the DHCP server is Cisco IOS. Usually when i set the only 60 & 43 (ascii value as IP Address ) i get PXE is
“Bad or missing PXE menu and/or prompt information”
As i am doing imaging for Laptops (UEFI targets) i tried setting up 66 and 67 along with 60 & 43 but it does not work the target does not get DHCP ip itself “No DHCP or DHCP proxy”.
When i remove 43 option and keep 60 ,66 and 67 i get error “TFTP Open Timeout”.
Below is the way network team set the option
option 60 ascii "PXEClient"
option 43 ascii "IP-Address of OSD"
option 66 ascii "IP-Address of OSD"
option 67 ascii “Rembo-x64UEFI”
i followed document for this setting but document does not specify anything for CISCO IOS . Its Cisco 3800 series switch
Adding to my above point the DHCP and OSD Server are in Different VLAN’s
