N3K-C3548P-XL leads with ultra-low-latency data center switching in a managed Layer 3 Cisco Nexus design. The switch provides 48 fixed SFP+ ports that operate at 1 or 10 Gigabit Ethernet, and those same fixed ports serve the production downlink and uplink roles rather than relying on an empty modular bay. The hardware is Non-PoE, uses a 1RU rack-mount form factor, and belongs to the Cisco Nexus 3500 platform. Unlike copper campus access models, its front panel is built around pluggable optics and direct-attach cabling for server-facing and switch-facing links. N3K-C3524P-XL is the closest XL density sibling, with 24 fixed SFP+ ports enabled instead of the 48 fixed SFP+ ports on this SKU. The XL hardware profile adds enhanced memory for NX-OS Data Management Engine support, with 16 GB system memory and 16 GB bootflash.
960 Gbps switching capacity delivers line-rate traffic throughput across Layer 2 and Layer 3 paths. 720 Mpps forwarding rate supports dense 10G server access and aggregation without oversubscribing the fixed SFP+ front panel. OSPF, EIGRP, BGP, RIPv2, HSRP, VRRP, and VRF-Lite support routed data center designs, while STP, RSTP, MSTP, LACP, vPC, VLAN trunks, and jumbo frames cover Layer 2 fabric requirements. N3K-C3548P-XL presents one 10/100/1000 management port, one RS-232 console port, and two USB ports for operations and service access. 64000 Entries MAC table scale, 24000 IPv4 unicast routes, 4096 VLANs, 24 EtherChannels, and MTUs up to 9216 bytes give architects concrete boundaries for rack and aggregation designs. Cisco NX-OS Software Release 5.0 and later is the documented software baseline for the Nexus 3000 Series, keeping operational workflows consistent across compatible Nexus environments. The platform also provides 18 MB total buffer memory, dual hot-swappable redundant power supplies, four redundant hot-swappable fans, and forward or reversed airflow options for cooling alignment.
N3K-C3548P-XL fits the top-of-rack and compact aggregation tiers, connecting SFP+ server adapters, storage links, Twinax cables, multimode fiber optics, single-mode fiber optics, and upstream Nexus switches within one rack unit. The platform is not stackable, so resilient designs use vPC, LACP PortChannels, routed links, redundant power supplies, and matched airflow modules instead of a shared stack backplane. ORM Systems supplies this switch new and certified refurbished, and refurbished units are tested for NX-OS boot, management access, fan and PSU status, SFP+ port recognition, optic detection, and forwarding before dispatch. Buyers can request current pricing from ORM Systems for single units, rack spares, or multi-site volume projects. Enterprise purchasing teams can align warranty, airflow direction, AC or DC power supply type, compatible optics, Twinax cable quantities, and delivery requirements in the same quote for standardized procurement across multiple data center rooms.
N3K-C3548P-XL price is $14,500.00, a 50.7% saving from the Cisco list price of $29,430.00. N3K-C3548P-XL is in stock and available for next-day dispatch. (terms applied)

N3K-C3548P-XL sits at the top of a rack and terminates SFP+ links from 10 Gigabit Ethernet servers, storage adapters, and adjacent rack devices on 48 fixed 1/10G ports. Engineers run Cisco NX-OS with VLAN trunks, SVIs, PortChannels, vPC, and jumbo frames to keep east-west traffic local while presenting controlled uplinks toward aggregation. The 1RU chassis and dual redundant power supplies fit dense rack builds. The result is predictable server access with line-rate Layer 2 and Layer 3 forwarding at the rack edge.
The switch occupies a compact aggregation point where multiple access racks hand 10G SFP+ traffic into a Cisco Nexus 3500 layer. N3K-C3548P-XL uses 960 Gbps switching capacity, 720 mpps forwarding, and Algo Boost behavior to carry Layer 2 and Layer 3 flows through normal or low-latency operating designs. Engineers group links with LACP, apply VRF-Lite, OSPF, BGP, HSRP, or VRRP, and keep MTUs aligned up to 9216 bytes. The outcome is deterministic aggregation for latency-sensitive data center paths between access blocks.
