Router show processor memory different from show version

Unanswered Question
Apr 12th, 2009


I have a 2801 router. When I use show version, I know that the memory is 128 MB. But, when I use show processor memory command, I found that when the processor and I/O memory total is only 55 MB. So, which one is the right number ? I checked in the website, that 128 MB is the default memory for 2801. So, I believe that 128 MB is the right one. But why show processor memory doesn't say so ? Where are the rest ? Thanks.

I attach the result of three commands :

1. show memory summary

2. show version

3. show proc mem

Show version shows me 128 MB, while command 1 and 3 shows me around 58 MB. It's different.

Believe show processor memory doesn't show allocation for IOS usage of RAM (which would be about 2x it's compressed IOS image size).
