DHCP (Dynamic Host Configuration Protocol)
DHCP is a Microsoft proprietary extension to the existing bootstrap protocol
(BOOTP). DHCP enables a LAN administrator to have a network server configure
workstations with an IP address dynamically without further intervention.
A dynamically assigned IP address is referred to as an ‘Active Lease’. The Active
Lease usually has an expiry date, which allows re-allocation of IP addresses that
are no longer used.
For Base Stations you are advised to use a specific IP address for which there is no
expiry date. To do so, you can use your DHCP management program to reserve the
IP address or a range of IP addresses.
For network devices that require a specific IP address, or for which you do not want
the ‘IP address lease’ to expire, you can use a DHCP Management program to
reserve their IP addresses. This is the case with your Base Stations.
Once a range of IP addresses has been reserved, you can use the values in this
range to assign to your BreezeNET system.
The Unique Identifier is the Media Access Control (MAC) address for the DHCP
Client. The Client Name should be the computer name for the DHCP Client.
However, this name is used for identification purposes in the DHCP Manager
interface and, therefore, does not have to be and will not affect the actual computer
name.
To see which IP addresses are still available, your DHCP Management program will
usually include a ‘Scope Active Leases’ option. This option allows you to see which
DHCP Clients have leased an IP address from the DHCP Server.
E
Encryption
A security feature for Base Station and BreezeNET stations that enables you to
encrypt data that is transmitted via the wireless medium.
BreezeNET products are optionally available with a factory-installed encryption chip
that is based the WEP encryption algorithm.
To use encryption in your wireless network, all BreezeNET stations and access
points must have the encryption feature installed and set to ‘Enable’. All Base
Station and BreezeNET devices in the network environment must use the same
encryption key.
The encryption key consists of 16 hexadecimal numbers in the range 0-9, A-F. The
second digit of each pair must be even (0,2,4,6,8,A,C,E).
Enterprise-wide Network
A network configuration that has the scale of a corporate LAN. This type of network
may include network segments in different departments, interconnected by means
of bridges and routers. When the network comprises gateways, routers or bridges,
each network device must be identified by a unique IP address. The network may
extend to wireless networking in different buildings, where the buildings are
connected by a wired link, e.g. a leased line.
