Product overview Product highlights • Highest wireless scale for Wi-Fi 6 and 802.11ac Wave 2 access points supported on a single switch with select models. • Catalyst 9300 and Catalyst 9300L/LM models are based on the Cisco UADP 2.0 ASIC with programmable pipeline and micro-engine capabilities, along with template-based, configurable allocation of Layer 2 and Layer 3 forwarding, access control lists (ACLs), and quality-of-service (QoS) entries. • Catalyst 9300X models are based on UADP 2.0sec ASIC, which adds line-rate support for crypto, including 100G hardware-based IPsec. • x86 CPU complex with 8 GB memory, 16 GB of flash, and an external USB 3.0 SSD pluggable storage slot (delivering up to 240 GB of storage with an optional SSD drive) to host containers. Catalyst 9300X models support 16 GB of memory. • USB 2.0 slot to load system images and set configurations. • Up to 1 Tbps of local stackable switching bandwidth with the Catalyst 9300X models. • Deeper buffer and higher scale model options for rich multimedia content delivery applications. • Flexible and dense uplink offerings with 100G, 40G, 25G, Multigigabit, 10G, and 1G as fixed or modular uplinks. • Easy transition from 40G to 100G and 10G to 25G with dual-rate optics. • Flexible downlink options with 25G, 10G and 1G copper and fiber as well as the densest Multigigabit links. • With a mix of copper (1G up to 10G) and fiber (1G up to 25G) supported in a single stack, multiple flexible deployment scenarios are enabled, including 2-tier, 3-tier, and hybrid architectures. • Leading Power over Ethernet (PoE) capabilities with up to 384 ports of PoE per stack, PoE+, and 288 ports of high-density IEEE 802.3bt-90W UPOE+ and 60W Cisco UPOE®. • Intelligent power management with Cisco StackPower technology, providing power stacking among members for power redundancy. StackPower pools the power supplies across the stack to be used for redundancy and supplemental power purposes. • Line-rate, hardware-based Flexible NetFlow (FNF), delivering flow collection of up to 128,000 flows with select models. • IPv6 support in hardware, providing wire-rate forwarding for IPv6 networks. • Dual-stack support for IPv4/IPv6 and dynamic hardware forwarding table allocations, for ease of IPv4-to-IPv6 migration.
