[AusNOG] Cisco 3750-X vs 3850

[Lindsay Hill]

If you haven't already seen it, there was a good session on the 3850 at
this week's Cisco Live

3850 and 3650 Switching Architecture:
https://www.ciscolive.com/online/connect/sessionDetail.ww?SESSION_ID=78471&backBtn=true

(didn't attend in person, just read through the presentation)

I still can't figure out what the point of the new 3850 SFP model is
though. How many people are deploying new fibre aggregation switches, but
only at 1G? I must be missing something.
