Cisco Cisco Email Security Appliance C160 Mode D'Emploi

To see the available traps and threshold values on your appliance, run the 

snmpconfig

 command from 

the command-line interface. 

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 an appliance with 
multiple fans or power supplies and the appliance will continue to operate. 

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 email security appliance). After the 
condition has been met, the SNMP agent then forms an SNMP packet and sends it to the host running 
the SNMP management console software. 

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.

In the following example, the 

snmpconfig

 command is used on a C690 hardware appliance to enable 

SNMP on the “PublicNet” interface on port 161. The community string 

public

 is entered for GET 

requests from versions 1 and 2.
