Cisco Catalyst 9300L Switch

Managed Access Switches Cisco Catalyst 9300L for Enterprise Networks

Cisco Catalyst 9300L is a series of fixed-uplink managed access-layer enterprise-class switches from Cisco, part of the flagship Catalyst 9000 family. The “L” index models are designed as a direct and more affordable replacement for the popular Catalyst 3650 series. They offer the same ASIC UADP 2.0/3.0 compute capabilities and support for the Cisco SD-Access software-defined access architecture, but feature fixed (factory-soldered) uplinks instead of modular network modules, reducing total cost of ownership (TCO) for branches and mid-sized enterprise networks. The devices run on the modern modular Cisco IOS XE operating system.

The Catalyst 9300L series addresses access-layer tasks in the enterprise network: connecting workstations, IP phones, Wi-Fi 6E/7 access points, IP cameras, and other endpoint devices. With support for StackWise-320 stacking, advanced PoE technologies, and hardware redundancy, the switches enable building fault-tolerant access networks without excessive complexity and with minimal operational costs.

Use Cases

The Cisco Catalyst 9300L is the optimal solution for organizations requiring:

• Mid-sized enterprise networks (access layer)
• Branch and remote office networks (Branch, ROBO)
• Connecting Wi-Fi 6E/7 access points via multigigabit mGig ports
• Building stacks of multiple switches with unified management
• Powering IP cameras, IP phones, and terminals via PoE+/UPOE
• Network segmentation and micro-segmentation (TrustSec SGT, VXLAN, SD-Access)
• Protection against threats inside encrypted traffic (ETA)

Interface Architecture and Modifications

The Catalyst 9300L line is divided by downlink port types and built-in uplink configurations:

• Downlink ports. Versions with 24 or 48 ports are available. By media type, they are divided into standard copper 1G (Data-only / PoE+), multigigabit Cisco UPOE/mGig ports (100M/1G/2.5G/5G/10G for connecting high-performance Wi-Fi 6E/7 access points), and fully optical SFP versions.
• Fixed uplinks (selectable when purchasing a specific model):
  • 4 × 1G SFP — for basic connections
  • 4 × 10G SFP+ — the most common enterprise standard
  • 2 × 40G QSFP+ — for high-speed aggregation backbones

Key Technology Features and Benefits

• Intelligent stacking (StackWise-320). The switches support combining up to 8 devices into a single logical stack using dedicated ports and cables on the rear panel. Total stack bus throughput is 320 Gbps.

  Important architectural limitation: Catalyst 9300L switches can only stack with each other (9300L model with 9300L model). They cannot be combined into a single stack with classic Catalyst 9300 switches (which use StackWise-480) or Catalyst 9300X.

• Advanced PoE+ and UPOE. Models with power support can deliver standard PoE+ (up to 30 W per port) or Cisco UPOE (up to 60 W per port). The following technologies are supported:
  • Perpetual PoE: continuous power delivery to endpoint devices (IP cameras, terminals) even during switch reboot.
  • Fast PoE: power delivery begins within the first 15–20 seconds after the switch is connected to the network, long before IOS XE fully boots.
• Hardware redundancy. Unlike older 3650 lines, the 9300L series supports two redundant power supplies (rated from 350W to 1100W AC/DC) and a removable redundant hot-swap fan module.

Security and Software Functionality

• Encrypted Traffic Analytics (ETA). Thanks to the built-in ASIC, the switch can detect malware and hidden threats inside encrypted sessions (SSL/TLS) without decrypting them, using machine learning algorithms based on flow metadata.
• Macro- and micro-segmentation support. Hardware support for VXLAN, LISP, and classic TrustSec (SGT) enables end-to-end security policies both in traditional networks and within the Cisco SD-Access concept managed by Cisco DNA Center / Catalyst Center.
• Telemetry and automation. Full support for Model-Driven Telemetry (NETCONF/YANG), local application container hosting (Application Hosting) thanks to the built-in USB 3.0 SSD port.

Cisco DNA Licensing Model

A base term-based Cisco DNA license (3, 5, or 7 years) is required for the switch to operate. Two key packages are available:

1. Network Essentials / DNA Essentials: basic L2/L3 switching functionality, static OSPF, basic monitoring.
2. Network Advantage / DNA Advantage: advanced protocols (BGP, full OSPF, VRF), stacking support, SD-Access integration, advanced security (ETA), and full automated monitoring.
