DHCP Settings for the LAN Interface
The
DHCP Settings for the LAN Interface
page provides the option of enabling a DHCP server and controlling the Quadro user’s LAN settings.
Therefore, Quadro LAN users will automatically be provided with the following settings using the configured parameters:
•
IP addresses
•
NTP (corresponds to the Quadro’s IP address)
•
WINS server
•
Nameserver (corresponds to the Quadro’s IP address)
•
Domain name
The
DHCP Settings for the LAN Interface
page offers the
following input options:
Enable DHCP Server
checkbox activates the DHCP server
on Quadro. With this checkbox enabled, Quadro will be able
to assign dynamic IP addresses to the devices in its LAN.
Give leases only to hosts listed in the static MAC
address binding table
checkbox enables the DHCP
services only for the devices listed in the table below. With
this checkbox selected, no DHCP services will be provided
to the other devices.
Please Note:
When this checkbox is selected, all IP phones
configured to use plug and play or auto configuration
services (see
IP Line Settings
) will keep their IP addresses
received from the DHCP server of the Quadro. The IP
phones that are configured manually should be added to the
Special Devices
table to keep their IP addressed.

IP Address Range
defines a range of IP addresses that will be assigned to the Quadro LAN users. The IP range must be at least 6, otherwise the
error message “Address Range too small” will prevent it from being saved. The error message “Address Range too large” will appear if the IP range
is greater than 254.
WINS Server
defines a WINS server IP address for the Quadro LAN users.
DHCP Advanced Settings
link leads to the page where the advanced options of the Quadro's DHCP server can be configured.
The
Special Devices
table on this page allows you to set a static IP address binding on the MAC address of the device in the Quadro’s LAN. When
this table is configured, the devices with defined hostnames and MAC addresses will always get the same LAN IP address from the DHCP server.
Otherwise, devices not listed in this table will get dynamic LAN IP addresses. This table is also displayed in the
System Configuration Wizard
.
Add
functional button opens an
Add Host
page where a
new static MAC address binding can be defined. The page
consists of the following components:
Hostname
text field requires the hostname of the device in
the Quadro’s LAN.
MAC Address
text fields require the MAC address of the
device in the Quadro’s LAN.
Static IP Address
text fields require a fixed IP address of
the device in the Quadro’s LAN.
Please Note:
If you leave this field empty, the device in the
Quadro’s LAN will get the first available IP address from
range defined in the
DHCP Settings
page (see above).

View DHCP Leases
leads to the page where the DHCP leased LAN IP addresses are listed.
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
