Looking to compare latest NPM features with previous versions of NPM?
The NPM new feature summary offers a comparison of new features and improvements offered with this release.
Exporting flows on some Cisco devices (for example, the 4500 series, with Supervisor 7) requires using Flexible NetFlow. This configuration example successfully exports flows from a Cisco 4507 with Supervisor 7:
flow record ipv4 ! match ipv4 tos match ipv4 protocol match ipv4 source address match ipv4 destination address match transport source-port match transport destination-port match interface input collect interface output collect counter bytes collect counter packets flow exporter NetFlow-to-Orion destination 10.10.10.10 source vlan254 transport udp 2055 export-protocol netflow-v5 flow monitor NetFlow-Monitor description Original Netflow captures record ipv4 exporter NetFlow-to-Orion cache timeout inact 10 cache timeout act 60 vlan configuration 666 ip flow monitor NetFlow-Monitor input
The setting "cache timeout act 60" can be modified to lower values, but doing so might add more stress to the device due to higher number of flows sent. Also, NetFlow caches flow data for 1 minute before storing the data in the NTA Flow Storage Database.
flow exporter destination and
transport udp values must reflect the IP address and port (2055) of your SolarWinds NPM server.
SolarWinds NTA supports NetFlow version 5 and version 9. For more information about NetFlow version 5 or 9, see your Cisco router documentation or the Cisco website at www.cisco.com.
