Cisco Catalyst 9300 Series Switches

Product Highlights

● Highest wireless scale with Wave 2 access points supported on a single switch with select models
● UADP 2.0 Application-Specific Integrated Circuit (ASIC) with programmable pipeline and microengine capabilities, along with template-based, configurable allocation of Layer 2 and Layer 3 forwarding, Access Control Lists (ACLs), and Quality of Service (QoS) entries
● x86 CPU complex with 8-GB memory, and 16 GB of flash and external USB 3.0 SSD pluggable storage slot (delivering 120GB of storage with an option SSD drive) to host containers
● USB 2.0 slot to load system images and set configurations
● Up to 480 Gbps of local stackable switching bandwidth
● Flexible and dense uplink offerings with 1G, Multigigabit, 10G, 25G, and 40G
● Flexible downlink options with 1G and Multigigabit links
● Leading PoE capabilities with up to 384 ports of PoE per stack, 60W Cisco UPOE, and PoE+
● Intelligent Power Management with Cisco StackPower technology, providing power stacking among members for power redundancy
● Line-rate, hardware-based Flexible NetFlow (FNF), delivering flow collection of up to 64,000 flows
● 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
● IEEE 802.1ba AV Bridging (AVB) built in to provide a better audio and video experience through improved time synchronization and QoS
● Precision Time Protocol (PTP; IEEE 1588v2) provides accurate clock synchronization with sub-microsecond accuracy making it suitable for distribution and synchronization of time and frequency over network
● Cisco IOS XE, a modern operating system for the enterprise with support for model-driven programmability including NETCONF, RESTCONF, YANG, on-box Python scripting, streaming telemetry, container-based

application hosting, and patching for critical bug fixes. The OS also has built-in defenses to protect against runtime attacks
● SD-Access: The Cisco Catalyst 9300 Series Switches form the foundational building block for SD-Access, Cisco’s lead enterprise architecture:
◦ Policy-based automation from edge to cloud
◦ Simplified segmentation and micro-segmentation, with predictable performance and scalability
◦ Automation through the Cisco Application Policy Infrastructure Controller Enterprise Module (APIC-EM)
◦ Policy handled through the Cisco Identity Services Engine (ISE)
◦ Network assurance provided through the Network Data Platform
◦ Faster launch of new business services and significantly improved issue resolution time
● SD-Access Embedded Wireless: The Cisco Catalyst 9800 Wireless Controller Software package can be installed on Cisco Catalyst 9300 series switches to enable wireless controller functionality for distributed branches and small campuses. Once installed Wireless Controller running on Catalyst 9300 can support up-to 200 APs and 4000 Clients. Maximum two Wireless Controllers can be enabled per site on two different Catalyst 9300 which will increase to scale to 400 APs and 8000 Wireless Clients. C9800 Wireless Controller Software Package will enable Wireless Functionality only for SD-Access deployments with two supported topologies:
◦ C9800 Wireless Software Package can be enabled on C9300 series switches functioning as Co-Located Border and Control Plane
◦ C9800 Wireless Software Package can be enabled on C9300 series switches functioning as Fabric in a Box
● Plug and Play (PnP) enabled: A simple, secure, unified, and integrated offering to ease new branch or campus device rollouts or updates to an existing network
● Advanced security
◦ Encrypted Traffic Analytics (ETA): You benefit from the power of machine learning to identify and take actions toward threats or anomalies in your network, including malware detection in encrypted traffic (without decryption) and distributed anomaly detection
◦ Support for AES-256 with the powerful MACsec 256-bit encryption algorithm available on all models
◦ Trustworthy systems: Hardware anchored Secure Boot and Secure Unique Device Identification (SUDI) support for Plug and Play, to verify the identity of the hardware and software

Table 1.        Product Family Configurations

Cisco Catalyst 9300 Series switches (C9300X and C9300 SKUs) support optional network modules for uplink ports (Figure 2). These field-replaceable network modules with 25G and 40G speeds in the Cisco Catalyst 9300 Series enable greater architectural flexibility and infrastructure investment protection by allowing a nondisruptive migration from 10G to 25G and beyond. The default switch configuration does not include the network module. When you purchase the switch, you can choose from the network modules described in Table 2.

^*C9300X-NM-4C is compatible only with C9300X-48HX, C9300X-48TX and C9300X-24Y models

Please note: Catalyst 3850 and Catalyst 9300 network modules are supported on the Catalyst 9300 models. Catalyst 9300X network modules are only supported on the Catalyst 9300X models.

Cisco Catalyst 9300 Series switches support dual redundant power supplies. The switches ship with one power supply by default, and the second power supply can be purchased when the switch is ordered or at a later time. If only one power supply is installed, it should always be in power supply bay #1. The switches also ship with three field-replaceable fans. Power Supplies are common across the Catalyst 9300 Series.
