Traffic Monitor Requirements

Traffic monitors can be configured on the following types of routers and/or switches within your enterprise network.

For best results, we recommend you do not use Network Address Translation (NAT) between your traffic monitors and your forwarders, as NAT can obscure identification of the devices on your enterprise network, thus hampering Traffic Insights’ ability to pinpoint issues.

Supported Cisco Devices

Supported Cisco devices for NetFlow v9 and IPFIX are:

Routers

• ISR1K

• ISR4K

• CSR1K

• ASR1K

• Cat8K

Switches

• Cat9K for switches

Meraki

• MX devices

These devices don’t have to be capable of running a ThousandEyes Enterprise Agent. They only have to be able to send network flows to the Enterprise Agent that is acting as a forwarder.

Supported Non-Cisco Devices

Any device that supports the standard NetFlow v9 or IPFIX with the minimum fields can send network flow data to Traffic Insights. See Minimum Fields Required for information about the minimum fields.
