Processor and IO memory

Whats the difference between processor and IO memory?

Would 90% of Processor memory used be a problem on a Cisco 1601.

Re: Processor and IO memory

Processor memory holds the image and is used for running processes, while io memory is used by the interfaces to hold packets in memory prior to switching to appropriate interface , A sh mem will show you how much memory is being used

>sh mem

Head Total(b) Used(b) Free(b) Lowest(b) Largest(b)

Processor 61C57420 70945760 5155608 65790152 65614448 65737592

I/O 6000000 33554432 1864124 31690308 31652000 31653180

When you see the largest & free column fall to a small amount you should be concerned . in the above output there is 65MB free in the largest column ,

On a 1600 you may be able to use the memory-size iomem xx command to change the amount of io mem on a % basis that is allocated , you must reload the box for this to take affect
