To support BIOS & UEFI Firmware based hardware, we need to execute following commands on Cisco Switch (Global Configuration Mode):
IP helper-address <IP address of DHCP server>
IP helper-address <IP address of WDS server>
IP forward-protocol UDP 4011
CONFIGURATION of IP Helper Tables explained
When the PXE client PC, the DHCP server, and WDS Server, are located on different subnets or vlans, IP helper tables need to be set up in the routers/switches so that the PXE network requests can be routed correctly to the appropriate server. Once the PXE network requests are routed correctly. the appropriate servers can answer. Requirement here is:
- Client to get IP address from DHCP Server
- Directing a client to appropriate Network Boot Program (wdsnbp.com or wdsmgfw.efi)
