26 Chapter 2 Command Descriptions
DHCP server will mark the address as unavailable. The lease will remain
in this state for 4 hours, after which it is reverts to the Reserved (inactive)
status.
Offered (pre-lease)
A lease has been offered to the given client, but that client has not yet
requested that the lease be acknowledged. It may be that the client also
received an offer from another DHCP server, in which case this offer will
expire in approximately 2 minutes. If the client requests this lease before
that 2 minute interval elapses, this lease will change status to Assigned.
Released
A lease was previously assigned to the given client, but that client has
proactively released it. A lease in this state will remain for 1 hour, after
which it is deleted. If the same client requests an IP address before the
lease is deleted, it will be given the same IP address previously served to
it.
Unavailable Address
A lease was offered to a client, but that client actively declined to use the
IP address. Typically this is because the client determined that another
host on the same subnetwork is already using that IP address. Upon
receiving the client's decline message, the DHCP server will mark the
address as unavailable. The lease will remain in this state for 4 hours,
after which it is deleted.
This status may also occur if the DHCP Server determines that the IP
address is in use before it offers the address to a client. See the
"set dhcpserver" command option "conflictdetect" option.
