Hi all, I am interested in purchasing a couple of 3550 switches for my home lab, however, I was just wanting to know what the difference between them and the 3750's?
Also, do the 3550's support NBAR?
Thanks for the information.
Functionality wise, what does the 3750 do that the 3550 can't?
I have heard SRR, NAT and NBAR, but was wanting to know, is there anything else?
The 3750 does not support NAT or NBAR. Of the catalyst switches only the 6500 supports NAT.
The 3750 is simply a more recent switch with greater thoughput although the features are not identical. For a lab the 3550 switches would be fine as you can run most of what you would need to do in a lab. Have a look at the 2 datasheets if you haven't already seen them -
3750s are stackable but 3550s are not.
3750s have higher backplane speed then 3550s
3550s are end-of-life
3750s are more expensive
Overall, for lab use 3550s are more economical then 3560s and 3750s
Here is list of Cisco products that support NBAR:
