Ip helper question for SCCM PXE

  • 1.  Ip helper question for SCCM PXE

    Posted Sep 24, 2019 03:58 AM

    I've done a lot of work recently to add in Vlans as my inherited site had everything in Vlan 1

    I've moved everything now apart from servers and a few misc devices.

    My desktops are in various vlans and they all route correctly.

    My sccm server is in vlan1 and devices not in vlan1 can't uefi pxe boot to it but they can legacy boot to it regardless of vlan. I need to set an iphelper.

    My current and only dhcp relay group (group 1) has my two DHCP servers in .52 and .54. To resolve for pxe am I adding in my sccm ip to the group (.55) (my SCCM server holds the PXE services)?

    I added it in and it does now work cross vlan. I don't get why adding the sccm server into the dhcp relay resolves it
