Hi Experts,

I am new to CISCO ... I am very very confused with the various IOS versions ...

I want to practive my CCNA and then CCNP labs ... what version of IOS best suited for this purpose?

For example:

IP Plus c2600-is-mz.123-16a, c2600-is-mz.122-32
Enterprise Plus: c2600-js-mz.122-32, c2600-js-mz.121-27b, c2600-js-mz.120-2.T

What are the differrencees between IP Plus / Enterprise Basic/ Enterprise Plus etc?
Also c2600-js-mz.120-2.T, c2600-js-mz.121-27b (What these b or T means at the end?)

Can you please post any nice easy to use website / link to get idea about these various IOS version and their differrences etc?

Many Thanks in advance
