Hi,

Sorry my bad English (I'm from Russia).

I'm studying network protocols, and I created a sniffer. Now I study formats Ethernet frames, the frame 802.3/LLC has two byte field DSAP and SSAP determine SAP (Servicse Access Point) source and destination.

I can not find a list of all the values of these fields (found only 6 values). Looked here:[^] but there's so much to appartnoy (SP?) of what to look for it can take weeks.

Please give me a link or list of values.

Thank you.

I found list of SAP values in source code of project "Wireshark" (file "llcsaps.h"). I do not know where the creators of "Wireshark" have taken this list. But I think they can trust.
