Re: [EXTERNAL] Re: [edk2-devel] NetworkPkg: Unexpected DHCP RELEASE after PXE server reply on IPv6
Hi guys,toggle quoted messageShow quoted text
Finally got some time to look into it.
Long story short, this smells like infrastructure problem.
SARR passes over 546/547 port pair. That is between UEFI PXE client and DHCP server (even if it is the same machine).
The next packet is essentially a Boot Server choice step. UEFI PXE client sends a unicast discovery packet towards Boot server (same machine, same address) coded as DHCP Request.
The release packet is a direct reaction to 3 second timeout (see time diff between packet 9 and 11).
See section 2.2.1 in PXE spec: http://www.pix.net/software/pxeboot/archive/pxespec.pdf
Please verify that your WDS service is running correctly, since clearly there is no reaction to that packet from Boot server.
