Address from wrong pool

Dear list users
I have the following config file:
failover peer "DHCP-IEU" {
primary;
address 130.60.17.131;
port 520;
peer address 130.60.33.131;
peer port 520;
max-response-delay 60;
max-unacked-updates 10;
mclt 1800;
split 128;
load balance max seconds 5;
}
ddns-update-style none;
option domain-name-servers 130.60.128.3, 130.60.64.51;
option domain-name "uzh.ch";
authoritative;
log-facility local2;
host IEU_0024_L1 { hardware ethernet 00:00:aa:9d:26:79; }
host IEU_0025_L1 { hardware ethernet 00:10:83:41:ef:e4; }
class "IEU_0024_L1" { match hardware; }
class "IEU_0025_L1" { match hardware; }
subclass "IEU_0024_L1" 1:00:00:aa:9d:26:79;
subclass "IEU_0025_L1" 1:00:10:83:41:ef:e4;
subnet 130.60.33.32 netmask 255.255.255.224 {
option routers 130.60.33.33;
option broadcast-address 130.60.33.63;
pool { allow members of "IEU_0024_L1" ; range 130.60.33.36; }
pool { allow members of "IEU_0025_L1" ; range 130.60.33.37; }
pool {
failover peer "DHCP-IEU";
deny dynamic bootp clients;
allow known-clients;
range 130.60.33.40 130.60.33.50;
}
default-lease-time 21600;
max-lease-time 21600;
}
I'd expect that the hosts "IEU_0024_L1" and "IEU_0025_L1" would get
the adresses from "their" single-IP pools, that is, 130.60.33.36 and
130.60.33.37. Instead, they get an address from the "known-clients"
pool (130.60.33.40 - 130.60.33.50). I understand that those two hosts
would be allowed to pull an address from both pools, their single-IP-
pool (as they are members of the subclass allowed there), but also
from the known-clients pool, since they are of course known-clients.
How does dhcpd decide in such a case from which pool to assign an IP?
Order in which they appear in the config (obvioulsy not, or it should
work with that config...)?
Why such a configt? I'd like to assign some hosts a fixed IP, but I'd
like it to be logged whenever they get a lease, so that's why I don't
use the fixed-address statement. Other (in fact, most) hosts are to be
assigned their IP dynamically (from the known-clients pool).
Thanks for any insights,
Tina
