WS-C3850-32XS-E is a Layer 3 fiber aggregation switch with 24 fixed 1G/10G SFP+ interfaces and eight 1G/10G uplink interfaces on the included C3850-NM-8-10G. The complete bundle exposes 32 fiber interfaces; the additional ports sit on a removable module rather than being built into the chassis. IP Services supplies the advanced routing feature set for enterprise access and aggregation connections. This non-PoE model carries data between access switches and other fiber-connected equipment rather than supplying endpoint power. A Rack-Mount 1U chassis places the Catalyst 3850 in a full-width equipment rack, with active cooling rather than a fanless desktop enclosure. The discontinued WS-C3850-32XS-S carries IP Base instead, making its lower software tier the closest sibling distinction.
WS-C3850-32XS-E price for new stock is $7,426.65, a 87.7% saving from the Cisco list price of $60,349.00. WS-C3850-32XS-E refurb price is $2,408.70. WS-C3850-32XS-E is in stock and available for free next-day delivery. (terms applied)

640 Gbps switching capacity provides the forwarding fabric for the fiber connections, while 454.55 Mpps is the packet-forwarding rate to compare against the expected traffic mix. OSPF, EIGRP, BGPv4 and IS-ISv4 provide advanced unicast routing; OSPFv3 and EIGRPv6 cover IPv6, and PIM-SM supports multicast routing. Address scale reaches 32000 MAC entries and 24000 IPv4 routes, including ARP and learned routes rather than learned routes alone. WS-C3850-32XS-E uses 4 GB of DRAM and 4 GB of flash for control software and image storage. StackWise-480 connects nine members with 480 Gbps stacking bandwidth, distinct from standalone switching capacity. The included PWR-C1-715WAC powers the chassis, and a second PWR-C1-715WAC= can be specified for the empty power bay. At 100% test traffic, 205.5W draw provides a reference for electrical planning, not the PWR-C1-715WAC output rating.
WS-C3850-32XS-E is offered new sealed or certified refurbished; refurbished units are inspected and bench-tested for power-on, POST, rated-speed port links, clean boot and optics bay recognition, with firmware verified and configuration wiped to factory default. ORM provides up to a 3-year extended warranty for new units, up to 1 year for certified refurbished units, and 30-day returns on either condition; terms apply. Cisco's Enhanced Limited Lifetime warranty is original-owner-only and capped at five years after discontinuance announcement; Cisco service ends April 30, 2027. Specify condition and quantity on the PO; enterprise and volume orders support PO acceptance, Net-30 for government and RMA with advance replacement across UK, EU, US and MEA.

In a multi-building enterprise campus, the WS-C3850-32XS-E aggregates 802.11ax AP and IP telephony fiber uplinks into a resilient, stackable core. Leveraging Cisco IP Services (advanced QoS, SGT tagging, PIM-SM multicast), it delivers uniform, low-latency voice, video and data. Benefit: scalable 640 Gbps throughput, simplified management and 99.99% uptime.
In modern data center racks, the WS-C3850-32XS-E provides 32×10G SFP+ ports for east-west server aggregation with OSPF, VRRP and VXLAN routing. Dual power supplies and Cisco FlexStack ensure continuous operation. Benefit: reduces latency by 30%, optimizes resource utilization and supports large-scale multi-tenant environments.
At remote branch locations, the WS-C3850-32XS-E consolidates LAN, WAN and DMZ over 10G fiber uplinks, enforcing IPsec VPN, hierarchical QoS and Cisco TrustSec segmentation. Dual-stack IPv4/IPv6 support simplifies migrations. Benefit: accelerates critical applications, secures end-to-end traffic and cuts network hardware footprint by up to 40%.
An aggregation refresh that also expands traffic monitoring needs collector sizing before hardware is ordered. The switch supports 48000 Flexible NetFlow entries, so the planned flow population is a separate sizing input from link count. Specify the collector integration and monitoring scope before the PO.
An existing stack expansion can change power sharing without changing the data-stack membership plan. StackPower directly connects four switches in a power stack, using CAB-SPWR-30CM= or CAB-SPWR-150CM= rather than data-stacking cables. Identify the intended power-sharing or redundancy mode and specify the cable layout before ordering.
A staging order for equipment stored in an unheated area needs a cold-start check before installation testing. The minimum ambient temperature for starting the switch is 0°C, distinct from its operating-temperature range. Define the staging temperature and acceptance procedure, then specify the bench-test expectations before the PO.
Native 25G fiber downlinks
Native SFP+ interfaces stop at 10G. C9300X-24Y is the current migration model with 24 native 25G fiber ports; specify its uplink configuration separately from this 32-interface bundle.
PoE power for connected endpoints
WS-C3850-32XS-E has fiber data interfaces and does not deliver endpoint PoE. Devices needing network-supplied power require a PoE-capable access switch or a separate power source.
Fanless desktop installation
Active cooling and a Rack-Mount 1U chassis rule out a fanless desktop requirement. The hardware uses three C3850-FAN-T1 fans rather than passive cooling.

