The Cisco C9300L-24T-4G-E is a fixed-uplink, stackable enterprise access switch in the Catalyst 9300L line. It provides 24 × 1 Gbps copper (RJ-45) ports and 4 fixed 1 Gbps SFP uplink ports (for fiber uplinks) for aggregation or upstream connectivity.
The “E” in the model denotes that it comes with the Network Essentials software license by default.
It supports layering of switching and routing features (Layer 2 + limited Layer 3) and is designed for deployment in enterprise campus access networks.
The switch is stackable via StackWise-320 (for C9300L class) so multiple units can be managed and operated as a single logical switch.
Fixed Port Configuration: 24 × 1G RJ-45 ports + 4 × 1G SFP uplinks (non-modular)
Switching Capacity & Forwarding Rate:
• Switching capacity: ~56 Gbps
• Forwarding rate: ~40.66 Mpps (for 64-byte packets)
Stacking: StackWise-320 support (for C9300L fixed uplink switches)
Power & Redundancy:
• Standard single AC power supply (715W AC default)
• Dual (redundant) power supply capability (you can install a second PSU for redundancy)
Layer 2 / VLAN Features: VLANs (802.1Q), private VLANs, link aggregation (LACP), Spanning Tree variants (STP, RSTP, MST), port security, QoS, storm control, etc. (standard features in the Catalyst 9300 family)
Layer 3 / Routing: Static IP routing, RIP, limited routing capabilities are supported depending on license / software image.
Reliability & Resiliency: Features like errdisable recovery, cross-stack EtherChannel, extended fast software upgrade, redundant fans in modular models (though fixed uplink models have simpler fan arrangements)
Security, Programmability & Modern Features: Support for Trust Anchor, secure boot, hardware-based device authentication, support for APIs (NETCONF, RESTCONF, gNMI), integration with Cisco DNA, SD-Access readiness, automation features, etc.
