CPU Usage
This field displays what percentage of the Device’s processing ability is currently used. 
When this percentage is close to 100%, the Device is running at full load, and the 
throughput is not going to improve anymore. If you want some applications to have 
more throughput, you should turn off other applications (for example, using QoS; see 
Chapter 9 on page 139
).
Memory Usage
This field displays what percentage of the Device’s memory is currently used. Usually, 
this percentage should not increase much. If memory usage does get close to 100%, the 
Device is probably becoming unstable, and you should restart the device. See 
Section 
39.2 on page 313
, or turn off the device (unplug the power) for a few seconds.
NAT Session 
Usage
This field displays what percentage of the Device supported NAT sessions are currently 
being used.

Account Status
field 
displays
