So, when buying, you have a choice: buy a Standard model or buy an Enhanced model.

LATEST IOS VERSION FOR CISCO 2950 SWITCH SOFTWARE

The choice of whether a 2950 is a Standard or Enhanced switch is based on the model, not based on the software installed. It's just hard to tell from what documentation I've been able to find. So, while differences do still exist between the Standard and Enhanced switches, the differences at later code versions is not a lot, and they may well be the same. (The EI and SI refer to Enhanced Image and Standard Image, respectively.) There's more background on this page if you're interested. Today, per the Cisco feature navigator, if you loaded the most recent IOS version and feature sets, some IOS names like "C2950 EI and SI." are listed, implying one code build that would run on either an SI or EI switch. Over time, the Cisco feature navigator reflected these changes. However, it appears that over time, Cisco started supporting more and more of the enhanced features in the Standard 2950's.

You had to pick standard or enhanced when you ordered the switch, and you could not later field upgrade the software to make it an enhanced switch. The Enhanced models originally had more features. Cisco originally offered two main 2950 options: standard models and enhanced models. The IOS support picture for 2960's is frankly a bit fuzzy, and that fuzziness does matter to what you buy. In short, it's a good compromise of price versus function. The commands, and the show command output, tends to more closely match the syntax and output expected on the newer and still-sold-as-new 2960's, whereas the even older (but cheaper) 2900XLs have some command and output differences. Our pricing tests show these in the $75-$100 range over the previous month. These models have been in a sweet spot of having relatively good and recent feature and command support, while being old enough to have a good price in the used market.

The 2950 series was popularly sold as new in the early to mid 2000's, but is now in End-of-Sale status. 2) 2950 Series Backgroundīefore diving into the CCNP discussion, we need to discuss a little background on 2950's. So, be ready to ask before you buy, and do a little searching around Cisco's feature navigator ( to validate what's supposed to be supported. Click here to see the CCNP features versus these IOS versions on various switch models.įinally, most of the EBay listing for switches do not mention that IOS version, at least in my experience. At the same time, 12.2SE is supported on the 29 series, but not so new as to make me think that you wouldn't find many switches with this version on the used market. Why? The latest version for 2950's is 12.1EA. To give us some context for discussion and reference, I've picked a couple of IOS versions on which to focus for a CCNP comparison: 12.1EA and 12.2SE. So, when researching switch IOS versions and feature sets, you can't just search the IOS version/feature set alone - you must do so in the context of each switch model series. While the equivalent does happen with routers in some cases, the danger appears much greater with switches. A given software version on one switch model series may not have the same features as the same version on another switch. Understanding switch software poses one of the bigger challenges when considering which used switches to buy. (Sorry for the length of this post - I'm trying to get the series wrapped before I take off for some upcoming vacation.) 1) Switch IOS Considerations

I'll start with a couple of background topics, and then compare 4 model series: 2950, 3550, 2960, and 2900XL. Today I'll look at the main options and discuss the pros and cons. Is there a single best switch model series to buy to build a CCNP lab in 2010? I think the clear winner for a CCNA lab would have to be the 2950 series switch, but the choice is not as clear for CCNP.
