    OK guys...

    I have a Cisco Switch and I have it in a Residence Hall at a college. A student with a Dell laptop plugs in and the switch thinks that his ethernet card is sending out bad packets and shuts his port down automatically all the time. Has anyone heard of this happening?? What is the deal?

    I have ran into the same issue with our Cisco switches. They seem to be sensitive in this area.

    The workaround I use is to set both the port and the NIC at specific speed and duplex. I never really have trusted "auto-negotiation".

    Also check to see that a current NIC driver is installed from the Dell support site.

    You can also look at the www.cisco.com site. Their tech support there is good.

    The residence halls are all 10MBps so should I set the switch to 10MBps for just that port or for the whole switch?? And what duplex should I try using? Do I have to disable auto-negotiation for the whole switch or just that port?

    Thanks!

    I set mine port by port. For your situation i'd go with 10/full to start and do it port by port as needed. If that doesn't work slow it down to 10/half. I've had to use the latter setting on old HP Jetdirect cards.

    Good Luck!
