Hello,
Now i'm trying to configure mysql host reservation. But no luck. Where could be
my mistake?
Here is my configurations:
"host-reservation-identifiers": [ "circuit-id", "hw-address", "flex-id" ],
"reservation-mode": "global",
"hosts-database": {
"type": "mysql",
"name": "kea",
"host": "",
"user": "myuser",
"password": "mypass"
},
"hooks-libraries": [
{
"library": "/usr/local/lib/hooks/libdhcp_flex_id.so",
"parameters": {
"identifier-expression": "concat(relay4[1].hex,
hexstring(pkt4.mac, ''))"
}
}
],
MySQL insert statement:
START TRANSACTION;
SET @ipv4_reservation='10.10.10.10;
SET @identifier_type='flex-id';
SET @identifier_value='4857544315C6342Fd4cff9ffddbb';
SET @dhcp4_subnet_id=1;
SET @next_server='10.10.10.1';
SET @server_hostname='kea.test.com';
SET @boot_file_name='bootfile.efi';
INSERT INTO hosts (dhcp_identifier,
dhcp_identifier_type,
dhcp4_subnet_id,
ipv4_address,
dhcp4_next_server,
dhcp4_server_hostname,
dhcp4_boot_file_name)
VALUES (UNHEX(REPLACE(@identifier_value, ':', '')),
(SELECT type FROM host_identifier_type WHERE name=@identifier_type),
@dhcp4_subnet_id,
INET_ATON(@ipv4_reservation),
INET_ATON(@next_server),
@server_hostname,
@boot_file_name);
COMMIT;
Kea Log:
INFO [kea-dhcp4.flex-id-hooks/17331] FLEX_ID_EXPRESSION_EVALUATED Expression

Subject: Re: [Kea-users] using flex_id for combined reservation identifiers
If your hook evaluated your expression as "4857544394969D21d4:cf:f9:ff:dd:bb"
then try to add reservation something like this
"reservations": [
{
"flex-id": "4857544394969D21d4:cf:f9:ff:dd:bb",
"ip-address": "10.215.160.101"
}
Also check if your flex-id identifier is enabled for quering:
"host-reservation-identifiers": ["duid", "*flex-id*"],
