WS-C3850-12XS-E is a managed Layer 3 fiber access and aggregation switch with twelve fixed 1G/10G SFP+ ports, IP Services software, and a 1U rack-mount chassis. Dedicated uplink expansion uses an empty modular bay that accepts C3850-NM-4-10G, adding four 1G/10G interfaces when ordered separately. Unlike a copper access switch, this non-PoE configuration connects fiber links rather than supplying endpoint power. The Catalyst 3850 Series serves enterprise campus access and branch aggregation, including traffic collected from smaller access switches. Compared with the discontinued WS-C3850-12XS-S, the IP Services model enables full enterprise routing rather than the IP Base feature set. That distinction matters when the purchase order specifies advanced routing without a later feature-tier upgrade.
WS-C3850-12XS-E price for new stock is $2,806.65. WS-C3850-12XS-E refurb price is $409.50. WS-C3850-12XS-E is in stock and available for free next-day delivery. (terms applied)

320 Gbps switching capacity and 227.28 Mpps forwarding provide performance limits for sizing fiber traffic. OSPF, EIGRP, BGPv4, and IS-ISv4 support full IPv4 routing; OSPFv3 and EIGRPv6 cover IPv6, while PIM-SM, PIM-DM, and SSM provide multicast routing. Cisco Catalyst 3850 forwarding uses the UADP ASIC, with MACsec supporting AES-256 encryption on SFP+ models. WS-C3850-12XS-E carries 4 GB of DRAM and 4 GB of flash for software execution and image storage. The 32000-entry MAC table supports Layer 2 address learning, and the 24000-entry IPv4 total includes ARP entries plus learned routes rather than learned routes alone. Flexible NetFlow records traffic for flow analysis, while MSTP and PVRST+ provide spanning-tree control. Detailed CLI configuration and Cisco Prime Infrastructure support administration and monitoring; SSH requires the cryptographic software image. 112.7W at full test traffic with C3850-NM-4-10G provides a power-planning reference for that module-equipped configuration, not the power supply's output rating.

In a hyper-converged data center environment, the Cisco Catalyst WS-C3850-12XS-E 12-port 10G fiber switch IP Services aggregates SFP+ links from virtualized server clusters and leverages IOS XE dynamic routing (OSPF/EIGRP) to optimize east-west traffic. Benefit: delivers ultra-low latency, simplifies network topology, and accelerates VM migrations by up to 30% while maintaining carrier-grade reliability.
On a multi-building enterprise campus, the WS-C3850-12XS-E consolidates 1G/10G fiber uplinks from distribution closets and uses Cisco IOS XE IP Services to enforce QoS for voice, video and data streams. Benefit: ensures sub-second failover, improves VoIP call clarity, and scales bandwidth seamlessly to support high-definition video conferencing and digital signage.
At a regional branch office, the Catalyst 3850 12-port 10G fiber switch IP Services terminates dual 10Gbps MPLS and Internet circuits, running BGP for automatic route failover and traffic engineering. Benefit: achieves sub-50 ms WAN resilience, consolidates routing and switching into one platform, and reduces capital and operational expenses by eliminating standalone edge routers.
When smaller access switches feed an existing branch aggregation point, WS-C3850-12XS-E can consolidate their fiber connections. Jumbo frames reach 9198 bytes, so frame-size requirements need an end-to-end check rather than a local setting alone. Specify the required optics and validate the link MTU before the purchase order.
When a routed edge requires separate tenant routing contexts, IP Services provides VRF-Lite on WS-C3850-12XS-E. The hardware supports 1000 switched virtual interfaces, but interface scale does not replace a routing design review. Check addressing, route allocation, and the intended virtual routing configuration before specifying the unit.
When staging a replacement away from its production network, WS-C3850-12XS-E can be configured locally through RJ-45 or USB console access. An active USB console disables the RJ-45 console connection, so parallel console sessions are not available. Specify the console connection and check workstation compatibility before submitting the purchase order.
PoE power for attached endpoints
WS-C3850-12XS-E has fiber data interfaces rather than powered copper access ports. Directly attached phones and access points require separate endpoint power; this model cannot provide PoE.
40G uplinks to distribution
WS-C3850-12XS-E accepts C3850-NM-4-10G, not C3850-NM-2-40G. A requirement for 40G distribution links exceeds the removable uplink options supported by this particular model.
Cisco service beyond April 2027
Cisco service for WS-C3850-12XS-E ends April 30 2027, excluding a longer Cisco-backed service horizon. Evaluate the current C9300X-12Y replacement for a refresh instead.

