Simple Jflow config fails check out

‎05-16-2017 01:15 PM

Hello all....

 

First time configuring JUNOS for netflow\jflow. Found a simple Juniper KB config sample ...which is exactly the config found on SolarWinds site....which is my flow collector. Switch is an EX 4300-32F

 

So,,,,here's my config - want to monitor the flows on an AE interface... 

 

and the check out fails and I'm not sure why. I tried to raise the rate to 1000.... sampling only input..same results.

 

Appreciate the help ! 

 

commit check
error: Check-out pass for Traffic sampling control process (/usr/sbin/sampled) dumped core (0x8b)
error: configuration check-out failed

 

 

set interfaces ae0 unit 0 family inet sampling input output

set forwarding-options sampling input rate 100   (1 out of 100 packets is sampled)

set forwarding-options sampling family inet output flow-server 10.1.2.20 port 2055 version 5

 

root@Myl_Core_1# show | compare
[edit interfaces ae0 unit 0 family inet]
+ sampling {
+ input;
+ output;
+ }
[edit forwarding-options]
+ sampling {
+ input {
+ rate 100;
+ }
+ family inet {
+ output {
+ flow-server 10.1.2.20 {
+ port 2055;
+ version 5;
+ }
+ }
+ }
+ }

Hello,

Please include the link to KB in order for us to see what You are actually referring to.

Anyway - Your config is for Netflow v5.

Juniper EX switches do NOT support Netflow at all (not v5, not v8, not v9, not IPFIX)  - only Sflow.

Example Sflow config is here

Did not relaize that! That would explain the check out failure I suppose! )

 

This was the Solarwinds article I was refereing to - which links to a couple Juniper KBs

 

Anyway...I'll proceeed with SFLow-- and post back if have more troubles -- thanks Alex
