Advanced> SNMP> Trap Setting

 

When on, the system will generate an SNMP trap upon a host authorization failure. This failure occurs when a host tries to gain access to the 
system but the host’s IP is not in the SNMP host table.   
 
Authentication traps  

o 

Enable  The system will generate a SNMP trap upon a host authorization failure 

o 

Disable  The authentication traps will not be generated 

 
All hosts in community strings with TRAP privileges will be notified when a trap condition occurs.
