I'm considering a switch purchase and every reference I've seen refers to the Catalyst 1900. All of these on Ebay seem to have 10 meg throughput on most if not all ports. Isn't 100 meg the defacto standard these days? Is there a particular flavor of 1900 that supports 10 and 100? Are there particular designations that should be selected prior to purchase? Are there any other caveats that should be considered prior to purchasing a switch?
 
If you look at the product guides on Cisco site or any of the CCNA guide books, you will learn that the 1900 has 12 to 24 10Mbps ports and 2 10/100 ports for the switch cross connect or connection to the network. The 1900 is a very capable switch for a relatively cheap price for a small network. There are two version of the 1900. The older has a DB9 CON port.. dont want this..it can not be upgraded to the newest code with VLAN support. The newer ones use the RJ45 and are about 1/2 the size of the older ones.

The 2900 is 12 to 24 10/100 ports and is the work horse switch. It's been replaced by the 2950. They cost a bit more then the 1900 but are much more flexible. Again, a couple of versions and you want the one with 8 meg of memory (if my memory is correct) to put the enterprise code on it for full VLAN support and other fun things. The unwanted 2900s are 4 meg of memory.

The two switches use different interfaces so if this switch for certification, you need to decide how important the interface is. The official CCNA testing specs out the 1900. CCNP works hard with the 2900(IOS based) and 5000 (set based)

you may want to check and check the article with "Anna Nicole Smith". You'll surely understand the concept of the 1900 switch. This is a no joking matter bro. RouterGod.Com has that style of explaining things the celebrity way. hehe! Even Alicia Silverstone has a CCNA. huh!
Check out the site bro! You'll surely learn it while enjoying it at the same time.
 
MikeS: Thank you for the comments. This is exactly the info for which I was querying. I haven't yet determined how to identify the different models, but will endeavor to do so.

ecafracs: I just recently visited and was enlightened by Alicia Silverstone on ISDN. I have reviewed Anna Nicole's advise and determined that I definitely need the enterprise version of the switch. One question that occurs: What is the difference between 100BaseT and FastEthernet. Hasn't 100BaseT evolved as the defacto standard? What differences need to be learned for the CCNA exam?

 
100 baseT is fastethernet bro. 802.3u.
100baseT is gigabit ethernet 802.3z.
 
yeah sorry forgot the extra zero on gigabit ethernet - 1000baseT - 802.3z -gigabit ethernet.
