About DOS SNMP TRAP

What is the difference between following Trap

 

- apSysSipEndptDemUntrustToDeny: Global counter for SIP endpoint demotion from untrusted to deny

 

Any example to make  this trap ?

 

  

- apSysMgmtInetAddrWithReasonDOSTrap: Generated when an IP address is placedon a deny list because of denial-of-service attempts

 

Any example to make  this trap ?

For this trap apSysMgmtInetAddrWithReasonDOSTrap, will system deny "IP" or deny "IP+Port"

 

Thank you
