Client not sending DHCPREQUEST after offer.

[ritul guru (riguru)]

How can I check if IP source guard is enabled for a port on switch?

I am not sure, but I am able to do legacy boot on same client port (switch N5k).
So this should not be a concern.

Is the client on a port using IP Source Guard by any chance?

Thanks,

Hi,
I am facing similar problem while trying to boot to uefi rhel6.5 OS through uefi pxe boot.

Pxe client sends DHCPDISCOVER and server is reverting with DHCPOFFER, but this keeps on happening, client is not sending DHCPREQUEST further.

I tried dumping pxe server on eth2, it looks like pxe client DHCPREQUEST is not reaching the server. What could be the problem?
