I am having trouble graphing the right memory usage in MRTG.  Why does the
graph show current used 356.8MB of memory  Please help.  I provided:  My
"sho version", the graph display, and my config information.

the information lines state the following:

Max Used 357.0 Mb/s (79.5%) Average Used 346.9 Mb/s (77.3%) Current Used
356.8 Mb/s (79.5%) 
Max Free 118.3 Mb/s (26.3%) Average Free 102.0 Mb/s (22.7%) Current Free
92.1 Mb/s (20.5%) 

In my cfg file I have:

MaxBytes[MY_ROUTER01.mem]: 56113080

When I do a "sho version"  I get the following:

MY_ROUTER01#sh version
