Cisco: Catalyst 9400 Series Switches Review

The Cisco Catalyst 9400 Switch Series is a next-generation line of modular access switches designed for flexibility, security, Internet of Things (IoT), and smart buildings.

The series is an enterprise switching platform for high availability, with modular core/distribution/access switches designed to help bridge the network with the business and the business with the customers.

Cisco offers three main types of models for the Catalyst 9400 series switches based on the number of slots: 10-slot, 7-slot, or 4-slot Catalyst 9400.

Cisco and the switch market

Cisco had 49.9% of the global Ethernet switch market share in Q3 2020, according to Statista.

Since 2013, Cisco has not seen a market share lower than 47.2% in the second quarter of 2020.

The company’s revenue in 2021 was $49.8 billion, with net income of $10.6 billion.


Cisco Catalyst 9400 Series Switches have many advanced capabilities designed to provide high speed and capacity, high density, and availability to help protect businesses before, during, and after an attack.

The series has some useful features, such as supporting up to 9.6 Tbps, providing the latest 90-watt UPOE+ encryption, and MACsec 256, which helps reduce the attack surface and improve rapid threat containment.

Other features include:

IoT readiness

Cisco Catalyst 9400 Series Switches provide the segmentation, automation, and reliability needed to support the next generation of smart buildings and IoT without disruption, while limiting where IoT devices sit on the network. These switches offer up to 384 ports of Cisco UPOE, PoE+, and perpetual 100W PoE, enabling Cisco to deliver IoT convergence at scale.

End-to-end visibility

Cisco Catalyst 9400 Series Switches enable organizations to move to the cloud with confidence with the built-in network intelligence of Cisco ThousandEyes. Cisco simplifies, secures, and transforms the cloud environment from the network edge and delivers a digitally-ready approach that extends to where applications reside.

core technology

Cisco Catalyst 9400 Series Switches provide high density and high availability with hot patching, orderly insertion and removal, NSF/SSO, and redundant platinum-rated power supplies and fans. The switches also support advanced routing and infrastructure services.

Faster core, faster access

Cisco Catalyst 9400 Series Switches are designed to provide twice the speed and capacity of traditional switches, and the Cisco DNA Center simplifies IT operations. There is less operational risk as users plan and implement migration projects with Cisco services.

use cases

Cisco Catalyst 9400 Series Switches are used as a core switch and to interconnect data centers in the same city and in other cities.

University Health System Consortium

University HealthSystem Consortium is a hospital and healthcare provider that uses multiple Cisco Catalyst 9400 Series Switches for its data centers. The switches provide increased speed, stability, and security with enterprise-class wide area network (WAN) and (local area network) protocols and features.

Mark McCully, senior network administrator for the University HealthSystem Consortium, says the switches are “a strong and secure network core for your business.”

“We take advantage of the APIs that the Cisco Catalyst 9400 Series Switches make available to provision resources on the core switches for different pieces of whatever infrastructure we’re running as code scripts,” says McCully.

“Using automation to build infrastructure resources allows us to deliver new environments to our application development team much faster (with less chance of user error or build issues).”

EBSCO Industries

EBSCO Industries is a leading provider of discovery services, databases, and various information resources and services to libraries around the world. The company uses Cisco Catalyst 9400 Series Switches as a collapsed core design in all of its remote offices.

Christopher Hall, senior director of employee support services at EBSCO Industries, says that the Cisco Catalyst 9400 Series switches “allow us to meet all the requirements of a small to medium office without having too much equipment. Security and management are there along with speed.”

He says no other switch can meet as many diverse needs as the Cisco Catalyst 9400 Series Switches, and it’s relatively easy to find people who can configure, run, and operate them.

keep going

Continuant is a telecommunications service provider in Fife, Washington that uses Cisco Catalyst 9400 Series switches for its access layer switches. They are satisfied that the switches can handle the number of users and traffic as needed.

Benjamin Salmond, Cisco Network Engineer at Continuant, says, “These switches handle a large number of users with ease, especially with dual 40G uplinks.”

“I find the Catalyst IOS setup very simple and easy to teach others,” says Salmond. “For me, they’re great for access, distribution, and even the core of the campus architecture, depending on how much traffic is needed, like a collapsed core.”

Customer Reviews

The Cisco Catalyst 9400 Series Switches have an overall rating of 9.6 out of 10, based on TrustRadius Review. Based on the revision G2Cisco Catalyst switches have a very good rating of 4.6 out of 5.

Cisco Catalyst 9400 Series Switches mostly receive a rating of 5 out of 5, with a couple of models receiving 4.9, based on the Router switch review.


There is a wide variety of Cisco Catalyst 9400 series switch models, with prices ranging from about $60 for home office use to $85,000 for large enterprise hardware.
