The Cisco Catalyst 9300-48S-E is a high-density, stackable Layer 3 fiber switch designed for enterprise aggregation, campus backbones, and data center ToR deployments. It offers 48 x 1G SFP fiber ports and a modular uplink slot, delivering long-distance, EMI-resistant connectivity. The "-E" suffix denotes the Cisco DNA Network Essentials license for foundational automation and security.
48 x 1G SFP Ports: Full fiber downlink configuration for pure data switching, supporting single-mode/multimode transceivers.
No PoE: Optimized for non-PoE, fiber-heavy environments focused on aggregation and long-haul links.
Modular Uplink Bay: 1 x hot-swappable slot supporting 10G/25G/40G modules (e.g., C9300-NM-2Q, C9300X-NM-8Y) for scalable uplinks.
StackWise-480: Stack up to 8 switches with 480 Gbps stacking bandwidth for unified management and N+1 redundancy.
StackPower: Power supply sharing across the stack enhances availability.
Non-Stop Forwarding (NSF/SSO): Sub-50ms failover ensures zero downtime during stack transitions.
UADP 2.0 ASIC: Wire-speed Layer 2/3 switching with robust QoS.
Security: MACsec-256 encryption, Secure Boot, and ACLs protect data in transit.
Switching Capacity: 256 Gbps (single unit) / 736 Gbps (stacked).
Forwarding Rate: 190.47 Mpps (single unit) / 547.62 Mpps (stacked).
Cisco DNA Essentials: Automation, telemetry, and monitoring via Cisco DNA Center.
Cisco IOS XE: Programmable OS with NETCONF/YANG for model-driven management.
Flexible NetFlow (FNF): Deep traffic visibility for monitoring and threat detection.
