I have the same issue with the 905B and 905C, also used the 3Com Dos Based CFG util to hard code the Nics to 100/full. -----Original Message----- From: [email protected] [mailto:[email protected]]On Behalf Of Emmanuel Viennet Sent: Thursday, January 09, 2003 2:55 AM To: [email protected] Subject: [vortex] 3c905C-TX : not working in 100Mbps / Full Duplex ? Hi, we use 3COM 3c905C-TX PCI adapters under linux 2.4.18 (RedHat 8.0 or 7.3), using 3c59x driver module. It works fine in 10 Mbps half-duplex, but we could'nt set it to 100/Full Duplex. The adapter is connected directly to a CISCO 2900 10/100 switch. We can't get setup a correct connexion at 100/FD. We tried the following: - switch auto-negociating, card auto-negociating - switch forced to 100/FD, card forced (either with options 3c59x options=0x0200 or options 3c59x options=4 full_duplex=1 or even using mii-tool -F 100baseTx-FD ) In all cases, we get "carrier errors", as in this example: eth1 Lien encap:Ethernet HWaddr 00:04:75:C8:6B:B6 inet adr:10.10.0.1 Bcast:10.10.255.255 Masque:255.255.0.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3421953 errors:0 dropped:0 overruns:1 frame:0 TX packets:2794227 errors:0 dropped:0 overruns:0 carrier:2793937 collisions:0 lg file transmission:100 RX bytes:980768562 (935.3 Mb) TX bytes:2223140870 (2120.1 Mb) Interruption:5 Adresse de base:0xe880 Connectivity is OK, but paquets are loosed, and NFS performance is very poor. We tried this on several PC, several 3COM cards and several switches with the same results... The same setup works perfectly with Ethernet Pro 100 (eepro100) or older 3COM cards (905B). Any advice ? (we have a *lot* of 905C-TX and feel quite desesperated...)