WS-C3850-32XS-E identifies a Catalyst 3850 IP Services bundle: WS-C3850 names the switch family, 32XS identifies 32 SFP+ interfaces, and E denotes IP Services. The hardware combines 24 fixed interfaces with eight on C3850-NM-8-10G. Use the complete PID when specifying the bundled configuration.
WS-C3850-32XS-E is managed through the Cisco IOS XE CLI using console access, SSH or Telnet, with SNMP monitoring and Cisco Prime Infrastructure integration. Cisco DNA Center provides licensed automation workflows. SSH requires a cryptographic software image; specify the permitted management method and access credentials before staging.
WS-C3850-32XS-E is discontinued, with end of sale on April 30, 2022 and last support on April 30, 2027. Software maintenance ended April 30, 2023. Service-contract renewals closed July 29, 2026, so an order needs existing coverage and entitlement checked rather than assuming a new contract.
ORM Systems offers WS-C3850-32XS-E new sealed or certified refurbished: new warranty is up to a 3-year extended term; refurbished warranty is up to 1 year. Returns are 30 days, terms apply. Cisco's Enhanced Limited Lifetime warranty is original-owner-only, capped at five years after discontinuance announcement; Cisco service ends April 30, 2027.
WS-C3850-32XS-E includes perpetual IP Services; Cisco DNA Essentials, Cisco DNA Advantage and Cisco DNA Premier are separate term-based options starting at three years. Cisco DNA Advantage supports SD-Access, while Premier bundles additional software. Subscription expiry affects add-on services rather than the perpetual base; confirm entitlements separately for either hardware condition.
WS-C3850-32XS-E includes C3850-NM-8-10G with eight 1G/10G interfaces. The hardware also supports C3850-NM-4-10G for four 1G/10G interfaces or C3850-NM-2-40G for two 40G interfaces. The uplink bay accepts one module, so a module change replaces the included uplink configuration. Specify optics for the chosen interfaces and fiber links.
Catalyst 3850 supports nine members through StackWise-480 with 480 Gbps stacking bandwidth. STACK-T1-50CM=, STACK-T1-1M= and STACK-T1-3M= provide three cable lengths for the data stack. Members need aligned software feature levels. StackPower is a separate power interconnect, so specify data-stack cabling independently of any power-sharing connections.
Catalyst 3850 with IP Services supports full OSPF, EIGRP, BGPv4 and IS-ISv4, plus OSPFv3 and EIGRPv6 for IPv6. PIM-SM, PIM-DM and SSM support multicast applications. The hardware scale is 24000 IPv4 routes including ARP and learned routes; size routing and multicast requirements against the appropriate feature set and tables.
WS-C3850-32XS-E ships with PWR-C1-715WAC in the first power bay; the second bay is empty, so redundancy is optional rather than included. A second PWR-C1-715WAC= can be specified separately. The standard input is 100-240V AC, and the chassis also supports power supplied through a StackPower connection.
WS-C3850-32XS-E includes IP Services, while WS-C3850-32XS-S includes IP Base on the same 32-interface bundle. Full OSPF, EIGRP, BGPv4 and IS-ISv4 belong to the IP Services tier. Both models are discontinued: the E variant suits advanced-routing requirements in retained installations, while the S variant matches existing IP Base deployments.
WS-C3850-32XS-E includes C3850-NM-8-10G and exposes 32 interfaces, whereas WS-C3850-24XS-E supplies 24 fixed SFP+ interfaces without C3850-NM-8-10G. Both carry IP Services and are discontinued. The bundle suits an existing installation needing eight additional uplinks; the base model suits a purchase with an independently specified network module.
C9300X-24Y provides 24 native 25G fiber ports, whereas WS-C3850-32XS-E uses native 10G SFP+ interfaces. C9300X-24Y is the current migration model; the discontinued 3850 bundle instead matches retained 10G installations. Buyers moving to 25G should specify the replacement configuration separately rather than assume equivalent uplink or software packaging.
WS-C3850-32XS-E supports 640 Gbps switching capacity and 454.55 Mpps forwarding on its bundled hardware configuration. Switching capacity and packet-forwarding rate describe different limits, so compare both against the traffic design. StackWise-480 adds a separate 480 Gbps stacking interconnect; that figure is not the standalone switching-capacity rating.
