The list -subnet command lists all leases in a subnet
(scopes whose address and mask match the query).
The list -lansegment command lists all leases in a LAN
segment, meaning all leases in scopes whose address and mask
match the query, as well as leases in secondary scopes whose
primary scope's address and mask match the query.
The list -macaddr command lists all leases that are associated
with the specified MAC address.
Note: The list -macaddr command for Network Registrar 6.3
and earlier clusters can be extremely slow. In release 7.0
and later, performance is improved. The recommended syntax
is -macaddr=<mac-address>.
lease [<vpn-name>/]<ip-address> activate
lease [<vpn-name>/]<ip-address> deactivate
The activate and deactivate commands tell the DHCP server
to make the specified lease active or inactive. An inactive
lease is not given out, even if it is in the available state.
Making a currently leased lease inactive does not affect its
behavior until it has expired and become available again.
lease [<vpn-name>/]<ip-address> force-available
The force-available command forces the specified lease into the
available state.
lease [<vpn-name>/]<ip-address> macaddr
The macaddr command provides the MAC address associated with
the specified lease.
lease [<vpn-name>/]<ip-address> get-scope-name
The get-scope-name command provides the scope to which the
lease belongs.
lease [<vpn-name>/]<ip-address> send-reservation
The now-deprecated send-reservation command sends an existing
reservation immediately to the DHCP server without requiring a
server reload. You must first run the scope <scope-name>
addReservation command for this reservation.
The recommended sequence is:
nrcmd> scope <scope-name> addReservation <ip-address> <mac-address>
nrcmd> save
nrcmd> lease <ip-address> send-reservation
This sequence ensures that the configuration database contains
the lease and reservation as well as the running server, since
the send-reservation command directly affects only the running
server's in-memory database, and does not itself persist past
the next server reload.
lease [<vpn-name>/]<ip-address> delete-reservation
The now-deprecated delete-reservation command deletes an
existing reservation immediately from the DHCP server without
requiring a server reload. It is important to ensure that
the configuration which the DHCP server uses for the next server
