DHCP Scope Mapping to Subinterfaces in Prisma SD-WAN (ION Device)

[SANTHAPRABU]

Hi Community,

I’ve configured two DHCP scopes with different IP subnets under the Branch Site configuration in Prisma SD-WAN. On the corresponding ION device, I’ve also created two subinterfaces, each intended for a different VLAN and subnet.

I would like to understand:
How does the ION device ensure that the correct DHCP scope is applied to the appropriate subinterface, so that clients in each VLAN/subnet receive the correct IP address range?

Do I need to explicitly map each DHCP scope to its corresponding subinterface, or does the system handle this automatically based on VLAN tagging or another mechanism?

Any clarification or best practices would be greatly appreciated.

Thanks,
