Hello all,
Is there any way yo analyze the GTP V1 protocol flow in Ethereal?
I know that Ethereal support GTP V0 and V1 as well but I'm interested in the filter process for GTP V1. In GTP V0 is very easy to fiter a packet flow from a subscriber using the TID wich is composed of the IMSI user and the NSAPI. In GTP V1 instead, the packet flow is identified by two arguments: TEID User Plane and TEID Control Plane, which are chanching all time for differents PDP Context and differents sessions. Is there any analysis tool in Ethereal to analyze a complete GTP V1 packet flow based on those identifiers? I can identify the first packet (Create PDP Context Request) based on the IMSI user, but I have to filert manually the rest of the flow...... I would like to know if there is any automated process to do this.
Thank you very much in advance for your help,
Best regards,
Diego
