# GPRS Tunnelling Protocol (GTP)
|
|
|
|
|
|
Used on:
|
|
|
|
|
|
- the Gn and Gp interfaces of the General Packet Radio Service (GPRS);
|
|
|
- the Iu, Gn and Gp interfaces of the UMTS system.
|
|
|
|
|
|
Specified in 3GPP TS 29.060
|
|
|

|
## History
|
|
|
|
|
|
XXX - add a brief description of PROTO history
|
|
|
|
|
|
## Protocol dependencies
|
|
|
|
|
|
## Example traffic
|
|
|
|
|
|
XXX - Add example decoded traffic for this protocol here (as plain text or Wireshark screenshot).
|
|
|
|
|
|
## Wireshark
|
|
|
|
|
|
The GTP dissector is fully functional.
|
|
|
|
|
|
## Preference Settings
|
|
|
|
|
|
(XXX add links to preference settings affecting how PROTO is dissected).
|
|
|
|
|
|
## Example capture file
|
|
|
|
|
|
XXX - Add a simple example capture file to the [SampleCaptures](/SampleCaptures) page and link from here (see below). Keep this file short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically.

## Display Filter
|
|
|
|
|
|
A complete list of PROTO display filter fields can be found in the [display filter reference](http://www.wireshark.org/docs/dfref/protofirstletter/proto.html)
|
|
|
|
|
|
Show only the GTP based traffic:
|
|
|
|
|
|
```
|
|
|
GTP
|
|
|
```
|
|
|
|
|
|
## Capture Filter
|
|
|
|
|
|
You cannot directly filter GTP protocols while capturing.
