Please log in for more thread options Nobody is going to test on a 1900/2800. They are just too old, and have fallen way off the radar for anybody. A WS-C2950-xx is extremly close to the 2960 in features and configuration. Its only been EOL'd fairly recent (announcement for the general line on Oct 22, 2007), so it hasn't gone down in cost too much on eBay, but what are you talking about fairly cheap? A WS-C2950-24 is going for $230 buy-it-now on eBay. Several auctions start in the $30 range, but I suspect the 24 ports get up closer to higher $1xx range. I saw some of the 12-porters going for $105/$107 auction wins. For a CCNA lab, I'd pick up a WS-C2950-12, which will be close enough to the 2960 in the book for all purposes. You can figure out the rest from here I'm sure. The generation after the 1900/2800 is the 29xx goes for cheaper, but the differences will be greater (not quite as great as the 1900/2800 though). They go for $50 (WS-C2924XL-EN-24). For the extra $50, I'd get the 2950 for your lab work. It'll be alot closer to what you'll be tested on. | |||||||||||||

>differences between the 2950-24 and the 2950-24XL? Umm, 2950-24XL? Did you misquote my part # 2924XL ?? No such thing as a 2950-24XL. The main thing to realize is a 2924XL latest IOS rev is 12.1, and hasn't been updated in ~5 years or so. The newer 2950/2960 run IOS rev 12.2, and have had newer features added over the years. Since the 2950 was just EOL'd, it'll have current version of IOS for it. Many commands behave differently between the two, especially with reguard to VLANs, trunking, supports dynamic trunking, and general management. The 2950/2960's web GUI will be vastly improved over the 2924xl's. Most people that I've seen touch the web GUI for the 2924xl delete it and never bother with it later. I've seen people actually use the one for the 2950/2960 switches.. The QoS support is different (but thats not too surprising, QoS is way different on just about every Cisco switch platform). Otherwise, in terms of being 24-port managable switches, they are comparable in feature set, just ways of doing things are slightly different, especially troubleshooting trunking issues. But the original thread was on certification learning, and since they are testing on the 2960, and you should really learn on hardware released within the last 5 years or so... | |||||||||||||

Quick clarification - While I do believe that the 2960 does run IOS 12.2 (much like the 3550, 3560, and 3750 series), the 2950's only run on IOS 12.1. Also, the 2900xl and 3500xl switches run IOS 12.0 - while it is pretty old by today's standards, the 2900xl's will get you by relatively well if you can't afford the 2950s. Definitely stick to the lower port density switches unless you have a particular need for them. A word of caution though, is that Cisco does differentiate feature-wise between their enterprise and standard image software switches. Without getting into too much detail, you'll generally want the enterprise version of software, however for CCNA level studying I suppose the standard image switches would do what you need for that particular exam. >

Agreed, I've gotten burned by this when trying to implement commands from a 3550 onto a 3560. Had to relearn how to do it on the 3560 and there were some gotchas. regards, Mark Holbrook, CCNP | |||||||||||||

Replaced by the 2900/2600 combo. Today the 2950 or 2960 and 1841 or 2811 are the go, althought later 2600s are still very useful fro CCNA study. Aubrey | |||||||||||||
