Port Configuration and PoE+ Support
The switch has 24 x 10/100/1000BASE-T PoE+ (IEEE 802.3at) downlink ports and 4 x fixed 1G SFP uplink ports for flexible fibre back connectivity. The total PoE budget is 505 W, and it can power IP phones, Wi-Fi 6/6E access points, cameras and IoT devices. The chassis includes one 715 W AC power supply (redundant unit optional) and three field-replaceable fans for high availability and N+1 redundancy.




Performance and Stacking
The switch has a switching capacity of 56Gbps and a forwarding rate of 41.66Mpps. Bandwidth stacking (StackWise™ 320 technology) is expanded to 320 Gbps, switching capacity is expanded to 376 Gbps and forwarding rate is expanded to 279.76 Mpps with up to eight switches in a single logical stack with sub-50-ms failover protection. It supports 32,000 MAC addresses, 4,094 VLANs and a packet buffer size of 16 MB.
Security & Administration
It runs Cisco IOS XE and the UADP 2.0 ASIC and provides hardware-based AES-256 MACsec encryption, 802.1X authentication, TrustSec and Encrypted Traffic Analytics for encrypted threat visibility. Management options include CLI, NETCONF, RESTCONF, gRPC and Cisco Catalyst Center for policy based automation.



Software Licensing & Best Deployment
Or get it with Network Essentials (C9300L-24P-4G-E) for routed access and segmentation-ready features. Or Network Advantage (C9300L-24P-4G-A) for full dynamic routing (OSPF, EIGRP, BGP, IS-IS) and VRF-based segmentation. Ideal for campus access layers, branch offices and converged PoE+ systems requiring secure, high density Gigabit connectivity.
