Hi there,

Just after some advice regarding help with PXE boot.

I have the following set up

set forwarding-options dhcp-relay server-group DHCP-servers 10.64.40.104
set forwarding-options dhcp-relay server-group DHCP-servers 10.64.40.105
set forwarding-options dhcp-relay server-group DHCP-servers 10.64.40.17
set forwarding-options dhcp-relay active-server-group DHCP-servers
set forwarding-options dhcp-relay group DHCP interface vlan.10

Our WDS server is on vlan 40 (10.64.40 subnet) and we want to build machines on vlan 10

Is what i have set up correct? i did try to put in the following command but it doesn't work

set forwarding-options helpers bootp server 10.64.40.17

I get the error

[edit forwarding-options dhcp-relay]
'server-group'
'server-group' statement cannot be included along with 'forwarding-options helpers bootp' statement

"forwarding-options helpers bootp " is old DHCPD config and "forwarding-options dhcp-relay server-group" is the new JDHCPD config. You cannot have both running simulataneously . Either DHCP config or JDHCP config, for 12.1X versions JDHCP is recommended.

You dont need "set forwarding-options helpers bootp server 10.64.40.17" the remaining config looks good and expect to work.

Are you getting any issues?

show dhcp relay statistics

show dhcp relay binding

Hi Rsuraj,

Thanks for replying, i have no problem with DHCP that is working fine.

My issue is telling machines to access the PXE server, i know that you can use DHCP options to achieve this but i would rather use the "ip helper" method

Thanks

Matt

I got this working by setting the pxe server's ip in the DHCP scope options.

Still not sure why it won't work without that?
