The DHCP Leases page includes a list of the leased host addresses that are part of the Quadro’s LAN. For these hosts, Quadro acts as a server
supplying them with a unique IP address. It displays a read-only table describing all the leased IP hosts and their parameters. The table contains the
following columns:
IP address - host IP address, assigned by Quadro.
MAC address - host MAC address, provided
by the host
itself.
Lease Start - date and time when the leased IP address has
been activated.
Lease End - date and time when the leased IP address has
been or will be deactivated.
Binding State – indicates the state of the DHCP lease.

Hostname - hostname, provided by the host itself.
DHCP Advanced Settings
The DHCP Advanced Settings page is used to modify the
advanced options of the DHCP server on the Quadro. This
page contains a table where a list of default DHCP server
options is already defined. More options can be added from
this page, as well as settings of the existing options can be
modified. All options in the table on this page are then sent to
the DHCP clients.
• The Authoritative checkbox is used to enable/disable
authoritative mode on the Quadro DHCP server.
Disabling the checkbox is recommended if several
DHCP servers are used on the network and the Quadro
should provide network parameters to IP phones only.
• The Ping Check
checkbox enables checking the
availability of an IP address on the network before
providing it to a client. If this checkbox is selected, the
Quadro will first ping an IP address retrieved from the IP
pool and wait for a reply. If no a reply is received within a
timeout specified in the Ping timeout text field (by
default 1 sec), the retrieved IP address will be provided
to the client. If otherwise, a new IP address will be
retrieved from the IP pool and the procedure will be
repeated. If this checkbox is not selected, the Quadro
will provide an IP address immediately when requested.

The Option Value Type drop down list is used to select the type of the option value. It may be an IP address, a boolean or integer value, etc.
The Option Value text field is used to insert the value of an option. Depending on the selected Option Value Type, this field should have the
corresponding value. Warning messages will prevent saving if the value inserted in this field does not correspond to the requirements of the
Option Value Type. If an array should be inserted here, the values should be separated with a comma.
