Have you tried disabling speed and duplex negotiation and explicitly stating speed and duplex like so? ifconfig_em0="... media 1000baseTX mediaopt full-duplex" Cisco switches have a notorious history of not being "friendly" with non-Cisco hardware. Forcing duplex on both ends of the link (that means on both the host side, and the Cisco side!) usually fixes it. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
