We have legacy and UEFI clients.
We are able to PXE boot either legacy BIOS or UEFI BIOS based clients but unable to PXE boot both at the same time .
Currently SCCM is working with DHCP bootp options(066+067).
Our DHCP server and SCCM server are in same VLAN but clients are in different VlANS.
For this purpose we have configured an IP helper on Cisco-3750 switch, pointing towards centeral DHCP server.
On DHCP server we have configured bootp options ponting towards SCCM server.
On Cisco Switch we have created a second IP helper with SCCM server IP and deleted Bootp options on DHCP server but we get PXE-E53 error.
Is it possible to configure PXE boot without DHCP bootp options ?.
Is it any other way to IP helper for SCCM on cisco switches ?
I have used this method
interface Vlan XX
no ip address
ip helper-address DHCP server
ip helper-address SCCM server
Any help or suggestions are welcome
