I'm building a CCNA/CCNAS lab, I can get my hands on some cheap 2948 level 3 switches.

I was wondering if they also can be used for the CCNAS labs as I always see the 2950 mentioned for these. Are there any features that the 2950 has that the 2948 doesn't have?

2950's are painted in light Cisco blue. 2948's aren't. Go ahead and use the 2948.

To be less tongue-in-cheek, you'll be able to do anything (and then a bit more on L3) with the 2948 than the 2950. I can't think of a reason to not use them. I'd throw in one 2950 just to have the variety and catch students who somehow get lost in the L2/L3 separation.

2948G-L3s are extremely old (over 10 years) and extremely feature limited. They don't support a lot of things you would expect, and are, hardware wise, a mismash of really old IOS switches with the routing "brains" from a 8500 ATM switch router option card. When they have hardware failures, they can even send out syslogs about ATM cell failures. I'd look at 2600s instead - at least you can get code for them that will support most routing protocols and features correctly.

Simply put, no.

The 2948 doesn't support IOS, only CatOS, so this isn't going to help at all in CCNA study because the commands can be very different. I happen to have a 2948 beside me - there is no IOS upgrade for them.

I would suggest you use the 2950s for CCNA and see if you can get a cheap 26x1 router from eBay. Make sure it's an x1 as 26x0 has only one Ethernet port.
