Configure Solarwinds Network Traffic Analyzer

Do you want to find out who is the culprit on your network chewing up valuable bandwidth and killing your network admin's reputation:


Go here and download NTA

To configure via GUI/ web on an ASA click here

Next go here to configure your cisco hardware to talk or read below:

(config)#ip flow-export ver
(config)#ip flow-export version 5
(config)#ip flow
(config)#ip flow-expo
(config)#ip flow-export destion
(config)#ip flow-export desti
(config)#ip flow-export destination [your NTA flow server] 2055
(config)#int vlan 3
(config-if)#ip flow egress
(config-if)#ip flow ingress
(config-if)#ip route-ca
(config-if)#ip route-cache flow
(config-if)#exit
(config)#wr mem

below I got some really good information from Jake over there at ploxer:


Setting up NetFlow Lite on the 2960x:
!
! step 1: create a flow record
flow record flows
match datalink mac source address input
match datalink mac destination address input
match ipv4 tos
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
collect transport tcp flags
collect interface input
collect flow sampler
! below I specified ‘long’ because the 2960x supports 64 bit counters
collect counter bytes long
collect counter packets long
collect timestamp sys-uptime first
collect timestamp sys-uptime last
!
!
! step 2: create a flow exporter
flow exporter export-to-inside
description flexible NF v9
destination 10.1.1.1
source Vlan7
transport udp 2055
template data timeout 60
!
! lets export some cool option templates
option interface-table
option exporter-stats
option sampler-table
!
!
! step 3: create a flow monitor
flow monitor nftest
record flows
exporter export-to-inside
cache timeout active 60
statistics packet protocol
!
! Below was used for the deterministic sampling configuration
! that I didn’t like because of the 4 interface limitation
! sampler full
! mode deterministic 1 out-of 32
!
! below is the random sampler configuration that I replaced
! the above with.
sampler my-random-sampler
mode random 1 out-of 100
!
!
!
! step 4: apply the flow monitor ‘nftest’ to each interface with
! the defined sampler ‘my-random-sampler’
! input is for ingress.  Egress was not supported in this release…
interface GigabitEthernet1/0/1
ip flow monitor nftest sampler my-random-sampler input
!
interface GigabitEthernet1/0/2
ip flow monitor nftest sampler my-random-sampler input
!
interface GigabitEthernet1/0/3
ip flow monitor nftest sampler my-random-sampler input
!
interface GigabitEthernet1/0/4
ip flow monitor nftest sampler my-random-sampler input
!

Error: NetFlowService inaccessible. Verify that service is 'Started

1) you have licensing issue, e.g. NTA licensce doesn't match volume of NPM license; Fix: obtain correct license



2) you have changed IP address/hostname of Orion server or migrated to another server keeping old DB; Fix: Either contact support to solve this, or go to Orion Settings > Details > Polling Engines > check that you have two primary polling engines > delete the old one. Then go to NetFlow summary view > NetFlow services resource > Edit > Delete the old NetFlow service.



3) make sure you have same time and timezone on both Orion and SQL server



4) your service might have some real issues which keeps it crashing, so if previous reasons are not your case then please contact support.
