Product overview
WS-C3850-12XS-E is a 12-port 10G SFP+ Catalyst 3850 aggregation switch with an IP Services feature set. The listing shows C3850-NM-4-10G as the uplink module, 320 Gbps, 227.28 Mpps, Non-PoE, and PWR-C1-350WAC.
Use it for fiber aggregation refreshes that must stay on 3850 optics and stack kits. New greenfield designs should also evaluate Catalyst 9300 fiber options.
