Cisco Catalyst C9300-24T-A – Enterprise-Grade Stackable Access Switch
The Cisco Catalyst C9300-24T-A is a 24-port Gigabit Ethernet data-only switch from Cisco’s flagship Catalyst 9300 Series, purpose-built for enterprise access layer deployments. Powered by Cisco’s UADP 2.0 ASIC and running Cisco IOS XE, it delivers a non-blocking switching capacity of 208 Gbps (expandable to 688 Gbps with stacking) along with a forwarding rate of 154.76 Mpps. Designed for campus networks, branch offices, and data centers, it combines advanced Layer 2/3 features with deep programmability and robust security. One modular uplink slot supports optional 1G, 10G, 25G, or 40G network modules, ensuring long-term investment protection.
Key Features & Benefits
24 x 10/100/1000 RJ-45 Ports (Data Only) – Provides wire-speed Gigabit Ethernet connectivity to end devices; the “T” model is strictly data-only with no PoE circuitry, ideal for server-side or uplink aggregation roles.
208 Gbps Non-Blocking Switching Capacity – Built on the Cisco UADP 2.0 ASIC, ensuring zero packet loss even under peak enterprise workloads, with up to 688 Gbps when stacked.
Cisco StackWise-480 Technology – Stack up to 8 switches as a single logical unit with 480 Gbps of stacking bandwidth for centralized management, resiliency, and simplified operations.
One Modular Uplink Slot – Supports field-replaceable network modules (1G/10G/25G/40G), allowing nondisruptive migration to higher-speed uplinks as network demands grow.
Cisco IOS XE with Full Programmability – Supports NETCONF, RESTCONF, YANG models, Python scripting, and streaming telemetry for complete network automation and integration with Cisco DNA Center.
Advanced Security Suite – Includes MACsec 256-bit encryption, Cisco TrustSec, Secure Boot, Control Plane Policing (CoPP), and hardware-anchored trust via Cisco Trust Anchor module.
SD-Access & Cisco DNA Center Ready – Fully compatible with Software-Defined Access for policy-based segmentation, automation, and network assurance in hybrid cloud environments.
Dual Redundant Power Supply Slots – Ships with one 350W AC power supply; a second PSU slot supports hot-swappable redundancy for maximum availability.
Large Routing & MAC Tables – Supports up to 32,000 MAC addresses, 32,000 IPv4 routes, and 16,000 IPv6 routes, handling the most complex enterprise topologies.
Application Hosting (IOx) – Dedicated CPU/memory resources allow hosting of Docker containers, ThousandEyes agents, and ASAc firewall directly on the switch.
