[AusNOG] Cisco 3750-X vs 3850

Thu May 22 17:14:40 EST 2014

We are in the same position now, all new switches we buy are 3850s

Just fyi, the documentation says that the 3850 only stacks 4 at a time but that has been fixed in new versions, stack power I believe is still limited to 4 that obviously that is less critical.

Another plus, they are slightly less deep than the 3750x as well which can be handy to know...

Cheers,
Ayden

+2 to Brad

We only buy 3750X if we are growing an old stack that hasn't reached it's upgrade date

Otherwise 3850's are an amazing choice

If/when you go down WLC Path you can have a 5508 control the 3850 etc in a mesh controller architecture

Cheers
