Core Architecture & Technical Capabilities
The Cisco Nexus N3K-C3048TP-1GE is a 1RU Layer 2/3 switch designed for mixed-speed enterprise networks, combining 48x1GBase-T copper ports and 4x10G SFP+ uplinks. Key specifications include:
- Switching Capacity: 176 Gbps with 132 Mpps forwarding rate, supporting wire-speed traffic handling for VoIP and video conferencing.
- Power Efficiency: Dual 300W hot-swappable PSUs (AC/DC options) consuming 120W typical power, featuring Power over Ethernet (PoE) support for IoT devices.
- Management: Includes 2x1G management ports and NX-OS 7.0(3)I7(2) firmware with automated provisioning via Cisco DCNM.
Competitive Advantages Over Similar Models
Legacy Network Modernization
Unlike fiber-centric models like N3K-C3172PQ, the N3K-C3048TP-1GE simplifies upgrades in copper-dominated environments. Its 10G SFP+ uplinks enable seamless spine-leaf integration without cabling overhauls.
Feature-Rich Security
- QoS: Per-port ACLs, VACL, and CoPP prioritize mission-critical traffic.
- Multicast Handling: Supports PIM-SM, IGMPv3, and MSDP for IPTV deployments.
- Buffer Management: 128K MAC address table prevents congestion in BYOD-heavy networks.

| PoE Support | Yes | No |
| Typical Use Case | Campus access layer | High-density copper core |
| Latency | ~2 μs | <1 μs |
Deployment Scenarios & Challenges
IoT-Enabled Office Networks
The switch’s PoE+ capability powers IP cameras and wireless APs while maintaining 9.3kg lightweight design for wall-mounted racks. Cisco’s validated SFP-10G-SR optics ensure <300m fiber connectivity.
Firmware Limitations
Non-XL variants require NX-OS image compression for upgrades beyond version 9.x due to 2GB bootflash constraints. The N3K-C3048TP-1GE-XL model (16GB storage) resolves this for long-term scalability.

FAQs: Critical Implementation Insights
Q: Can the 10G SFP+ ports support 25G via breakout cables?
A: No – maximum breakout capability is 4x1G per port using CAB-SFP-4SFP10G cables.
Q: Is third-party PoE injector support reliable?
A: While Cisco recommends Cisco UPOE+, ITmall.sale verifies compatibility with 802.3at/af compliant injectors.
Q: What’s the end-of-support timeline?
A: Cisco plans retirement by 2026-2027, but refurbished units remain viable through 2030 with firmware patches.
