PXE Boot with ip-dhcp-relay and without DHCP Options

Switching
1

Does anyone has PXE Boot with WDS running just with ip-dhcp-relay in different VLANs?

Our Settings ist an OS6900-X24C2 with the 2 VLANs IP Interfaces

ip dhcp relay admin-state enable
ip dhcp relay per-interface-mode
ip dhcp relay pxe-support
ip dhcp relay interface "TEST" destination 1.2.3.4 (DHCP Server)
ip dhcp relay interface "TEST" destination 1.2.3.5 (WDS Server)

Without Option 66 and 67 i can not boot via PXE our Lenovo Laptops to the WDS

Do i miss something?

Thanks

Hi I have tested and is working fine with below setup.

6900X72 ----------6860N(L2 switch) ------ PC (Both PXE Client & PXE Server connected in Same VLAN). On 6900 You do not need any command of PXE.

If you enable DHCP-SNOOPING on 6860N and PXE-Server is connected to 6860N also please trust the port.

With DHCP-snooping enabled on 6860N, I see bootp request from Client is dropped by 6860N . This was confirmed as bug and fix will be available in 8.10.R03 which is expected in June.

Note : DHCP Server is behind 6900-X72 and different VLAN than PXE-CLIENT & PXE-SERVER

To Conclude , it should work without DHCP-snooping without any issues and It is working for me with WDS.

I hope it helps
