Hi all, I have a question about the standard behaviour of gPXE 1.0.1 and iPXE. (The tests I did were using VMware E1000 based boot-rom)
the PXE 2.1 spec states [in para. 2.4.4] that the client should provide option 71 (PXE_BOOT_ITEM) in boot server discovery but I cannot see this in a trace using the gPXE 1.0.1 boot rom. I have a trace when using a CA MPC boot server (all I have access to currently). The extended DHCP offer from the boot server has option/sub-option 43/8 and 43/9 (PXE_BOOT_SERVERS and PXE_BOOT_MENU respectively) and these both have the boot-server type (0007) present. The client then sends a DHCPREQUEST boot server discovery request without the PXE_BOOT_ITEM type and the CA server ignores this request as the explicit boot server type has not been specified. Table 2.1 states that the PXE_BOOT_ITEM (71) type is required (not optional) and has note #6: This option is required to discover Boot Servers. Only the client may change the type field; either the client or the server may change the layer field. Layer 0 always indicates the first boot file for a particular Boot Server type. Boot Servers capable of providing the boot file requested in the PXE_BOOT_ITEM must respond. Boot Servers not capable of providing the boot file requested must not respond. As far as I can tell then, the CA boot-server is behaving correctly. Am I understanding this correctly or not? Thanks for any advice, regards, Carl _______________________________________________ gPXE mailing list gPXE@etherboot.org http://etherboot.org/mailman/listinfo/gpxe
