Verify the GRE/UDP tunnel between vSCOUT and vSTREAM

Introduction

vSCOUT does not produce session detail records nor does it store packets . However, you can still gain access to session details and packet-level data by configuring traffic forwarding from vSCOUT to vSTREAM or InfiniStream interface managed by the same nGeniusONE server. Forwarded packets can be stripped out of the tunnel and made availabe for packet-level analysis on the receiving interface.  

This procedure allows you to verify the existance of the tunnel i.e. packets being transported between vSCOUT and vSTREAM

 

Solution

On NGeniusONE Server module Device Settings, write down the IP address of the interface that terminates the tunnel.

 

On vSTREAM

Login to vSTREAM CLI (ssh) as root

Type ip addr and write down the name of the interface that has the IP address from step 1

ip addr 

and note the interface that has the IP address from step 1
