Description Carlos Cherem 2000-12-08 02:11:07 UTC
When i try to use the 3com 3c905c card in my Linux 6.1 (Kernel 2.2.12-20) 
and conect these machine on a Cisco Catalist Switch, the network was work 
for a few minutes and down. If these machine is conect on a hub, the 
network will be work very well. The problem is relationed with the Switch.

My Switch is working very well with my network and all computers.

I was get the driver from the 3com site, and i choose the apropriate 
version for my Linux and i compile as recomendade.

I was try many times and none ... and i put my old card realtech-8029 to 
work again.

Please, if anyone have the solution for this problem, report here !

Thank you Very much !

Most probably your catalyst switch has been statically configured to 100? full-duplex,
and your network card is in autonegotiate state.  In that case, the switch has to be reconfigured
or the card forced to a different mode (in /etc/conf.modules).

Some Cisco switches have been reported to be unreliable with autonegotiation.
