| Bindings from all pools not associated with VRF:

| Manual
| 192.168.100.16      0100.0874.e675.67       Infinite

Why are you including .11 in the excluded range?  It should be assigned by
DHCP, but through a manual binding rather than a dynamic binding.  Since
.11 is excluded, it won't be assigned to the station requesting it.
