I am just planning to upgrade the IOS on our 2960 Series switches with currently we have 12.x but planning to 15.x.
I have tested on our test environment and found one issue that related to memory utilization as on 12.x IOS they are using very little memory but when tested on 15.x they are using a lots of memory and little free available.
I have few questions.
1. Why this new IOS 15.x utilizing huge memory? and little memory available.
2. What will be happen if the switch is running fully loaded (i.e. Processor 80-90% utilization) then i think the available memory will also be fully utilized?
3. Can we upgrade the memory module in the switch as i don't see any memory module in 2960 so where are the memory module in switches as these memory built-in in the Processor?
