Unable to drop down layer3 interfaces for dhcp configuration in Panorama template

• Can not assign an interface to DHCP server or Relay from Panorama UI under Template.
• When trying to configure DHCP using GUI: Template > Network> DHCP > Interface, drop-down displays spinning icon and never shows available interfaces.

• Any Panorama
• PAN-OS 9.0.3, 9.1.0, 10.0.0
• DHCP configuration via Template.

1. Upgrade to one of the releases with the fixes: any SW post 9.1.0, 10.0.0. This issue is also going to be fixed in 9.0.13 (pending release as of 2/11/21 )
2. If an upgrade is not possible, Configure DHCP from Panorama CLI:
   • For DHCP server

> configure
# set template <template name> config network dhcp interface <interface name> server ip-pool <Value> option subnet-mask <Value>
# commit
# exit

• For DHCP relay

> configure
# set template <template name> config network dhcp interface <interface name> relay ip enabled yes server <IP Value>
# commit
# exit
