C9300L-48UXG-4X-A Description
The Cisco C9300L-48UXG-4X-A delivers twelve multi-gig UPOE ports (10 G/5 G/2.5 G/1 G/100 M) alongside thirty-six 1 G/100 M/10 M UPOE copper ports, powered by an integrated 1100 W AC supply providing a default 675 W PoE budget. Four fixed 10 Gbps SFP+ uplinks enable fiber aggregation to distribution or core switches. Running Cisco IOS XE with the Network Advantage license, it supports wire-speed Layer 2 switching, full Layer 3 routing protocols (OSPF, EIGRP, BGP, VRF-Lite, MPLS, PIM-SM multicast), hardware-based ACLs, and advanced QoS. StackWise-320 technology provides up to 320 Gbps of stacking bandwidth across up to eight switches, presenting the stack as a single logical device for simplified management. Built-in security features include MACsec-128 encryption, 802.1X authentication, DHCP Snooping, Dynamic ARP Inspection, and TrustSec, enforcing access control and mitigating Layer 2 threats. Ideal for PoE-heavy campus and branch deployments—such as IP surveillance, Wi-Fi 6 AP aggregation, and IoT edge—this model balances multi-gig UPOE power, advanced routing, and resilient stacking.

Key Features
Multi-Gig UPOE Capability
Twelve ports negotiate speeds from 100 Mbps up to 10 Gbps and deliver up to 90 W each; thirty-six 1 G ports deliver 30 W each, ideal for high-power IoT and converged devices.
Advanced Layer 3 Routing
Network Advantage license unlocks OSPF, EIGRP, BGP, VRF-Lite, MPLS, and PIM-SM multicast—enabling robust campus or branch routing designs with segmentation and multicast support.
StackWise-320 Resiliency
Provides up to 320 Gbps of stack bandwidth for up to eight units, enabling a single, highly available control plane; hot-swap stack modules facilitate zero-touch maintenance.
Robust Security Suite
MACsec-128 encryption, 802.1X authentication, DHCP Snooping, Dynamic ARP Inspection, and TrustSec enforce secure device onboarding and mitigate Layer 2 threats at the edge.
Wire-Speed QoS & ACLs
Hardware-based QoS supports eight queues per port, 802.1p/DSCP classification, and Flexible NetFlow (64 000 flows), while ACLs scale to 5 120 entries for granular traffic control.
Cisco IOS XE Programmability
Supports RESTCONF, NETCONF, gNMI, on-box Python scripting, YANG-based telemetry, and App Hosting—enabling seamless integration into DevOps workflows and automation pipelines.
Application Scenarios
Acts as a high-capacity aggregation switch in campus core closets, providing 4 × 10 Gbps uplinks to distribution and powering multi-gig edge devices like Wi-Fi 6 APs and digital signage.
Serves as the primary routing gateway in a branch environment, leveraging BGP for multi-site connectivity and VRF-Lite for segmentation, while powering high-density UPOE-enabled endpoints.
Functions as a leaf switch in small-scale data centers, delivering multi-gig UPOE to servers and network appliances, and connecting to spine switches via 4 × 10 Gbps SFP+ uplinks for low-latency East-West traffic.