N3K-C3548P-XL anchors a monitoring fabric where SPAN or tap sources feed packet brokers, analyzers, or security tools through SFP+ interfaces. Cisco Nexus Data Broker and NX-OS controls organize copied traffic across the Nexus 3500 platform, while 48 fixed 1/10G ports provide dense handoff for monitored links and tool ports. Engineers size optics, Twinax cables, PortChannels, and flow policies around the existing capture design. The network gains a dedicated collection layer that separates monitoring traffic from production forwarding paths and reduces contention around packet visibility.

N3K-C3548P-XL is a Cisco Nexus 3548-XL fixed 1RU data center switch with 48 fixed SFP+ ports that run at 1 or 10 Gbps. It belongs to the Cisco Nexus 3500 platform, which is aimed at low-latency top-of-rack switching, Layer 2/3 forwarding, and dense SFP+ server or fabric connectivity in NX-OS environments.
N3K-C3548P-XL identifies a Cisco Nexus 3000 Series switch in the 3548 platform family. The 3548 portion points to the 48-port Nexus 3548 design, while XL identifies the enhanced-memory version with a 2.5 GHz CPU, 16 GB system memory, and 16 GB bootflash memory compared with earlier Nexus 3548-X hardware.
The Cisco Nexus 3548-XL is a managed data center Ethernet switch, not a router, firewall, wireless access point, or PoE access switch. N3K-C3548P-XL provides fixed SFP+ switching for 1G and 10G links, with Cisco NX-OS software, Layer 2 switching, Layer 3 routing features, and redundant field-replaceable power and fan modules.
N3K-C3548P-XL sits in the Cisco Nexus 3500 platform within the broader Nexus 3000 Series data center switch family. It is the 48-port XL version of the Nexus 3548 design, positioned above 24-port Nexus 3524 variants for higher SFP+ density and above earlier 3548-X hardware for memory and bootflash capacity.
N3K-C3548P-XL has 48 fixed SFP+ ports supporting 1 or 10 Gigabit Ethernet operation. The switch also includes one 10/100/1000 management port, one RS-232 serial console port, two USB ports, a 1-PPS timing port, and locator controls, giving network teams separate production, management, timing, and service access paths.
N3K-C3548P-XL provides 960 Gbps switching capacity and a forwarding rate of 720 mpps. Cisco specifies line-rate Layer 2 and Layer 3 traffic throughput on all ports, with jumbo frame support up to 9216 bytes, making the switch suitable for dense 10G server access and low-latency rack aggregation.
The Cisco Nexus 3548-XL does not provide PoE or PoE+ power to endpoints. N3K-C3548P-XL is built around 48 SFP+ data ports for fiber or Twinax connectivity, so powered devices such as phones, cameras, and access points need a separate PoE access switch or an external power design.
N3K-C3548P-XL supports Layer 2 switch ports, VLAN trunks, IEEE 802.1Q, spanning tree options, EtherChannel, LACP, jumbo frames, and vPC. Layer 3 support includes routed interfaces, SVIs, PortChannels, subinterfaces, 24-way ECMP, OSPF, BGP, EIGRP, RIPv2, HSRP, VRRP, VRF-Lite, VRF-aware routing, and ACL functions for data center segmentation designs.
Cisco N3K-C3548P-XL runs Cisco NX-OS and is managed through the NX-OS CLI, the dedicated management Ethernet port, console access, and Cisco data center management tooling such as Cisco DCNM where deployed. The XL memory profile also supports the Cisco NX-OS Data Management Engine model for environments standardizing on model-driven management.
N3K-C3548P-XL is not a Catalyst-style stackable access switch with a shared stack backplane. Nexus 3500 deployments normally use vPC, PortChannels, LACP, routing protocols, and redundant power or fan designs to build resilient pairs or multi-switch topologies while keeping each switch as an independently managed NX-OS device.
