Zone field displays the Quadro’s host domain name as it is

configured in the System Configuration Wizard

• Time to live (TTL) text field indicates the time (in seconds)

during which the DNS server will keep the resolved names

in its cache. During this time the same address will be

resolved from the cache of the DNS server. When this

timeout expires, the requested address will be resolved

newly.

• Mail Exchange (MX) text field indicates the mail server’s

hostname. When resolving the email address, the

reference will go to the mail server defined in this field,

before being sent out to the external network. The value in

this field will be used in the MX record in the DNS server on

the Quadro.

• The table on this page lists aliases for each of the device in

the Quadro’s LAN to be resolves through the DNS server.

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.

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.

The DHCP Advanced Settings link leads to the page where the advanced options of the Quadro's DHCP server can be configured. The page is

used to modify the advanced options of the Quadro’s DHCP server. It contains a table where a list of default DHCP server options is already defined.
