N3K-C3524-X-SPL3A combines ultra-low-latency Layer 3 switching, 24 enabled 10 Gigabit Ethernet SFP+ ports and the Algo Boost promotion. Fixed interfaces carry server connections and network uplinks without a separate modular uplink bay. The Nexus 3524-X occupies 1U in a data center rack and supports fiber connections rather than powered copper access for phones or cameras. Hardware multicast NAT and egress-latency monitoring support trading and server environments where packet handling and visibility are purchase requirements. N3K-C3524-X-SPL3 provides the Layer 3 promotion without the additional Algo Boost bundle; both ordering forms are discontinued. The Cisco Nexus 3500 platform also supports filtered traffic mirroring and timestamping for monitoring traffic alongside production switching.

480 Gbps switching capacity supports line-rate traffic across the enabled interfaces, while 360 Mpps forwarding defines packet-processing throughput. 193W maximum power consumption provides the upper figure for rack power allocation rather than the typical operating draw. N3K-C3524-X-SPL3A has 4 GB of DRAM and 4 GB of flash for the NX-OS runtime and software images. Normal mode accommodates 64000 MAC addresses and 24000 IPv4 unicast routes; those totals must remain separate from routing-license restrictions. OSPFv2, EIGRP and BGP are available through the applicable routing entitlements, while the Base license limits OSPFv2 to 256 routes. Management combines serial-console access, SSHv2 or Telnet CLI sessions, Cisco DCNM, SNMP and XML over NETCONF. LACP supports aggregated Ethernet connections, and RSTP/MSTP provide spanning-tree operation. An 18 MB packet buffer is shared in 6 MB groups across 16 ports, making buffer allocation relevant when analyzing congestion rather than treating all memory as one unrestricted pool.

When a latency-sensitive application needs warp mode, forwarding scale must be checked before selecting the operating mode. Warp mode reduces the available MAC table to 8000 entries and IPv4 unicast routing to 4000 routes. Specify the required latency mode and validate the expected address and route population before the purchase order.
When equipment is being standardized across racks with different aisle orientations, airflow direction becomes an ordering requirement. N2200-PAC-400W provides port-side exhaust, while N2200-PAC-400W-B provides port-side intake. Match the selected power components to the rack’s required airflow direction and identify the required accessory PIDs on the purchase order.
When an existing server rack needs additional enabled interfaces, N3548-24P-UPG= activates the remaining ports without installing a removable network card. The purchase changes port entitlement rather than the physical interface arrangement. Include the activation license and verify the installed routing and Algo Boost entitlements before issuing the expansion purchase order.
PoE for powered copper endpoints
N3K-C3524-X-SPL3A has SFP+ switching interfaces rather than powered RJ-45 access ports. Phones, cameras and other PoE endpoints require separate powered access switching.
Native 25G server connections
The fixed SFP+ interfaces operate at 1G or 10G. Native 25G server ports are absent, and no removable uplink card adds that capability.
Cisco support beyond January 2027
Cisco support ends January 31, 2027. N3K-C3524P-XL is the current replacement for buyers requiring migration beyond this discontinued model’s remaining Cisco support window.

N3K-C3524-X-SPL3A identifies the Nexus 3524-X promotion with 24 enabled 10G ports, Layer 3 and Algo Boost. N3K denotes the Nexus 3000 family, C3524 identifies the 3524 model, X identifies the X generation, and SPL3A identifies the Layer 3 plus Algo Boost promotional configuration.
The Nexus 3524-X is managed through its serial console, CLI over SSHv2 or Telnet, Cisco DCNM, SNMP and XML over NETCONF. Management can use the dedicated Ethernet management interface or in-band connectivity. Role-based access control and authentication services restrict administrative access without changing the enabled switching-port entitlement.
N3K-C3524-X-SPL3A reached end of sale on January 31, 2022, and its last date of Cisco support is January 31, 2027. Security support ended January 30, 2025. N3K-C3524P-XL is the replacement, so continued hardware operation must not be confused with continued software-security maintenance.
ORM Systems offers N3K-C3524-X-SPL3A new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units. Returns are accepted within 30 days on every condition; terms apply. Cisco’s separate 1-year limited hardware warranty cannot extend beyond January 31, 2027.
N3K-C3524-X-SPL3A is the Layer 3 and Algo Boost promotional configuration, associated with legacy perpetual feature licensing. Base, LAN Enterprise and Algo Boost entitlements must be distinguished from NX-OS Essentials and Advantage subscriptions, whose minimum term is three years. Legacy feature licenses are discontinued; subscription entitlement and Smart Account handling depend on the installed software release.
N3K-C3524-X-SPL3A uses its enabled fixed SFP+ interfaces for uplinks rather than a separate uplink module. Supported optical options include SFP-10G-SR for multimode fiber and SFP-10G-LR for single-mode fiber. Identify the required optical reach and fiber type when specifying interfaces, because the chassis does not establish the optical medium by itself.
Yes, N3K-C3524-X-SPL3A can expand from 24 to 48 enabled SFP+ ports using N3548-24P-UPG=. The additional interfaces are already physically present; expansion activates their port entitlement rather than installing a network module. Port activation remains separate from routing and Algo Boost feature licensing, so verify both requirements before ordering.
The Nexus 3524-X trades forwarding-table scale for lower latency in warp mode, reducing the MAC table to 8000 entries and IPv4 unicast routes to 4000. Algo Boost enables warp mode and warp SPAN. Validate address and route requirements against the selected mode rather than applying normal-mode limits to every configuration.
N3K-C3524-X-SPL3A supports redundant internal power with port-side exhaust or port-side intake airflow. AC options include N2200-PAC-400W and N2200-PAC-400W-B respectively; DC options include N2200-PDC-400W and N3K-PDC-350W-B. Specify the required input and airflow combination rather than treating the chassis PID as a complete power-component selection.
Static routing, RIPv2, OSPFv2, EIGRP and BGP are available on N3K-C3524-X-SPL3A with the appropriate routing entitlements. The Base license limits OSPFv2 to 256 routes and provides EIGRP stub, while LAN Enterprise adds advanced routing. The normal-mode hardware total of 24000 IPv4 unicast routes is separate from those license restrictions.
The Nexus 3524-X provides 18 MB of packet buffering, arranged as 6 MB shared among each group of 16 ports. Active buffer monitoring supports congestion analysis alongside traffic mirroring. Buffer allocation is distinct from the switch’s DRAM and flash, so system-memory capacity must not be interpreted as available packet storage.
N3K-C3524-X-SPL3A adds the Algo Boost promotion to the Layer 3 configuration offered by N3K-C3524-X-SPL3. Both provide 24 enabled 10G ports and both are discontinued. The additional entitlement suits existing installations requiring NAT, warp mode or warp SPAN; the Layer 3 promotion addresses routing requirements without that additional feature bundle.
N3K-C3524-X-SPL3A enables 24 10G ports, while N3K-C3548-X-SPL3A enables 48; both are Layer 3 and Algo Boost promotional configurations. Both models are discontinued. The 24-port configuration suits an existing installation with fewer required active interfaces, while the 48-port configuration addresses an existing requirement for the full interface count from the outset.
N3K-C3524P-XL increases DRAM and flash to 16 GB each, compared with 4 GB each on N3K-C3524-X-SPL3A. The X model is discontinued, and the XL model is its current replacement. Existing hardware-matching requirements favor the X configuration; replacement purchases needing the expanded software runtime resources favor the XL configuration.