N3K-C3548P-XL is commonly used for top-of-rack 10G server access, low-latency data center switching, and SFP+ aggregation between racks. Its 48 fixed 1/10G ports, 960 Gbps switching capacity, and line-rate Layer 2/3 forwarding make it practical where many server or storage links need predictable switching inside a 1RU footprint.
The Cisco Nexus 3548-XL fits small to medium data center racks, lab fabrics, colo pods, and refresh projects that need 48 fixed SFP+ ports per switch. It suits teams standardizing on 10G server connectivity, redundant power, hot-swappable fans, and NX-OS operations without moving to higher-density 25G or 100G platforms.
N3K-C3548P-XL is suitable for low-latency switching designs in the Cisco Nexus 3500 family. The platform includes Cisco Algo Boost technology, line-rate Layer 2 and Layer 3 forwarding, normal and warp operating modes, and hardware-assisted visibility features, so it fits latency-sensitive east-west traffic and packet monitoring architectures.
N3K-C3548P-XL fits monitoring fabrics built with Cisco Nexus Data Broker, taps, SPAN sources, and analysis tools. The switch provides dense SFP+ handoff for copied traffic, while NX-OS and Nexus Data Broker workflows help organize monitored flows across one or more Nexus 3500 switches instead of relying on a separate matrix switch.
N3K-C3548P-XL supports Cisco SFP+ 10G options listed for the Nexus 3500 platform, including SFP-10G-SR for multimode fiber, SFP-10G-LR for single-mode fiber, SFP-10G-ER, DWDM-SFP10G variants, and SFP-H10GB Twinax cable assemblies in supported lengths. Optic selection should match distance, fiber type, airflow plan, and Cisco compatibility guidance.
N3K-C3548P-XL supports selected Gigabit Ethernet SFP modules for 1G operation, including GLC-TE, GLC-SX-MM, GLC-SX-MMD, GLC-LH-SM, and GLC-LH-SMD in Cisco Nexus 3500 compatibility listings. This lets teams reuse supported copper, multimode, or single-mode 1G links where a rack still contains mixed-speed devices or legacy service connections.
Cisco Nexus 3548-XL integrates with Cisco NX-OS operational workflows and Cisco DCNM for data center network management where that platform is deployed. N3K-C3548P-XL also fits Cisco Nexus Data Broker monitoring designs, which use Nexus switches, taps, SPAN sources, and OpenFlow-enabled traffic steering for packet capture infrastructure.
N3K-C3548P-XL integrates through standard Ethernet and routing features such as IEEE 802.1Q VLANs, IEEE 802.1w RSTP, IEEE 802.1s MSTP, LACP through IEEE 802.3ad and 802.1ax, jumbo frames, OSPF, BGP, EIGRP, RIPv2, HSRP, VRRP, VRF-Lite, and vPC in Cisco Nexus data center designs.
N3K-C3548P-XL is the enhanced-memory successor option for N3K-C3548P-10GX in Cisco migration listings. Both are 48-port Nexus 3548-family SFP+ switches, but the XL model adds a 2.5 GHz CPU, 16 GB system memory, and 16 GB bootflash memory, while the 3548-X generation lists 4 GB system memory and 4 GB bootflash.
N3K-C3548P-XL provides 48 active fixed SFP+ ports, while N3K-C3524P-XL is the 24-port XL variant in the same Nexus 3500 platform. The 3548-XL is the better fit when the rack needs full 48-port density immediately; the 3524-XL fits smaller racks or staged growth with lower active port requirements.
N3K-C3548P-XL is newer than the original N3K-C3548P-10G Nexus 3548 hardware and adds the XL memory profile. The original 3548 model provides 48 SFP+ ports and 960 Gbps switching capacity, while the XL version keeps the 48-port 1/10G design and increases system memory and bootflash to 16 GB.
N3K-C3548P-XL is listed by Cisco as the replacement product for several Nexus 3548-X part numbers, including N3K-C3548P-10GX and N3K-C3548-X-SPL3A. That makes it the natural same-family option when a buyer wants the Nexus 3548-X port layout with the XL enhanced-memory hardware profile and NX-OS operational model.
