I'd like to get some suggestions for a decent test/config switch. Currently I'm using a borrowed 3560 for IOS testing and device pre-configuration. Now the project that the 3560 was purchased for is going forward, and my boss has approved the purchase of a replacement for me. I really don't need as many ports as the 3560 provides, as at any time I don't have more than 2 or 3 devices connected.
We currently run a core of stacked 3750s (which we will be upgrading later this year, possibly to a 6500 series), with distributed branch switches of various models. Ideally, I would like something in a smaller form factor, but which will run the latest versions of IOS, so I can test prior to upgrading our production switches. I was looking at the 2970, but the latest IOS version available for that is 12.1.
