N3K-C3548P-BA-L3A combines Algo Boost technology with 48 fixed 1/10G SFP+ interfaces and Layer 3 switching in a 1U chassis. The Nexus 3548 bundle uses AC power and port-side intake airflow, drawing cooling air through the network-facing side. Fixed interfaces serve server connections and upstream links without a removable uplink card. Within the Nexus 3500 family, this configuration addresses low-latency data center networking, including trading and high-performance computing environments. Algo Boost adds NAT, warp mode, and warp SPAN to the software feature set. The discontinued N3K-C3548P-FA-L3A reverses the airflow direction to port-side exhaust, making airflow orientation an important distinction when matching existing equipment.

960 Gbps switching capacity supports line-rate Layer 2 and Layer 3 traffic across the interfaces, while 720 Mpps forwarding capacity accommodates packet-intensive workloads. 265W maximum consumption provides the electrical planning ceiling; typical operating consumption is 152W. Normal mode supports 64000 MAC addresses and 24000 IPv4 unicast routes, while the shared packet buffer provides 18 MB for traffic queuing. N3K-C3548P-BA-L3A carries 4 GB of system memory and 2 GB of bootflash for software operation and local storage. LAN Enterprise routing enables OSPFv2, EIGRP, BGP, and VRF-Lite; multicast functions include PIM-SM, SSM, and MSDP. LACP and MSTP support link aggregation and spanning-tree operation. Management includes CLI access, SSHv2, Telnet, SNMP, XML through NETCONF, and Cisco DCNM. Dual redundant power supplies and four fans support the cooling and power architecture. Native copper access ports and PoE output are absent.
ORM Systems offers N3K-C3548P-BA-L3A new sealed or certified refurbished, with up to 3-year extended warranty for new units, up to 1 year for certified refurbished units, and 30-day returns on every condition; terms apply. Refurbished units are inspected and bench-tested for power-on, POST, clean boot, rated-speed port links, and optics bay recognition, with firmware verified and configuration wiped to factory default. Specify condition and software entitlements on the PO; Cisco's original 1-year limited hardware warranty has ended, and Cisco service ended October 31, 2021. Enterprise and volume orders support PO acceptance, Net-30 for government, and RMA with advance replacement, with regional stock and RMA across the UK, EU, US, and MEA.

When a low-latency trading configuration requires warp mode, the forwarding limits change to 8000 MAC addresses and 4000 IPv4 unicast routes. Inventory learned addresses and routed prefixes for that operating mode, then specify the intended mode and applicable Algo Boost entitlement before the PO.
When an existing rack needs a like-for-like spare, two physical management connectors do not provide two active management links: only one is enabled. Match the installed unit's airflow, power arrangement, software rights, and management cabling before placing a spare on the PO.
When staging must reproduce an existing NX-OS configuration, support for 9216-byte jumbo frames gives the acceptance plan a specific frame-size limit. Define the test traffic, saved configuration, console access, and required software entitlements before specifying the lab unit on the PO.
Active Cisco hardware service coverage
Cisco support ended October 31, 2021. N3K-C3548P-XL is the current migration model after the discontinued intermediate replacement; specify its software and airflow requirements separately.
Native 25G or 100G interfaces
The fixed network interfaces are SFP+ cages operating at 1G or 10G. The chassis has no native 25G or 100G network ports.
vPC operation in warp mode
vPC is not supported in warp mode. A deployment requiring vPC must use normal mode rather than combining vPC with the reduced-latency warp configuration.

N3K-C3548P-BA-L3A identifies a Nexus 3548 bundle with Layer 3 and Algo Boost, port-side intake airflow, and AC power. N3K places the switch in the Nexus 3000 family; C3548P identifies the 48-port SFP+ model; BA specifies reverse airflow and AC; L3A identifies the software bundle.
N3K-C3548P-BA-L3A supports CLI management through the serial console, SSHv2, and Telnet, alongside Cisco DCNM, SNMP, and XML through NETCONF. Management can use the Ethernet management connection or an in-band connection. Python scripting, configuration rollback, and Power On Auto Provisioning support configuration and operational workflows.
N3K-C3548P-BA-L3A reached end of sale on October 7, 2016, and Cisco support ended October 31, 2021. Its immediate replacement, N3K-C3548-X-SPL3A, is also discontinued. The replacement chain continues to N3K-C3548P-XL, which is the current migration model rather than another purchase of the intermediate generation.
ORM Systems offers N3K-C3548P-BA-L3A new sealed or certified refurbished, with up to 3-year extended warranty for new units and up to 1 year for refurbished units. Returns cover every condition for 30 days; terms apply. Cisco's original 1-year limited hardware warranty has ended; Cisco support ended October 31, 2021.
N3K-C3548P-BA-L3A is the Layer 3 and Algo Boost bundle. N3548-LAN1K9 enables LAN Enterprise routing and requires a Base license; N3548-ALGK9 enables NAT, warp mode, and warp SPAN. The system default supplies Layer 2, security, and management functions. Confirm the delivered software entitlements separately from the chassis condition.
N3K-C3548P-BA-L3A has 48 fixed SFP+ network ports supporting 1G or 10G operation, with no native RJ-45 access ports or PoE output. The same fixed interfaces can connect servers or upstream equipment. SFP-10G-SR supports multimode fiber links, while SFP-10G-LR supports single-mode fiber links.
The Nexus 3548 Layer 3 bundle supports OSPFv2, EIGRP, and BGP through LAN Enterprise licensing, alongside static routing and RIPv2. HSRP and VRRP provide gateway redundancy functions, while PIM-SM, SSM, and MSDP support multicast operation. LAN Enterprise requires the Base license, so entitlement verification remains part of ordering.
N3K-C3548P-BA-L3A has a published maximum consumption of 265W and typical operating consumption of 152W. The AC configuration accepts 100-240V input and uses dual redundant power supplies. Size rack electrical capacity against the maximum figure rather than treating typical consumption as the deployment ceiling.
The Nexus 3500 reduces forwarding scale in warp mode: MAC capacity changes from 64000 to 8000 entries, and IPv4 unicast route capacity changes from 24000 to 4000 routes. Warp mode trades forwarding-table scale for lower latency and requires the Algo Boost entitlement; vPC is not supported in that mode.
N3K-C3548P-BA-L3A uses port-side intake airflow, whereas N3K-C3548P-FA-L3A uses port-side exhaust airflow. Both are AC-powered Layer 3 and Algo Boost bundles, and both are discontinued. For matching existing equipment, BA corresponds to a cold aisle facing the ports; FA corresponds to a hot aisle facing the ports.
N3K-C3548P-BA-L3A uses AC power, while N3K-C3548P-BD-L3A uses DC power. Both bundles use port-side intake airflow and include Layer 3 and Algo Boost. Both are discontinued, so the distinction matters when matching replacement stock: BA matches AC-fed racks, while BD matches installations wired for DC power.
N3K-C3548P-XL has 16 GB system memory and 16 GB bootflash, versus 4 GB and 2 GB on N3K-C3548P-BA-L3A. The original bundle is discontinued and unsupported. Existing configurations may require original hardware for matching; the XL is the current migration choice for a replacement-generation purchase.
The Nexus 3548 occupies 1U and measures 43.6 mm high, 439 mm wide, and 467 mm deep, with a weight of 7.9 kg. Allow space for network cabling and unobstructed airflow. The operating environment must remain within 0°C to 40°C, and the intake side must face the cold aisle.
