Hi,

Normally/commonly the Diagnostic Responder (DIAG) protocol is useful in analyzing NetWare LANs.

DIAG can be used for connectivity testing, configuration and information gathering.

The DIAG request packet structure is as under

Exclusion address count (1 byte)

Exclusion address 0 (6 bytes)

Exclusion address 79 (6 bytes)

If Exclusion address count =0 it means all the stations should respond.

The DIAG response packet structure is as under

Major/minor version

SPX diagnostic socket

Component count

Component type

In sap terms DIAG is

Dynamic Information and Action Gateway: Protocol for communication

between SAP GUI and the application server (also known as the SAP GUI protocol).

This is also used when there is flow of data between the presentation layer and application layer

so that the flow don not consists of any prepared screens rather it conains onlylogical data,

compact inf about control elements and user input and the

amount data transferred is kept to minimum

Use of this in SAP is documented at the following links:

More resources is available on the net pl check.

Hope this can be a start for your quest.

If useful encourage by awarding points.

Hello Oliver,

what kind of description you are looking for?

I have serious doubts that definition/documentation of the DIAG-protocol has been published outside of SAP.

Hey Rolf-Martin,

I´m looking for a description what DIAG is used for, on which protocols it is based (protocol stack) and what features it has ( error correction etc).

I already know some details, but I need a real publication to refer to.

Thx a lot

Hello Oliver,

I have double checked today again with the group responsible for the DIAG protocol.

Unfortunately there is no information available which provides some helpful information without disclosing details.

Sorry for not having better news.
