The Cisco C9300L-48T-4G is a fixed-configuration, stackable enterprise switch equipped with 48 dedicated 10/100/1000 Mbps RJ45 Gigabit Ethernet data ports and 4 fixed 1G SFP uplink ports. Operating on Cisco’s x86 CPU architectural framework paired with the open, programmable Cisco IOS XE operating system, it provides high-throughput wire-speed switching for data-intensive networks.

Unlike standard modular enterprise switches like the Cisco C9300-48T Switch or the high-density Cisco C9300-48U Switch, the C9300L variant integrates fixed uplinks directly into the chassis. This streamlined hardware architecture significantly reduces entry cost while retaining the full corporate capability of Catalyst 9300 architecture, including StackWise-320 technology, Cisco DNA software readiness, Encrypted Traffic Analytics (ETA), and enterprise-grade resilience.

If your infrastructure requires flexible modular uplink expansion options rather than fixed uplinks, consider exploring the core modular Catalyst platforms such as the Cisco C9300-24T Switch or the high-throughput fiber variant Cisco C9300-24S Switch.

2. Key Features and Hardware Specifications

The core capability of the C9300L-48T-4G stems from its optimized hardware pipeline and application-specific integrated circuits (ASICs). Designed for seamless enterprise integration, the switch provides an impressive feature set tailored for high-availability access layers.

• Port Configuration: 48 Port 10/100/1000 Network Ports (Data Only) + 4x 1G SFP Fixed Uplinks.
• Stacking Throughput: StackWise-320 support delivering up to 320 Gbps of stacking bandwidth across up to 8 units.
• Switching Capacity: 104 Gbps bandwidth capacity standalone (up to 424 Gbps when stacked).
• Forwarding Rate: 77.38 Mpps (Million Packets Per Second) throughput rate.
• Power Supply Options: Dual redundant, field-replaceable power supplies (default 350W AC).
• System Memory: 8 GB DRAM and 16 GB Flash memory for deep buffer allocation and fast operating system execution.
• Operating System: Universal Cisco IOS XE Release with advanced automation, telemetry, and patchability.

For organizations looking for similar port density in lighter-duty campus environments or lower budget tier branches, compare this model with the Cisco C9200L-48T-4G Switch or the SMB-focused Cisco C1300X-48T-4X Switch.

The following detailed technical specifications illustrate the operational parameters of the Cisco C9300L-48T-4G switch across performance, hardware specs, and software capabilities:

4. Advanced Enterprise Stacking with StackWise-320

One of the primary benefits of investing in the C9300L line over legacy switching equipment is the inclusion of Cisco StackWise-320 technology. StackWise-320 is purpose-built for stackable access layer deployment, giving network operators the ability to combine up to 8 switches into a single logical management entity.

When stacked using dedicated stacking cables, the switch pool operates with unified control plane logic, single-IP management, and cross-stack EtherChannel capability. This creates unmatched network resiliency and seamless load distribution without triggering Spanning Tree Protocol (STP) blocking on inter-switch connections.

If your enterprise topology requires optical fiber stacking or higher-speed 10G/25G stacking backplanes, explore the full-scale Catalyst 9300 fiber stack series, including the Cisco C9300-48S Switch or the ultra-high bandwidth Cisco C9300X-24Y-E Switch.

5. Security, Automation, and Cisco Software Ecosystem

Modern enterprise networks face ever-evolving security risks. The Cisco C9300L-48T-4G switch provides end-to-end zero-trust network protection through hardware-anchored security systems integrated into Cisco’s Unified Access Data Plane (UADP) ASICs.

Key Security Features:

• Encrypted Traffic Analytics (ETA): Analyzes netflow patterns to identify malware hidden in encrypted streams without breaking SSL/TLS encryption.
• Hardware Trust Anchor: Secure Unique Device Identification (SUDI) ensures authenticated hardware integrity and prevents unauthorized firmware tampering.
• Cisco TrustSec & SGTs: Implements Security Group Tags for automated micro-segmentation across the corporate LAN.
• MACsec-128 Encryption: Provides link-layer encryption between switch nodes to safeguard data transfer against wiretapping.

