[AusNOG] Cisco 3750-X vs 3850

[Damian Guppy]

+1 to brads comments. We have moved over to the 3850's long ago. Not
sure why Skeeve brought up wireless as the 3750x also had a line that
did the wireless stuff (just not as well).

Of note is the 3850 is based on ciscos new IOS XE platform and is not
really an updated version of the 3750 but a whole new switching
platform.

A 3850 is hardly just a 3750X, Skeeve.

The stacking architecture on the 3850-series switches has been
radically overhauled when compared to the 3750X. It has vastly
superior stack bandwidth (480Gbps compared to 64Gbps) and features SSO
across the stack - so if you cable it correctly and a switch dies,
another one takes over and the stack keeps running without a drop.

3850s have bigger flash, more queues per port, QoS using MQC and not
MLS, and support NetFlow!

IMHO - if you're buying new switches, there is no case where you would
buy a 3750X over a 3850 unless you're trying to expand an existing
stack.

Regards,
-Brad.

I think if you don't use wireless in the deployment context, then
these are just 3750X's.

Hi All,

We have an environment with a large quantity of 3750-Xs (several PoE
and non-PoE variants) is use as access switches. For a separate server
access segement I've now had quotes for 3850s. The literature looks
attractive, not that we need the extra 10GE capacity or wlan
controller yet but I'm wondering if it is worthwhile starting down the
3850 path.

Has anyone had some experience with these in production as yet and any
shortfalls/issues I should be aware of? Strictly ip-base at present.

Cheers,
Peter
