About This Chapter
This chapter is comprised of the following sections:
♦
What is BreezeACCESS?, page 1-2, describes the various
products that make up the BreezeACCESS family.
♦
What is BreezeMANAGE?, page 1-3, introduces the functionality
and components of the BreezeMANAGE application.
♦

What is BreezeACCESS?
BreezeACCESS is a broadband wireless access solution optimized for
enhanced IP data and Carrier Class telephony services.
BreezeACCESS is comprised of three product families, as follows:
♦
BreezeACCESS XL: BreezeACCESS XL is available in the licensed
3.5GHz, 3.8GHz and 2.6GHz frequency bands. Employing
Frequency Division Duplex (FDD) mode using wireless packet
data switching technology and Frequency Hopping Code Division
Multiple Access (FH-CDMA) radios, the XL products deliver
exceptional capacity and coverage, and multiple classes of service.
♦
BreezeACCESS MMDS: BreezeACCESS MMDS operates in the
2.5 to 2.686GHz frequency bands in Time Division Duplex (TDD)
mode and employs Frequency Hopping technologies.
BreezeACCESS MMDS ensures a more efficient usage of the
existing spectrum since a contiguous spectrum is not required,
enabling the use of separated MMDS and ITFS channels.
♦
BreezeACCESS II: BreezeACCESS II operates in the 2.4GHz ISM
band, which is unlicensed in most countries. BreezeACCESS II
employs Frequency Hopping Spread Spectrum radios and
operates in Time Division Duplex (TDD) mode.
Introducing BreezeMANAGE
1-3
What is BreezeMANAGE?
The BreezeMANAGE network management system is an SNMP-based
application that enables you to configure, manage and monitor
performance statistics from all BreezeACCESS units deployed in the
network, from a single central management station.
BreezeMANAGE operates in conjunction with the SNMPc Network
Management Platform from Castle Rock Computing, and with HP
OpenView.
Introducing BreezeMANAGE

BreezeMANAGE Features
and Benefits
BreezeMANAGE includes the following featured functionality:
♦
The BreezeMANAGE graphical user interface enables you to view,
modify and configure the parameter sets of each managed unit, as
well as view the current status of the unit’s configuration and
performance. Using a standard selection of windows, drop-down
menus, action buttons and interactive fields, the interface
provides an intuitive and logical workflow.
♦
BreezeMANAGE delivers a detailed graphical overview of the entire
network. Through an at-a-glance map, BreezeMANAGE enables
you to define and logically layout the network structure. Providing
multiple map levels, BreezeMANAGE enables you to drill down
into the hierarchical network structure and view specific
information regarding each Access, Subscriber and GPS unit that
comprises the overall network. The map includes color-coding for
device status indication.
♦
BreezeMANAGE provides real-time performance statistics for each
managed unit and enables the remote activation of various
performance tests.
Introducing BreezeMANAGE
1-5
MIBs
The Network Management System communicates with managed
network units using Simple Network Management Protocol (SNMP).
Each managed unit includes an SNMP agent that supports a
Management Information Base (MIB).
Embedded in each unit are the Alvarion proprietary MIBs, which
enhance the SNMP management process. All functions can be
accessed through the Alvarion MIBs using an SNMP application. For
more information regarding the content of the Alvarion MIBs, refer to
the System Manual.
BreezeACCESS agents support the following MIBs.
♦
MIB-II (RFC1213)
♦
BRIDGE-MIB (RFC1286)

Configuring SNMP Settings
The SNMP Community settings are a security mechanism designed to
prevent unauthorized access to managed devices.
The SNMP Community settings for BreezeACCESS devices must be
configured both locally at the device and in the BreezeMANAGE
application. These configurations must match.
To view the SNMP Community settings defined in
BreezeMANAGE:
From the SNMPc Tools menu, select Node Configuration. The Node
Configuration File window is displayed, as shown below.
Figure 2-2: Node Configuration File Window
Getting Started with BreezeMANAGE
2-11
The Node Configuration File window provides a list of network devices
that are registered at the BreezeMANAGE station, based on their
SNMP Community settings. The default settings always appear at the
top of the table and are applied to all devices that are not specifically
registered in the Alvarion node configuration list.
To register a device in the Alvarion node configuration list:
1
In the Node Configuration File window, from the Node menu, select
Add. The Add Node window is displayed.
2
In the Node field, enter the IP address of the device to be
registered.
3
In the Community field, enter the SNMP Read Community string.
4
In the Set Community field, enter the SNMP Read/Write
Community string.
5
Click OK to save the settings and close the Add Node window.
NOTE:
The SNMP Community strings must match those defined locally at the device.
To edit the default SNMP Community settings:
The default SNMP Community settings are applied to all devices not
specifically registered in the Alvarion node configuration list. These
settings appear at the top of the table in the Node Configuration File
window.
To edit the default SNMP Community settings, in the Node
Configuration File window, from the Node menu, select Edit. A
window similar to the Add Node window is displayed, containing the
current settings. Edit the settings as required and click OK to save
the modifications and close the window.

About This Chapter
Many of the configuration parameters provided by BreezeMANAGE
are dependent on the type of device that is being configured and its
frequency band. This means that there are different windows and
parameters depending on whether an Access Unit or Subscriber Unit
is selected and whether you are configuring a BreezeACCESS XL, II or
MMDS network. In addition, units with voice support and GPS
comprise additional parameters and windows. Each parameter is
described according to the applicable unit type and frequency band,

The VLAN Support window is comprised of the following components:
♦
Ethernet Link Type (AU and SU only): Click the up and down
arrows to select the functionality of the unit's VLAN-aware
capability, from the following options:
Access Link, which is available to SUs only, transfers frames
while tagging/untagging them since all devices connected to it
are VLAN-unaware. The unit cannot transfer tagged frames.
Trunk Link, which means that the unit only transfers tagged
frames, since all devices connected to it are VLAN-aware.
Hybrid Link, which means that the device transfers both
tagged and untagged frames since the devices connected to it
can be either VLAN-aware or VLAN-unaware.
♦
VLAN ID - Data (SU only): Enter the number that represents the
VLAN ID for data frames, which identifies the VLAN to which the
Subscriber Unit belongs. The available values range from 1 to
4094.
♦
VLAN ID - Management: Enter the number that represents the
VLAN ID that identifies remote stations for management
purposes. This applies to all applications using SNMP, TFTP,