WS-C3850-12XS-E identifies a Catalyst 3850 switch with twelve SFP+ Ethernet ports and IP Services. WS-C3850 names the switch family, 12 gives the fixed port count, XS identifies the SFP+ configuration, and E selects IP Services. The configuration includes a 350W PWR-C1-350WAC supply in a 1U chassis.
WS-C3850-12XS-E is managed through the web UI, CLI over console, SSH or Telnet, Cisco Network Assistant, Cisco Prime Infrastructure, and SNMPv3. RJ-45 and USB console connections support local setup. SSH and cryptographic SNMPv3 require the cryptographic software image, while the Ethernet management port provides a separate network-management connection.
C3850-NM-4-10G is the supported uplink module for WS-C3850-12XS-E and adds four 1G/10G SFP+ interfaces. The base model ships with an empty network module bay, so those additional ports are not installed as standard. C3850-NM-4-1G, C3850-NM-2-10G, C3850-NM-8-10G, and C3850-NM-2-40G are not supported on this model.
StackWise-480 stacks nine WS-C3850-12XS-E members with 480 Gbps stack bandwidth. The standard cable is STACK-T1-50CM; longer spares are STACK-T1-1M= and STACK-T1-3M=. Match the members' feature sets and plan a complete ring; incomplete cabling halves available stack bandwidth and removes redundant connections.
WS-C3850-12XS-E provides Layer 3 routing under IP Services, including full OSPF, EIGRP, BGPv4, and IS-ISv4. IPv6 routing includes OSPFv3 and EIGRPv6; multicast routing includes PIM-SM, PIM-DM, and SSM. VRF-Lite supports separate routing contexts with overlapping addresses. Match these features to the intended routing design rather than assuming IP Base provides the same advanced protocol set.
WS-C3850-12XS-E includes IP Services; optional Cisco DNA Essentials and Cisco DNA Advantage add-ons have three-year minimum terms, with five-year terms also offered. Cisco Smart Software Manager handles Smart Accounts. Subscription expiration requires renewal or deactivation and reload to retain base-license operation; an ORM hardware order does not require those optional add-ons.
No, WS-C3850-12XS-E ships with one PWR-C1-350WAC and an empty second power-supply bay, so redundant internal power is optional. Specify PWR-C1-350WAC= if a matching spare or second supply is required. The installed supply accepts 100-240V AC; its 350W output rating is not the switch's operating draw.
WS-C3850-12XS-E is discontinued: sales ended April 30 2022 and Cisco support ends April 30 2027. C9300X-12Y is the current replacement. New service attachment ended April 30 2023, and service renewals ended July 29 2026. Existing eligible contracts continue only until the final support date; check coverage before reusing hardware.
New sealed and certified refurbished WS-C3850-12XS-E units carry ORM warranties up to 3-year extended and 1 year, respectively. Every condition has 30-day returns; terms apply. Cisco's Enhanced Limited Lifetime Warranty is for the original customer, subject to eligibility, and Cisco service ends April 30 2027.
WS-C3850-12XS-E includes IP Services, while WS-C3850-12XS-S includes IP Base. Both are discontinued twelve-port SFP+ models. The IP Services version suits full enterprise routing requirements; the IP Base version suits routed-access requirements within its feature set. Match the image to the existing configuration when sourcing a replacement.
WS-C3850-24P-E supplies PoE+ on twenty-four Gigabit copper ports, while WS-C3850-12XS-E supplies no endpoint power through its twelve fiber interfaces. Both models are discontinued. The fiber model addresses aggregation links; the PoE+ configuration addresses powered copper endpoints, so their port media and counts prevent a like-for-like substitution.
C9300X-12Y supports twelve 1G/10G/25G SFP28 ports, whereas WS-C3850-12XS-E has twelve 1G/10G SFP+ ports. The discontinued 3850 model fits an existing 10G fiber installation; C9300X-12Y is the current migration option for a refresh requiring native 25G connectivity rather than retaining the older port-speed ceiling.
WS-C3850-12XS-E reaches 112.7W in the full-traffic test configuration with C3850-NM-4-10G. That configuration uses 115V AC at 60 Hz and IMIX traffic; idle draw is 109W. Treat these as configuration-specific planning figures rather than replacing them with the PWR-C1-350WAC supply's 350W rating.
WS-C3850-12XS-E is a full-width, 1U rack-mount switch measuring 44.5 mm high, 445 mm wide, and 450 mm deep. The 5.8 kg chassis weight includes one power supply and fans but excludes the optional uplink module. Reserve rear access for power and stacking connections when planning rack placement.
