Some of the supported | ethernet cards are 10/100 (fxp0 - Intel EtherExpress Pro/100, de0 - DEC | DC21140, vx0 - 3Com 3c590). Shouldn't they autonegotiate to 100BaseT | when connected to a 100BaseT network? I have tried to connect two | FreeBSD 2.1.5 machines with Intel and DEC chip based cards with an | ethernet X-wire - the 100 LED goes on but packets cannot be transmitted | without errors. (seems like some PHY config problem in the driver...) 100BaseTX with a hub seems to work just fine. I've had trouble getting it to work with just a crossover cable lately though... | Is it correct that fast ethernet hosts should only use the "standard" | IEEE 802.2 encapsulation (RFC 1042) and not the classical Ethernet | ecapsulation (RFC 894)? No. And in fact the classical Ethernet encapsulation (type code in bytes 13-14) is now an official part of 802.3. | Is this beeing observed by other OS? No. All the ones I've seen use the classical Ethernet encapsulation for IP. | As far as I | can see, the Ethernet sublayer in FreeBSD only supports the RFC 894 | style encapsulation for IP. If this is a problem are there any fixes? It's not a problem. Steinar Haug, Nethelp consulting, sthaug@nethelp.no
