Dhcp Advanced Settings - Epygi Quadro4Li Administrator's Manual

Quadro4Li Manual II: Administrator's Guide
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 - 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 following functional buttons are available:
