How to make loop over nics when using network pxe boot?

I have Dell PowerEdge R730 and R620 series servers, each equipped with multiple add-on NICs. When booting in Legacy PXE mode, the system only attempts PXE boot from the first NIC in the boot order and ignores the remaining interfaces. Since I often don’t know in advance which NIC will have an active connection, I have to manually adjust the boot order and repeatedly reboot until I find the correct interface.

In UEFI boot mode, it’s possible to specify a maximum of four NICs for PXE boot, but even this can be inconvenient, as my servers often have 8 to 10 interfaces. On other servers I’ve used, PXE boot automatically cycles through all available NIC interfaces without manual intervention.

Does Dell provide a setting or solution to enable this automatic NIC traversal behavior during PXE boot on these server models? Any guidance or recommendations would be greatly appreciated. Thank you!

    Hi,

    UEFI is more flexible than Legacy mode, allowing booting from multiple NICs without manual reordering for each attempt (up to 4). As I know currently, the most practical and widely recommended solution is to switch to UEFI boot mode. This transition provides a notable enhancement over Legacy PXE, particularly in terms of handling multiple NICs. To my knowledge, there isn't a direct alternative that supports automatic NIC traversal.

     

    Hope that helps!
