[Kea-users] flex-id host reservations via host_cmds hook in 1.3 beta?

Jason Lixfeld
Hi all,

Does anyone know if using Kea 1.3 (beta) and the host_cmds hook (for 1.2 currently), whether one will be able to insert a host reservation using the flex-id identifier type over the API via the host_cmds hook instead of inserting the host reservation into the database directly?  This is, of course, assuming that one would be using the flex-id hook as well.

http://kea.isc.org/wiki/Commands Section 2.3 makes the following statement:

"The details are TBD, but it seems very likely that the initial implementation will allow specifying the following identifier types: hwaddr (hardware/MAC address), client-id (client-identifier option in DHCPv4), DUID (client-id option in DHCPv6), remote-id (remote-id sub-option in option 82), circuit-id (circuit-id sub-option in option 82). Additional identifier types are likely to be defined in the future.”

Not sure if I should interpret that verbatim and not specifically mentioning flex-id implies that it is not supported, or even on the radar, or if it is and just isn’t mentioned.

Also, while trying to verify it for myself, I ran into an issue trying to do a simple reservation-add using an example from the administration guide:

BlackBox-3:~ jlixfeld$ curl -X POST -H "Content-Type: application/json" -d '{ "command": "reservation-add", "arguments": { "reservation": { "subnet-id": 1, "hw-address": "1a:1b:1c:1d:1e:1f", "ip-address": "192.0.2.202" } } }' http://10.219.66.10:8080/
[ { "result": 2, "text": "'reservation-add' command not supported." } ]

Any thoughts or insights on either?

Thanks!
