# Cisco Enterprise NFV Infrastructure Software

ThousandEyes supports installing Enterprise Agents on supported Cisco Catalyst routers and UCS-C rack servers using Cisco Enterprise Network Functions Virtualization Infrastructure Software (NFVIS).

This article outlines the system requirements and supported devices for Cisco NFVIS.

## Overview

ThousandEyes Enterprise Agents can be installed as a container within your NFVIS environment, allowing you to leverage ThousandEyes monitoring and testing capabilities for end-to-end visibility into the performance of the underlying network infrastructure.

For more information about Cisco NFVIS, see here: [Cisco NFVIS](https://www.cisco.com/c/en/us/products/routers/enterprise-nfv-infrastructure-software/index.html).

### Install Enterprise Agents on Cisco Routers using NFVIS and the ThousandEyes CLI

To install a ThousandEyes Enterprise Agent on NFVIS using the CLI:

1. Configure the Docker image registration details. An example configuration is shown below. Ensure you replace the `src` URL with the URL provided in the **Add New Enterprise Agent** dialog:

   ```
   vm_lifecycle images image thousandeyes-enterprise-agent
    src https://downloads.thousandeyes.com/enterprise-agent/thousandeyes-enterprise-agent-VERSION-nfvis.docker
    locator vim_id container
    properties property low_latency
     value false
    !
    properties property placement
     value datastore1
    !
    properties property vnf_type
     value THOUSANDEYES
    !
    
   !
   ```
2. Configure the resource details as a flavor:

   ```
   vm_lifecycle flavors flavor thousandeyes-flavor vcpus 2 memory_mb 2048 root_disk_mb 20480
   !
   ```
3. Configure the ThousandEyes Enterprise Agent container deployment details, replacing `ACCOUNT_GROUP_TOKEN` with your account group token:

   ```
   vm_lifecycle tenants tenant admin
    deployments deployment TE_DEMO
     vm_group TE_DEMO
      vim_vm_name  TE_DEMO
      locator vim_id container
      image       thousandeyes-enterprise-agent
      flavor      thousandeyes-flavor
      bootup_time -1
      config_data configuration bootstrap_config
       data            "{ \"env_variables\" : { \"TEAGENT_ACCOUNT_TOKEN\" : \"${TEAGENT_ACCOUNT_TOKEN}\", \"TEAGENT_INET\" : \"4\"} }"
       template_engine VELOCITY
       variable TEAGENT_ACCOUNT_TOKEN
        val [ ACCOUNT_GROUP_TOKEN ]
       !
     !
    !
   !
   ```
4. Commit the configurations.
