24.7 Production Series / Re: KEA not respecting reservation
« on: July 12, 2024, 01:28:56 pm »
The KEA error log explains the address you chose for hifiberryamp is not available, as it's already in use, so instead it's advertised (offered) 192.168.30.101.
Static lease changes from ISC DHCP to KEA:
DHCP reservations must fall within the Interface subnet and must be outside any DHCP scope defined in KEA DHCP server.
This is a more strict configuration requirement than the legacy ISC DHCP Server.
Having static leases defined that fall within a scope does not prevent a DHCP server from offering that IP as a lease, which may (mistakenly) be the expected behaviour.
In your question you don't specify what your DHCP scope(s) [also known as pool(s)] is/are, so I'll assume you've left these as default which matches the interface's subnet.
This is an example of a CORRECT config:
And below is an example of a INCORRECT config:
If this doesn't work, can you confirm the scope(s) set for KEA on this interface
