The Highly Scalable Cisco Catalyst 9300 Series Chassis Switch

by Darin Knobbe, on May 13, 2021 2:10:29 PM

Cisco announces the Catalyst 9300 Series Chassis Switch as the new generation fixed access Power over Ethernet (PoE) and Non-PoE switch built for security, IoT, and the cloud. In this article, we will find out the inside scoop on the Cisco Catalyst 9300 Series Switches.

A Brief Breakdown of the Catalyst 9300 Series Switches

The Catalyst 9300 Series is a stackable enterprise switching platform that is built for security, IoT, mobility, and the Cloud and is optimized for speeds up to 10G copper and 10/25G fiber. The Catalyst 9300 switches form the foundational building blocks for Cisco DNA and Software-defined Access – Cisco's leading enterprise architecture. These switches are the industry's first optimized platform for Wi-Fi 6 and 802.11ac Wave 2, with support for 1G/2.5G/5G/10G Multigigabit and dual-rate 25G/10G downlinks, 10G multigigabit, 100G/40G/25G/10G/1G uplinks, 90W Cisco UPOE+, Cisco UPOE, and PoE+.

The newest additions to the series are the 9300X 10/25G fiber switches. The 9300X models are the fixed access replacement for the Catalyst 3850XS series offering 1 Tb stacking bandwidth with 100G uplink options, enabling flexible deployments at the Access Layer.

Cisco Catalyst 9300 Series Features and Benefits

The Cisco Catalyst 9300 Series consists of fixed and modular uplink models with different port speeds and port densities to meet the ever-increasing performance of enterprise campus environments. Additionally, it provides an architectural foundation for next-generation hardware features and scalability. Here are a few of the features and benefits of the 9300 Series.

  • Provides support for the highest density of 90W UPOE+ and Wi-Fi 6 and 802.11ac Wave 2 access points, like the Cisco Catalyst 9100 Series.
  • Includes a native Docker container and enhanced application hosting supporting ThousandEyes Enterprise Agents and DNA Spaces onboard, Audio Video Bridging (AVB), and Catalyst 9800 Series embedded wireless controller support.
  • Offers the most flexible uplink architecture with fixed 1-Gbps and 10-Gbps models (C9300L), as well as modular uplink models (C9300) with 1-Gbps, Multigigabit, 10-Gbps, 25-Gbps, and 40-Gbps options and high performance (C9300X) with 1-Gbps, Multigigabit, 10-Gbps, 25-Gbps, 40-Gbps, and 100G options.
  • Offers a choice of 25-Gbps/10-Gbps/1-Gbps fiber, Multigigabit (including 1, 2.5, 5, and 10 Gbps), 5-Gbps, 2.5-Gbps, 1-Gbps copper Ethernet switch models with up to 400-Gbps uplink bandwidth, and the industry-leading 1-Tbps stacking bandwidth solution.
  • StackWise-480 technology for stacking up to 12 units that act as a single platform, with support for the best NSF and SSO resiliency architecture for a stackable solution (sub-50 ms).
  • Only switching platform in the industry with front- and back-panel stacking support, optimizing it for a variety of deployments.
  • Protected by the E-LLW.

The Cisco Catalyst 9000 family of switches introduces a new and simplified licensing package in base and add-on licenses.

The perpetual licensing package includes the Network Essentials and Network Advantage licensing options tied to the hardware. Between them, the base licensing packages cover switching fundamentals, management automation, troubleshooting, and advanced switching features. These network licenses are perpetual.

The subscription licensing package includes the Cisco DNA Essentials, Cisco DNA Advantage options, and Cisco DNA Premier. In addition to on-box capabilities, the features available with this package provide Cisco innovations on the switch and Cisco DNA Center.

Cisco DNA subscription licenses are mandatory at the time of configuration. With Cisco DNA software licenses, customers receive embedded SWSS – which covers 24x7x365 Cisco Technical Assistance Center (TAC) support, software release updates, advanced support analytics, and designated service management. This is valid only for the Cisco DNA software subscription stacks (Cisco DNA Essentials, Advantage, and Premier).
