DHCP Settings for the LAN Interface

The DHCP Settings 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 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.

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.

The 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.

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:

IP Address text fields require the IP address of the device in

the Quadro’s LAN.

MAC Address text fields require the MAC address of the

device in the Quadro’s LAN.

Hostname text field requires the hostname of the device in

the Quadro’s LAN.

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

The DHCP Leased IP Addresses 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.

Hostname - hostname, provided by the host itself.
