Solarwinds & Cisco Live! Barcelona
Join us from the 29th of January to the 2nd of February at Cisco Live 2018 in Barcelona, where we will continue to show how monitoring the network with SolarWinds will keep you ahead of the game. At our booth (WEP 1A), we will demonstrate how SolarWinds network solutions can help. As a bonus, we are also hosting a pre-event webinar - Blame the Network, Hybrid IT Edition with our SolarWinds Head Geek™, Patrick Hubbard on January 24th - GMT (UTC+0): 10:00 a.m. to 11:00 a.m. There's still time to RSVP.

NTA Getting Started Home

Updated: March 14, 2017

SolarWinds NTA collects and monitors interface-level flow data, and helps you identify consumers of bandwidth. Flow data comes to SolarWinds NTA using one of many protocols.

Selectively specifying monitored protocols can reduce the amount of NetFlow traffic that SolarWinds NTA processes, which improves performance. Specified protocols depend on the device type, as each device supports different types of protocols. Check your vendor's documentation to determine the correct protocols.

Difference between sampled and non-sampled flow:

  • Sampled flow: Collects less data and provides only a sample. This prevents the network from overloading.
  • Non-sampled flow: Collects all data.

SolarWinds NTA supports these flow-enabled devices:

Flow Supported Versions Sampled Flow Support

v1, v5 and v9

NetFlow version 9 is configured the same as NetFlow version 5, but uses a predefined template that is exported in separate flows. Flexible NetFlow is based on NetFlow version 9, but the fields are defined during configuration.

NetFlow v9 must have an appropriate template with all required fields.

v5 and v9

Some devices using IOS versions export flows without specifying that it is being sampled. SolarWinds NTA processes these flows as unsampled.
sFlow v2, v4, and v5 Supported
J-Flow Supported Supported

Some devices using JunOS versions export flows without specifying that it is being sampled. SolarWinds NTA processes these flows as unsampled.

Supports IPFIX generated by ESX 5.1 and later, for IPv4 traffic.

NetStream v5 and v9 Supported
NetFlow Lite

Supported on the following devices:

  • Cisco Catalyst 2960-X
  • Cisco Catalyst 2960-XR
  • Cisco Catalyst 3560-CX
  • Cisco Catalyst 2960-CX
Cisco Wireless Controller NetFlow

Supported on the following devices with the ipv4_client_app_flow_record template:

  • Cisco 2504 WLC
  • Cisco 5508 WLC
  • Cisco 5520 WLC
  • Cisco Flex 7510 WLC
  • Cisco 8510 WLC
