,

You can configure SNMP traps (enable or disable specific traps) when you enable
SNMP for an interface. To specify multiple trap targets: when prompted for the
trap target, you may enter up to 10 comma separated IP addresses.
