# Service Routers

ThousandEyes supports installing Enterprise Agents on Cisco Aggregation Services routers (ASR) and Integrated Services routers (ISR) using the command line interface (CLI) or the SD-WAN Manager.

This reference article provides a brief overview of the CLI and the SD-WAN manager, system requirements for each supported Cisco ASR and ISR device, as well as links to supported installation methods.

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

## SD-WAN Manager

ThousandEyes supports installing Enterprise Agents on Cisco Catalyst routers running in SD-WAN mode that are managed by SD-WAN Manager. For more information about SD-WAN Manager, see the [SD-WAN Manager Documentation](https://www.cisco.com/c/en/us/solutions/enterprise-networks/sd-wan/vmanage.html).

{% hint style="info" %}
vEdge routers must be added to the SD-WAN Manager inventory list before installation. For more information, see the [SD-WAN Manager Documentation](https://www.cisco.com/c/en/us/solutions/enterprise-networks/sd-wan/vmanage.html).
