Managed L2/L3-switch Cisco Catalyst C9300L-24T-4X-A

The Cisco Catalyst C9300L-24T-4X-A is a managed L2/L3 switch offering 24 Gigabit Ethernet RJ-45 ports (10/100/1000) and four 10G uplink ports. Designed as part of the Catalyst 9300 family, it provides a high-density, stackable enterprise switching platform suitable for secure, scalable campus and branch networks and supports Cisco IOS XE programmability and features for IoT and advanced security.

Advantages

This switch supports stackable deployment with Cisco StackWise technology and delivers high stacking bandwidth and flexible uplink options. It uses the UADP 2.0-based architecture and an x86-class CPU to enable increased memory, improved throughput, and the ability to host containerized or third-party applications. Power features include support for high-density PoE/PoE+ and Cisco StackPower for resilient power sharing across a stack. Cisco IOS XE provides advanced security, management, and programmability capabilities.

Suitable for

• Enterprise campus access layer
• Branch office aggregation and distribution
• High-density wired access for Wi‑Fi 6 APs and IoT devices
• Racks requiring 24-port Gigabit connectivity with 10G uplinks

Key specifications

• Ports: 24 × Gigabit Ethernet (10/100/1000) RJ-45
• Uplinks: 4 × 10G (SFP+/QSFP depending on model variant)
• Switch type: Managed L2/L3
• MAC address table: 32,000 entries (as specified)
• Networking standards: IEEE 802.1s, 802.3z, 802.3u, 802.3bz, 802.3ap, 802.3af, 802.3ad, 802.1x, 802.1w, 802.1p, 802.1Q, 802.1D
• Color: Grey

How to use

Mount the switch in a standard 19-inch rack and connect power according to site requirements. Connect access devices to the 24 Gigabit RJ-45 ports and use the 10G uplink ports for aggregation to the core or distribution layer. Use Cisco IOS XE CLI, web-based management, or Cisco DNA Center for initial configuration, switch stacking with StackWise, VLAN and routing setup, and enabling PoE or UPOE features where applicable. Follow Cisco configuration guides for stack formation and high-availability settings such as NSF/SSO.

Recommendations

For resilient deployment, configure StackWise stacking and StackPower where available, enable appropriate QoS and security policies via Cisco IOS XE, and plan uplink capacity using the 10G ports for aggregation. Verify power budget if deploying PoE devices and ensure firmware is updated to a supported IOS XE release.
