From the Wiki:
Lease status:
waiting - un-used static lease
testing - testing whether this address is used or not (only for dynamic leases) by pinging it with timeout of 0.5s
authorizing - waiting for response from radius server
busy - this address is assigned statically to a client or already exists in the network, so it can not be leased
offered - server has offered this lease to a client, but did not receive confirmation from the client
bound - server has received client’s confirmation that it accepts offered address, it is using it now and will free the address no later than the lease time
As I read this, if you are seeing IPs with a status of “Busy”, it sounds like either a bunch of devices are set to Static IPs in your DHCP range, or there is another DHCP server on your network. Not particularly good. I don’t think I have ever seen anything except Waiting and Bound on my network.
i’m sorry, i might have mislooked it. no status busy now, everything is bound. my problem is clients keep having the same IP all over again. is it possible to have them take the lowest possible IP?
