Overview

This article provides an example NTA configuration for Cisco 2900 series routers.

\Note: SolarWinds does not provide support for device configuration. It is recommended that you open a case with the device vendor.

Environment

All NTA versions

Detail

Configure terminal

router-2960(config)#interface FastEthernet 0/1

Note: The layer 3 interfaces. Configure on all interfaces interested in collecting Netflow data.

router-2960(config-if)#ip route-cache flow or ip flow ingress

router-2960(config-if)#exit

router-2960(config)#ip flow-export destination x.x.x.x 2055 ( port used to export flow

Note: x.x.x.x is the Orion Server IP Address and 2055 is the collection port on the NPM server. You can verify the port by going to Setting > NTA Settings; Scroll down to the NetFlow Collector Services and look under COLLECTIONS PORT(S).

router-2960(config)#ip flow-export source FastEthernet 0/1

Note: This should be the interface that is configured with the IP address that the device is being monitored in Orion by.

router-2960(config)#ip flow-cache timeout active 1
router-2960(config)#ip flow-cache timeout inactive 15

Note: The two commands above will ensure that you are not receiving any data peaks that exceed the bandwidth of the circuit.
