OK. It sounds as though you're having problems with FIP. Useful things to try would be to build with DEBUG=fcoe and (if possible) to try capturing the traffic. Capturing traffic might be difficult given that FCoE tends to use VLANs. iPXE will use FIP VLAN discovery to detect an FCoE VLAN. You can see if any VLAN devices have been created via "ifstat". Once a VLAN has been discovered (or VLAN discovery has timed out), iPXE will use FIP to detect an FCF. The FC device (visible via "fcstat") will be created only once a FCF has been detected (or FCF detection has timed out). Common problems with iPXE FCoE are: a) NIC drivers that don't strip the Ethernet CRC from the received packet: this doesn't affect TCP or UDP but will break FCoE b) NIC drivers that don't enable promiscuous mode Michael _______________________________________________ ipxe-devel mailing list [email protected] https://lists.ipxe.org/mailman/listinfo.cgi/ipxe-devel
