[Kea-users] lease state, cltt, and valid-lft

[Diogo André de Assumpção]

Hi all,

I'm trying to understand these results from the lease6-get command. Particularly, why the "state" is "0" (assigned) if the cltt + valid-lft is well in the past? Any relation to the LFC process?

My logs show a couple of "ALLOC_ENGINE_V6_LEASES_RECLAMATION_SLOW" events, but all before the cltt in the example bellow.


root at dhcp-server:~# echo '{ "command": "lease6-get", "arguments": { "ip-address": "2001:db8:1234:5678::1" } }' | socat UNIX:/run/kea/kea6-ctrl-socket -,ignoreeof | jq .
{

   "fqdn-rev": false,

         }
       ]
     }
   },
   "valid-lft": 43200
 },
 "result": 0,
 "text": "IPv6 lease found."
} The timers and reclaim numbers are:
"expired-leases-processing": {
"reclaim-timer-wait-time": 3600,
"hold-reclaimed-time": 172800,
"max-reclaim-leases": 500,
"max-reclaim-time": 250,
"unwarned-reclaim-cycles": 10
},
"valid-lifetime": 43200,
"preferred-lifetime": 28800,
"renew-timer": 14400,
"rebind-timer": 23040,
"cache-threshold": .30,

Any info is appreciated.

Thanks,
Diogo
