Cisco C9300‑48T‑A Description
The Cisco Catalyst C9300‑48T‑A is part of Cisco’s flagship Catalyst 9000 Series, engineered for secure, high‑performance enterprise networking. With 48 Gigabit Ethernet ports, this switch is ideal for high‑density access layer deployments in offices, campuses, and data centers where reliability, manageability, and scalability are essential.
Powered by Cisco IOS XE software, the C9300‑48T‑A enables advanced networking capabilities such as segment routing, flexible NetFlow, multicast routing, and Layer 3 services. Its StackWise‑480 technology allows up to nine switches to be interconnected into a single logical unit, simplifying management, enhancing redundancy, and scaling network performance without complexity.
Security is built into every level of the switch, with features like MACsec encryption, 802.1X authentication, and policy‑based access control (ACLs). Combined with Cisco DNA Center integration, the C9300‑48T‑A supports software‑defined access (SD‑Access) and advanced automation for accelerated deployments and consistent policy enforcement.
Advanced Quality of Service (QoS) ensures traffic prioritization for voice, video, and mission‑critical applications — helping maintain service levels even under high load. Support for exported telemetry and analytics allows network teams to gain deeper visibility and faster troubleshooting.
