# Catalyst Switches

ThousandEyes supports installing Enterprise Agents on Cisco Catalyst switches using either Cisco application hosting or the Cisco Catalyst Center. This reference article provides a brief overview of Cisco application hosting, licensing information, system requirements for each supported Cisco Catalyst switch, as well as links to supported installation methods.

Please review the tables below before beginning the installation and setup process.

## Application Hosting Overview

To support application hosting capabilities on Cisco Catalyst switches, the switch provides hardware resources where applications can reside and execute. Cisco IOS XE reserves dedicated memory and CPU resources for application hosting to provide a separate execution space for user applications, without compromising the integrity and performance of the switch.

For more information on Cisco application hosting, see [Application Hosting](https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/prog/configuration/1718/b-1718-programmability-cg/m_1718_prog_thousandeyes.html).

## Licensing and Entitlements

A Cisco Switching Advantage license is required for each Enterprise Agent installed on a Cisco Catalyst 9k series switch. Customers are entitled to 22 units per DNA license. For more information, see [About Units](https://docs.thousandeyes.com/product-documentation/user-management/usage-and-billing/about-usage-units).
