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.
DHCP Settings for the VLAN Interface
DHCP Settings for the VLAN Interface is used to establish virtual networks in the Quadro’s LAN or to integrate the Quadro into the corporate
network’s virtual LAN/WAN. DHCP service can be activated both on virtual LAN or WAN interfaces. VLAN is useful in corporate companies to divide
large networks into groups and to have devices like Quadros and IP phones in each network separated (for example, to separate networks for data
and voice transmission). Priorities may be assigned to the interfaces for packets prioritization.
With VLAN configuration, each virtual network will be characterized with a VLAN ID (tag). Packets addressed to that network will be checked towards
the ID and if the ID number defined in the incoming packets matched the corresponding network’s ID, the packets will be accepted. Otherwise, if the
ID does not match, the packets will be dropped. In the same way, if the Quadro is integrated into the network that uses VLAN technology, outgoing
packets should have the ID number of the corresponding virtual network, for the remote party to accept the packets from the Quadro.
The DHCP Settings for the VLAN Interface page
contains a table with all enabled VLAN interfaces created
in VLAN Settings page (see below) and the corresponding
parameters (VLAN ID, IP Address Range and WINS
Server). This page contains the following components:
Enable DHCP Server checkbox activates the DHCP
server on Quadro for VLAN. With this checkbox enabled,
Quadro will be able to assign dynamic IP addresses to the
devices in its VLAN.
Activate functional button is used to activate DHCP
service on one of the VLAN interfaces in the list. Only one
VLAN interface can have DHCP service activated.
Edit functional button opens a page where the
corresponding VLAN interface can be configured and
controlled. This page contains all the same components as
the
DHCP Server Settings page does.
Fig. II-228: DHCP Settings page for VLAN interface
VLAN Settings link moves to the page where virtual
LAN/WAN interfaces may be created.
VLAN Settings
page lists all existing virtual interfaced
created on the Quadro and allows you to create new
interfaces.
Enable and Disable functional buttons are used to
correspondingly enable and disable the selected virtual
interface(s).
Fig. II-229: VLAN Settings
Add functional button opens an Add Entry page where a
new virtual network can be defined. The page consists of
the following components:
Enable checkbox is used to select whether the
corresponding virtual interface will be enabled or disabled
after it is created.
Interface Type manipulation radio buttons selection
allows to choose whether the virtual interface will be LAN
or WAN.
VLAN ID text field requires the virtual network ID. Numeric
value in a range from 0 to 4094 is allowed in this field.
Priority drop down list is used to select the priority of
packets in the corresponding interface. Packets with the
lower priority (0) will be delivered first.
IP Address text field requires the IP address of the virtual
interface.
Subnet Mask text field requires the subnet of the virtual
interface.
