Hi there,
What exactly do you mean with packet configuration? Do you mean wich types of packets (V2, Novell Raw, IEEE 802.3 (SNAP)) you see on your network?
This depents most of the time on the application you are running. MS is using a lot of version 2 packets, but applications using a DSAP/SSAP are using IEEE 802.3 or even a IEEE 802.3 SNAP frame type if the app has a SNAP number (2 bytes Vendor and 2 bytes type field in the SNAP header).
So, if you force for example your NIC to use only V2 packets, then an application using a DSSAP/SSAP or SNAP number will have big problems then because this app cannot work with V2 packets.
Hope this helps you on the way.
Regards,
Robert
