Application aborts, errors, and warning messages, may be configured to trigger a trap if the send a
predictable message to the system console. Likewise, kernel warnings and panic messages may be
used to trigger a trap.
In response to a detected text string, the CCM appliance generates a trap to one, or more, SNMP trap
hosts. The trap host, in turn, may be configured to pass the trap information to the appropriate
administrator via email or beeper indications.
The CCM appliance is also configurable to send a trap upon loss of control signals such as carrier
detect from an attached device. Loss of data signals may indicate failure of a power circuit, failure of
a power supply, software anomalies, or cabling problems. Timely indications of these conditions
allow failed units to be restored to normal operational status before business operations are seriously
impacted by the failure.
Although enterprise SNMP managers are shown in the illustration, freeware and entry-level
managers are widely available and offer basic email and beeper notification. The CCM appliance
supports dozens of enterprise traps; a few more are listed below.
