state enumint(available=1, offered=2, leased=3, expired=4, unavailable=5, released=6, other-
available=7, pending-available=8)
Displays the current state of the lease.
1 available
The lease is not currently leased by any client. Any
client information is from the most recent client to
lease or be offered this lease.
2 offered
The lease is offered to the associated client. In many
cases, the database is not written with information
concerning offering a lease to a client since there is
no requirement to update stable storage with this
information.
3 leased
The lease is currently leased to the client whose
information appears in the lease.
4 expired
The client specified has not renewed the lease, and it
expired. Upon expiration the DNS information for this
client was scheduled for removal.
5 unavailable
The lease is unavailable. It was made unavailable because
of some conflict. A ping attempt might have shown that the
another client using the, or the DHCP server might have
detected another DHCP server handing out this IP address,
or a DHCP client might have declined the lease. Use
start-time-of-state to determine when the lease became
unavailable, and look in the log file around that time to
determine exactly why the lease became unavailable.
6 released
The client specified has released the lease, but the
server was configured to apply a 'release-grace-period'.
The lease won't be made available until the
grace-period expires.
7 other-available
Used only when failover is enabled. A lease in the
other-available state is available for allocation by the
other server in the failover pair, but not available for
allocation by this server.
8 pending-available
Used only when failover is enabled. A lease in the
pending-available state will be available as soon as
this server can synchronize its available state with
the other server.
