Cisco catalyst 3850 switch, a new industry’s first fixed, stackable GE switch that Cisco released earlier this year. As we known, Cisco has a big family of catalyst switches that meet the different sizes of offices and organizations, including Cisco 2960, Cisco 3560, 3750, 4500 and 6500 switches. Cisco switch users like to compare the new Cisco 3850 with Cisco 3750 series. Which series is more suitable for your business? Here let’s have a discussion, also list some main points to know them well.
Some Questions about Cisco 3750 vs. Catalyst 3850 series
“Hi, we are in the process of replacing an order for Cisco switch and we got an upgrade offer without extra cost from 3750 V2 to 3850. Is there a technical comparison between the two models? Our big concern is about stacking, how many is supported by 3750 v2 ( I think 9) and how many for 3850 ( Is it 4)?”
“Hi all, anyone can tell some similarities and differences between the new 3850 series switches and 3750X series.”
The two above typical questions we got from the Cisco learning community, also there are many similar questions of Cisco 3750 and 3850 series comparison.
