Cisco Cisco IOS Software Release 12.4(6)T

The following example shows the configuration of a global memory thresholding policy for I/O memory. 
In this example, the policy is given the name “system-global-io”, and the threshold for critical I/O 
memory usage is defined as being usage of over 90 percent of the globally available I/O memory pool 
for 12 consecutive seconds. 

The critical falling threshold is also defined in this example (less than 20 percent of the globally available 
I/O memory pool for 10 seconds or more); however, only the critical rising level will affect when the 
automatic deallocation procedure is triggered.
