You can figure out the memory/flash requirements from the IOS upgrade planner easily enough: http://www.cisco.com/cgi-bin/Software/Iosplanner/Planner-tool/iosplanner .cgi?
Your memory requirements are a mix of major revision and feature set. Since you've got 40/8, looks like latest 12.2.46a with IP only would be latest you can fit on that, or instead 12.1 IP/FW/IDS if you want NAT and firewall features. If you wanted the latest and most feature filled version, it would be 12.3.25 with a requirement of 64MB RAM And 32MB flash (although the image is only 17MB so it would fit on a 20MB flash) If you're unfamilar with the feature sets, using the feature navigator helps compare sets and figure out what features are unique to each: http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Brandon Sent: Wednesday, February 06, 2008 22:32 To: [email protected] Subject: [c-nsp] Best Cisco 3620 IOS I've got a Cisco 3620 here that I've been playing around with. I'm wondering if anyone knows the best version of IOS that would run on it. I understand that you need to have a minimum amount of memory to run some version of IOS and I'm willing to buy some more RAM for this machine if that's what I need to do. I apologize if this question seems out of place or really simple. I'm young and this is my first go at Cisco routers.
