N3K-C3548-X-SPL3A is a low-latency Layer 3 data center switch with 48 fixed 1G/10G SFP+ interfaces and the L3 plus Algo Boost promotional bundle. The interfaces accommodate server-facing connections and uplinks without a separate removable uplink card. Cisco NX-OS provides the operating environment for managed switching and routing. The Nexus 3548-X occupies one rack unit within the Nexus 3500 family, serving top-of-rack deployments rather than powered endpoint access. The discontinued N3K-C3548-X-SPL3 is the L3-only promotion; the distinction is bundled Algo Boost capability rather than additional interfaces. This is a non-PoE switch, so attached equipment needs an independent power source.

960 Gbps switching capacity supports line-rate traffic across the enabled interfaces. 720 Mpps forwarding supplies the packet-processing figure for traffic sizing independently of aggregate bandwidth. OSPFv2 supports 256 routes under the Base license; LAN Enterprise adds BGP and full EIGRP, making the installed entitlement relevant when reproducing an existing routing configuration. N3K-C3548-X-SPL3A provides 18 MB of packet buffering, with 6 MB shared among each 16-port group; include that allocation when planning burst-sensitive connections. 213W maximum power consumption supplies the figure for power provisioning, while typical operation is 112W. System memory and boot flash are 4 GB each, distinguishing the X hardware from extended-memory configurations. Four hot-swappable fans provide active cooling rather than fanless operation.
N3K-C3548-X-SPL3A is offered new sealed or certified refurbished, with ORM warranty coverage of up to 3-year extended on new hardware and up to 1 year on certified refurbished units. Refurbished units are inspected and bench-tested, including optics bay recognition, with firmware verified and configuration wiped to factory default. Specify condition, quantity and required entitlements on the PO; returns cover every condition for 30 days, terms apply, while Cisco's separate 1-year limited hardware warranty cannot extend service beyond January 31, 2027. ORM Systems accepts POs, offers Net-30 for government and handles RMA with advance replacement across UK, EU, US and MEA orders.

When replacing a discontinued N3K-C3548P-BA-L3A in an existing installation, preserve the intended airflow and input-power arrangement rather than transferring the old bundle assumptions to the replacement order. Record the required airflow direction, installed supply type and software entitlements before issuing the PO.
Before reproducing a production configuration in a staging rack, reserve independent access through the RS-232 console and dedicated 10/100/1000 management interface. Those interfaces serve administration rather than production links. Include the console-access arrangement and management-network requirements in the staging purchase checklist.
Native QSFP uplink ports
N3K-C3548-X-SPL3A has SFP+ cages, not native QSFP ports; logical 40G operation combines four sequential SFP+ interfaces instead of providing a dedicated QSFP uplink.
Cisco support beyond January 2027
Cisco support for N3K-C3548-X-SPL3A ends January 31, 2027. Review current replacement N3K-C3548P-XL when the purchase must avoid the discontinued X model's support cutoff.

N3K-C3548-X-SPL3A identifies the Nexus 3548-X 48-port SFP+ promotional bundle with L3 and Algo Boost. N3K places the product in the Nexus 3000 family, C3548 identifies the 48-port model, X identifies the enhanced generation, and SPL3A identifies the L3 plus Algo Boost promotion. Specify airflow and input power separately.
The Nexus 3548-X supports CLI management through the serial console, SSHv2 or Telnet, plus XML NETCONF, SNMP v1/v2/v3 and Cisco DCNM. In-band management and the dedicated Ethernet management port are available. Python scripting and POAP support automation; specify which access and provisioning methods the deployment requires.
N3K-C3548-X-SPL3A is discontinued, with Cisco's last date of support set for January 31, 2027. Its end-of-sale date was January 31, 2022, and vulnerability/security support ended January 30, 2025. N3K-C3548P-XL is the current replacement; remaining Cisco support for the older model depends on an active entitlement.
ORM Systems offers N3K-C3548-X-SPL3A new sealed or certified refurbished, with up to 3-year extended ORM warranty on new hardware and up to 1 year on refurbished units. Returns cover every condition for 30 days; terms apply. Cisco's separate 1-year limited hardware warranty is bounded by the January 31, 2027 last date of support.
N3K-C3548-X-SPL3A supports Base, LAN Enterprise and Algo Boost feature licenses, plus NX-OS Essentials or NX-OS Advantage subscriptions starting at 3 years and NX-OS Advantage perpetual licensing. LAN Enterprise requires Base. The L3 and Algo Boost promotional identity does not replace checking installed entitlements and NX-OS release compatibility before quoting.
N3K-C3548-X-SPL3A replaced discontinued N3K-C3548P-BA-L3A, N3K-C3548P-BD-L3A, N3K-C3548P-FA-L3A and N3K-C3548P-FD-L3A, whose end-of-sale date was October 7, 2016. Those earlier bundles differed in airflow and AC or DC input. Preserve those deployment requirements when specifying replacement stock rather than treating the promotional PID as an airflow selection.
The Nexus 3548-X accepts SFP-10G-SR for multimode fiber, SFP-10G-LR for single-mode fiber and SFP-H10GB-CU1M for a 1 m direct-attach copper link. Choose the connection type for each link, then confirm the matching far-end interface before putting the optics or cable on the purchase order.
N3K-C3548-X-SPL3A supports 24000 IPv4 routes and 64000 MAC entries in normal mode, versus 4000 routes and 8000 MAC entries in warp mode. Select the forwarding mode against the required route and address scale before reproducing a production configuration; the normal-mode limits are not warp-mode limits.
N3K-C3548-X-SPL3A includes the L3 and Algo Boost promotion, while discontinued N3K-C3548-X-SPL3 is the L3-only promotion. Both use 48 SFP+ ports and both are discontinued. Existing estates requiring Algo Boost match the former bundle; estates matching an L3-only spare specification distinguish the latter.
N3K-C3548P-XL has 16 GB of system memory, compared with 4 GB in N3K-C3548-X-SPL3A, and is the current replacement for the discontinued X bundle. The XL model suits a current replacement purchase; the older bundle matches an existing X-generation spare requirement rather than the extended-memory configuration.
N3K-C3548-X-SPL3A enables 48 SFP+ ports, whereas discontinued N3K-C3524-X-SPL3A enables 24; both are L3 and Algo Boost promotional bundles. Both models are discontinued. The former matches an existing 48-port spare requirement, while the latter matches an existing 24-port installation; neither distinction removes the need to plan around the support deadline.
