SNMP Monitoring
Hardware Objects
Hardware sensors conforming to the Intelligent Platform Management Interface Specification (IPMI)
report temperature, fan speed, and power supply status.
report temperature, fan speed, and power supply status.
The number displayed is the number of instances of that object that can be monitored. For example, you
can query the RPMs for 4 fans in the S350 appliance.

Hardware Traps
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). Temperatures within 10 per cent of the critical value may be a cause for
concern.

Note
Failure condition alarm traps represent a critical failure of the individual component, but may not cause
a total system failure.
a total system failure.
SNMP Traps
SNMP provides the ability to send traps, or notifications, to advise an administration application 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 Cisco Web Security Appliance 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, the trap target of
