Help me to determine actual RAM size in C3750X

Hi Sreejith,

If you need to make precise calculations you need to sum up the "size" values seen in the output of "show region". This total value should more or less match the value that you seen in the output "show version".

The output of "show proc memory sorted" does not involve memory consumed by process which assist IOS image compression/decompression activity and other internal process which are helpful during router/switch bootup.
