My sample configuration is below:
"reservations": [
{
"flex-id": "'0x4857544394969D21d4:cf:f9:ff:dd:bb'",
"ip-address": "10.215.160.101"
}
],
"hooks-libraries": [
{
"library": "/usr/local/lib/hooks/libdhcp_flex_id.so",
"parameters": {
"identifier-expression": "concat(relay4[1].hex,
hexstring(pkt4.mac, ':'))"
}
}
],
Kea log is below:
INFO [kea-dhcp4.flex-id-hooks/21510] FLEX_ID_EXPRESSION_EVALUATED Expression
evaluated for packet to "4857544394969D21d4:cf:f9:ff:dd:bb" (size: 33)
INFO [kea-dhcp4.leases/21510] DHCP4_LEASE_ALLOC [hwtype=1 d4:cf:f9:ff:dd:bb],
cid=[01:d4:cf:f9:ff:dd:bb], tid=0x5545542e: lease 10.215.160.50 has been
allocated
If reservation works correctly, the host should have address 10.215.160.101.
But it's not reserved, but getting lease from pool.
what am I missing here, pls correct me.
BR,

Subject: using flex_id for combined reservation identifiers
Hello,
I'm trying to identify and reserve a host by combination of "mac address AND
circuit id" with no luck.
How should I express it? Any reply would be appreciated, Thank you
MAC address: e8:37:7a:00:00:00
Circuit ID: 4857544394969D21
...

} ],
...
"hooks-libraries": [
{
"library": "/usr/local/lib/hooks/libdhcp_flex_id.so",
