Cisco Catalyst 9300 Series Switches Overview

What are the Cisco Catalyst 9300 Series Switches?

The Cisco Catalyst 9300 Series Switches are the next generation of

enterprise-class stackable access-layer switches

that are part of the new Cisco Catalyst 9000 Family. These switches also support full IEEE 802.3at PoE+, UPoE, modular and field-replaceable network modules, redundant fans, and power supplies.

In addition, the Cisco Catalyst 9300-based models support a variety of uplink modules for both copper and fiber uplink support. These models add even more flexibility to the interface choices that you can make in a single Cisco Catalyst 9300 Switch or in a stack of Cisco Catalyst 9300 Switches.

Can I stack Cisco Catalyst 9300 with the 3850?





These switches do not stack together. Features are packaged differently between these platforms, they use different CPU architectures, and the platforms do not have the same scaling, making stacking with them impossible.

Are the network modules shared between the Cisco Catalyst 9300 and 9500?





No, the network modules are not shared between the Catalyst 9300 and 9500 because the ASIC, depth, and form factors are different for these product lines.

Can the Cisco Catalyst 9300 act as a wired switch?





The Catalyst 9300 switch provides connectivity for wired endpoints and wireless endpoints by connecting wireless access points. With the SD-Access architecture, the wired and wireless endpoints gets the same experience.

What are the supported uplink modules in the Cisco Catalyst 9300?





The Catalyst 9300 supports the following new uplink modules. All modules are supported across all 9300 platforms:

• 4 x 1 Gigabit Ethernet network module
• 4 x 1, 2.5, 5, or 10 Gigabit Ethernet network module
• 8 x 10 Gigabit Ethernet network module
• 2 x 40 Gigabit Ethernet network module

Are the uplinks between the Cisco Catalyst 9300 and the 3850 interchangeable?

All existing 3850 uplink modules may be used in the Catalyst 9300 platforms. However, the new 9300 uplinks modules are not supported on the 3850 platforms.

What about service modules for the Cisco Catalyst 9300?

There are no service modules for the Catalyst 9300. All functions are embedded into the platform.

Where can I purchase an SSD module for the Cisco Catalyst 9300?

Cisco-approved SSD modules will be made available in the future.

What management ports are available on the Cisco Catalyst 9300?

This switch comes with a 10/100/1000 Ethernet dedicated management port on the backside of the switch right above the console port. This port is in a separate VRF instance called “Mgmt-vrf” in order to segment the management traffic from the global routing table of the switch.

Can I use both console ports on Cisco Catalyst 9300 simultaneously?

No. When you use the USB console, the RJ-45 console receives the output of the USB console as well. This design allows the administrator to see when the USB console port is in use. This capability is useful for remote administrators.

Does the Cisco Catalyst 9300 Switch support auto-baud on the console port?

No.

What type of airflow do the Cisco Catalyst 9300 Switches support?

The airflow on the Catalyst 9300 is “front and sides” to back airflow.

What pluggable transceiver modules do the Cisco Catalyst 9300 Switches support?

Built for Security, IoT, Mobility, and Cloud

The Cisco® Catalyst® 9300 Series Switches are Cisco’s lead stackable enterprise switching platform built for security, IoT, mobility, and cloud. They are the next generation of the industry’s most widely deployed switching platform. The Catalyst 9300 Series switches form the foundational building block for Software-Defined Access (SD-Access), Cisco’s lead enterprise architecture. At 480 Gbps, they are the industry’s highest-density stacking bandwidth solution with the most flexible uplink architecture. The Catalyst 9300 Series is the first optimized platform for high-density 802.11ac Wave2. It sets new maximums for network scale. These switches are also ready for the future, with an x86 CPU architecture and more memory, enabling them to host containers and run third-party applications and scripts natively within the switch.

The Catalyst 9300 Series is designed for Cisco StackWise® virtual technology, providing flexible deployment with support for nonstop forwarding with stateful switchover (NSF/SSO), for the most resilient architecture in a stackable sub-50-ms solution. The highly resilient and efficient power architecture features Cisco StackPower®, which delivers high-density Cisco Universal Power Over Ethernet (Cisco UPOE®) and Power over Ethernet Plus (PoE+) ports. The switches are based on the Cisco Unified Access™ Data Plane 2.0 (UADP) 2.0 architecture which not only protects your investment but also allows a larger scale and higher throughput. A modern operating system, open Cisco IOS XE with programmability offers advanced security capabilities and Internet of Things (IoT) convergence.

The foundation of Software-Defined Access

Advanced persistent security threats. The exponential growth of Internet of Things (IoT) devices. Mobility everywhere. Cloud adoption. All of these require a network fabric that integrates advanced hardware and software innovations to automate, secure, and simplify customer networks. The goal of this network fabric is to enable customer revenue growth by accelerating the rollout of business services.

The Cisco Digital Network Architecture (Cisco DNA™) with SD-Access is the network fabric that powers business. It is an open and extensible, software-driven architecture that accelerates and simplifies your enterprise network operations. The programmable architecture frees your IT staff from time-consuming, repetitive network configuration tasks so they can focus instead on innovation that positively transforms your business. SD-Access enables policy-based automation from edge to cloud with foundational capabilities. These include:

• Simplified device deployment
• Unified management of wired and wireless networks
