Hi Kings,

The logging interval sets the time between to log messages:

"There is also an option to configure the rate-limit interval for which log messages are created, that is the interval between the logging of two messages"

Go to the IOS 12.4T, Configuring Control Plane Security, Control Plane logging and search for logging interval

It's basically protection. Suppose a hacker "assumes" that you have logging enabled on a specific access-list, or some other traffic. 
It could then overload the router if it would hit that access-list continuously, and thus making sure that the router is only processing the log messages and doesn't have sufficient time for the other stuff the control plane is supposed to do (arp, routing protocols, etc)

Hi all
 
Can someone please let me know what is "Logging Interval" referring to?
 
This list is from CCIEchecklist

Cisco IOS Software-Based CPU Protection Mechanisms

(Options Drop, Logging Interval, CPU Threshold)

 

Options drop - use ip options drop or named acl with options

CPU Threshold - use "process cpu threshold type total rising 60 interval 30 falling 30 interval 30

Logging Interval - which command?

 

If you have comments on the "options drop" and cpu thresold", please do add it too.

 

With regards

Kings
