Hi! I'm trying to deploy PE servers (Rx30s and C6320s) via PXE in UEFI boot mode, without success.
The servers PXE-boot just fine when configured in BIOS boot mode, but switching to UEFI apparently makes the initial DHCP request timeout, and generate a PXE-E18 Server Response Timeout error. Looking at the network traffic, I see just 2 DHCP frames in the initial exchange: 1. DHCP Discovery from the server 2. DHCP Offer from the DHCP/TFTP server And then nothing else, as if the PXE-booting server never received the DHCP Offer, or at least didn't act on it. Again, the exact same setup works flawlessly when the PXE-booting node is in BIOS boot mode. Both the Ethernet switches and DHCP servers are configured to use Jumbo Frames (MTU 9000). I know that other vendors have released fixes in their UEFI network stack in the past to fix issues related to that, but I don't have any evidence that jumbo frames are involved here. Anyway, has anybody ever observed the same behavior? Thanks! -- Kilian _______________________________________________ Linux-PowerEdge mailing list [email protected] https://lists.us.dell.com/mailman/listinfo/linux-poweredge