Network Automation and Telemetry

Powered by Cisco IOS XE, the C9300L-48T-4G supports modern network automation tools, including NETCONF, RESTCONF, YANG models, and Ansible playbooks. Streaming telemetry gives real-time performance statistics directly to central monitoring dashboards, reducing operational downtime and automating troubleshooting tasks.

For organizations deploying large-scale Enterprise IP Telephony or unified communication endpoints alongside high-security access switching, complement this hardware with enterprise VoIP endpoints such as the Cisco DP-9861-K9 IP Phone or the premium touch-screen Cisco DP-9871-K9 IP Phone.

7. Use Cases and Deployment Scenarios

The versatility of the Cisco C9300L-48T-4G makes it ideal for a wide variety of enterprise commercial network setups:

A. Commercial Office Workstations

In environments where desk computers, printers, network-attached storage (NAS), and desktop docking stations connect through direct copper wiring without requiring PoE power, the C9300L-48T-4G offers a cost-effective 48-port Gigabit solution. If you need a smaller 24-port footprint for smaller departments, the Cisco C9300L-24T-4G Switch or the Cisco C9200L-24T-4G Switch provide matching efficiency at reduced port counts.

B. Enterprise Voice-Over-IP (VoIP) Networks (With External Power)

While the C9300L-48T-4G is a data-only switch, it frequently serves as the voice transport backbone when IP phones are powered via dedicated power adapters or inline power injectors. It integrates seamlessly with business telephony infrastructure, supporting voice VLANs and priority queuing for devices like the Cisco DP-9841-K9 IP Phone and Cisco DP-9851-K9 IP Phone.

However, if native Power over Ethernet (PoE+) is required directly from the switch to eliminate wall adapters, you should opt for PoE-enabled switch alternatives like the Cisco C9300-48P Switch or the Cisco C9300-24P Switch.

C. Data Center & Server Rack Access Switching

With its high-speed backplane and 4x 1G SFP fiber uplinks, the C9300L-48T-4G serves as an effective Top-of-Rack (ToR) management and data access switch for rack server management. For high-density routing or core distribution layer needs, combine this switch with core routers such as the MikroTik CCR2116-12G-4S Router or high-performance core switches like the Cisco C9500-48Y4C-E Switch.

10. Frequently Asked Questions (FAQ)

Q1: Can the Cisco C9300L-48T-4G switch be stacked with standard Cisco C9300 switches?

No. Cisco C9300L switches utilize StackWise-320 technology with fixed uplink hardware, meaning C9300L models can only be stacked with other C9300L series switches. Standard Catalyst C9300 switches (like the C9300-24T or C9300-48T) use StackWise-480 and modular uplink architectures and must be stacked within their own product grouping.

Q2: Does the C9300L-48T-4G support PoE or PoE+ device powering?

No. The “48T” in the model name indicates that all 48 Gigabit Ethernet ports are data-only ports. If your deployment requires Power over Ethernet for IP phones or access points, you should consider models such as the Cisco C9300-48P Switch, C9200L-48P-4G-E, or the smaller C9200L-24P-4G-E Switch.

Q3: Can the uplink ports on the C9300L-48T-4G be upgraded to 10G SFP+?

No. On C9300L models, the 4x 1G SFP uplinks are fixed to the chassis motherboards and cannot be modularly swapped out. If you anticipate needing 10G uplinks in the future, we recommend purchasing 10G-native fixed models like the Cisco C9300L-24T-4X Switch or selecting modular Catalyst models such as the C9300-48T fitted with 10G expansion modules.

Q4: What license packages are required for the Cisco C9300L-48T-4G switch?

The C9300L series operates using Cisco DNA subscription licensing structure (available in Network Essentials or Network Advantage tiers). Network Essentials covers core Layer 2, static/routed Access Layer 3, and basic telemetry, while Network Advantage unlocks full Layer 3 routing protocols (OSPF, BGP, EIGRP), advanced automation, and security segmentation tools.
