The port will show Link and auto negotiate, and 'show fdb' will list a mac address, but hosts attached to the port aren't able to receive an address via dhcp. So far the only solution has been to reboot the affected slot. About 6 months ago we experienced similar problems on unstacked X440-48's. Extreme blamed a Broadcom driver for the problem which was reported resolved.<BR /> <BR /> Any feedback on X440's in general would be appreciated.<BR /> <BR /> Thanks!
