i had one consultant (protocol analysis expert) who took at look at the health of our network tell me to upgrade the memory in some 3548 switches (and the IOS). btw, this was about 2 1/2 years ago. another guy (CCIE) told me the memory can't be upgraded.
My boss has the report from the first guy. We are having performance problems on a couple of apps and he is blaming the network telling me we should have upgraded the memory (and the IOS). can ram be added (in order to help performance)?
