<<< DECWET::DOCD$:[NOTES$LIBRARY]WINDOWS-NT.NOTE;1 >>> -< Windows NT >- ============================================================================= ==, Note: 4067.0 FDDI, ethernet II packet problems? 0 replies NQOS01::nqsrv401.nqo.dec.com::Cindy Richardson " 22 lines 12-FEB-1996 06:48 ----------------------------------------------------------------------------- --- (Cross- posted in NT Conference) I have a customer using an AlphaServer 2100 running windows NT. THey have an FDDI PCI controller in it (ours). They are having trouble configuring the card to send Ethernet II packets. They go into the configuration of the card for IPX/SPX traffic and choose frame type of Ethernet II. When they do this, the Novell Server (on the Ethernet side - across a CISCO CDDI/FDDI bridge) complains about 802.3 packets being sent. A scope on the Ethernet segment actually shows a bunch of 802.3 packets being sent across. The customers basic complaint is that the FDDI Card is not sending Ethernet II packets. My question to them was - what did the frames look like on the FDDI side - they are looking at packets so far down the line who knows what is coming out of the FDDI card. My question here is has anyone seen any problem in doing this? Does something possibly need to be defined at the CISCO device or is it purely a passive device - Enet II in, Enet II out? They are using the driver that ships with the Windows NT Server 3.51 software - which is the latest version they can find. Thanks for any pointers.... Cindy

1954.1 | Use FDDI_SNAP not ETHERNET_II for FDDI | NETCAD::STEFANI | I *CAN* drive 65! | Mon Feb 12 1996 13:15 | 9 |
ETHERNET_II is the Novell frame type for DIX (Ethernet V2) frames on Ethernet. The corresponding Novell frame type on FDDI is called FDDI_SNAP. If you're running FDDI on Windows NT, try to configure IPX for "auto" or "SNAP" or "802.2 SNAP". I'm sure this is a simple configuration problem. I've heard of no reports of IPX problems on FDDI under Windows NT. - Larry |
