What's the best reason for using managed switches? I maintain a small network of 29 desktops, 13 printers, wireless access points spanning 2 20,000ft warehouses and of course servers to run the system. We acquired 4 cisco catalyst express 500 managed switches (probably because they where the cheapest managed switch at the time, I wasn't the sys admin then) and they have been a pain in the you know what to maintain. I since have had to replace one and I got a cisco sg102 unmanaged plugged it in and bam it works no fuss I get 48 Mbps and I didn't have to spend anytime setting it up.
So what am I missing? I have to say that I've been doing this for 9 years and I have no cert training of any kind. I graduated with an A.S. in computer science and went straight to work. I don't spend anytime at home reading about this stuff, only read at work when I can - not a lot obviously. So I know I am not completely caught up on everything. Hence the question. Thanks for any responses!
