7 Virtual access points configuration
On each wireless interface, you may configure up to 16 virtual access points. Each access point may have
individual name of wireless network (SSID) and type of authentication/authorization. According to the network
scheme given in the figure 1, it is necessary to configure 2 virtual access points on Radio 1 and Radio 2.
Band Steer feature allows clients having opportunity of operation at 2.4 GHz and 5 GHz to set priority of
connection to virtual access points operating at 5 GHz. The followings are necessary for Band Steer feature
operation:
•configure radio interfaces for different frequency ranges;
•create virtual access points (VAP) with the same SSID on each radio interface;
•make sure that the passwords on the access points are the same if you use encryption;
•activate Band Steer parameter on access points.
In «Manage» menu, open «VAP» tab and perform the following:
Configuring Radio 1:
•Radio – select value «1»;
•Enabled – check the boxes for VAP 0 and VAP1.
•VLANID – VLAN number:
•set value «100» for VAP 0;
•set value «1» for VAP 1;
•SSID – wireless network name:
•set value «WorkNetwork» for VAP 0;
•set value «FreeNetwork» for VAP 1;
•StationIsolation – forbid packet transmission among access point's clients. Check the box.
•Band Steer – set a priority of users connection to SSID configured at 5 GHz. Check the box.
•VLANPriority – the 2nd priority level which will be assigned to packets transmitted through the given VAP
from radio environment to wired network.
•Security – secure network mode:
•set «WPAPersonal» value for VAP 0 and set a password for this network connection in «Key» field;
•set value «None» for VAP 1.

9 Cluster operation mode
9.1 Description
The cluster operation mode allows to manage devices in a cluster simultaneously, that sufficiently improves
operation efficiency while deploying, configuring or exploiting a wireless network.
When operating in Cluster mode, it is sufficiently that you configure only one access point. The rest of the access
points will copy the configuration of the device with set parameters. If the configuration of one access point in a
cluster has been changed, the other access points will apply the same changes. The solution is valid while
firmware update. Operation in Cluster mode allows to perform manageable consistent firmware update of devices
in a cluster.
The cluster is a group of devices allocated in a single broadcast domain with synchronized configuration and
firmware. Cluster mode is enabled by default. The defining parameter of the mode is the name of a cluster by
which the identification of device attachment to this cluster is performed. The default name of a cluster is
«default». After loading, WOP-2ac defines if there are devices located on the network with the same name as in its
configuration. If the devices with these parameters are not found, WOP-2ac becomes a master of the cluster. If
the devices belonging to the cluster are found, WOP-2ac starts copying the configuration of a master. Thus, the
first device with enabled Cluster mode occurred on the network becomes a master of its cluster. Other devices
occurred on the network later and having the same cluster name start duplicating the master configuration.
Several clusters with different names might be located in the same network simultaneously. One access point
should be included to only one cluster.
WOP-2ac announces its affiliation to a cluster through a special protocol. The device sends broadcast UDP
packets to LAN with data on affiliation to a particular cluster. Thus, all the access points included to a cluster
exchange data among them, identify a master of the cluster and its configuration. The master carries out an
inventory of the devices in the cluster and always controls the quantity of the access points in the cluster and their
addresses.
9.2 Installation
It is sufficient that only one access point be configured when deploying a network. For providing data exchange
among devices in a cluster, you should install a DHCP server for network addresses distribution.
Network installation algorithm:
1. DHCP server installation.
2. Configuration and physical connection of an access point.
3. Physical connection of other access points in the cluster.
After installing the first access point, you do not need to configure the rest, it is sufficient to connect them
physically to the network. The devices will obtain network addresses, define the master of the «default» cluster
and will be automatically configured according to the master configuration.
9.3 Cluster configuration
The device may operate in a cluster only if WDS (Wireless Distribution System) and WGB (Work Group Bridge)
features are disabled.
For operation in a cluster Management Ethernet interfaces of all access points should be located in one network.
Cluster operation mode is disabled by default.
In «Cluster» menu, open «Access Points» tab and perform the following:

To edit the settings in «Clustering Options» section, switch cluster mode to «Off» state.
In «Clustering Options» menu, perform the following configuration:
•Location – specify physical location of the access point. The option is used to analyse and control the
network in different monitoring tables. «Eltex» is used in the example;
•Cluster Name – set name cluster. The access point will be connected only to a cluster, which name is
specified in «Cluster Name». «default» is used in the example;
•Clustering IP Version – select used IP version for management data exchange among access points in the
cluster. «IPv4» is used in the example.
•Cluster-Priority – set the priority of the device in the cluster. «Eltex» is used in the example;
Click «Update» to save changes.
In «Single IP Management» menu, perform the following configuration:
•Cluster Management Address – specify an address via which the device may access the master cluster.
The master should be located in the same subnet with the cluster. «192.168.10.10» is used in the example.
Click «Update» to save changes.
To enable cluster mode, select «On» in «Clustering» field.

In «Advanced» menu, perform the following configuration:
•Change channels if interference is reduced by at least – select a percentage that the interference must be
reduced by for the access point to change channels. «75%» is used in the example.
•Refresh when access point is added to the cluster – enable re-counting of common spectral structure of
environment and selection of optimal channel for the access point («enable» value) when new access point
is being connected to the cluster.
•Determine if there is better set of channel settings every – set a time interval to schedule updates of
environment spectral structure determination and selection of better channel for the access points. «1Day»
is used in the example.
Click «Update» to save changes.
9.4 Monitoring

To view the statistics, select necessary value and click «Go» in «Display» section. The following parameters might
be viewed:
•AP Location – access point's location. The value is obtained from location description on «Basic Settings»
tab;
•User MAC – MAC address of client's wireless device;
•Idle – average time that the device has been in stand-by mode (when the device does not receive or
transmit data).
•Rate – transmit data rate between an access point and a particular client, in Mbps;
•Signal – a level of signal received from an access point;
•RхTotal – total number of packets received by a client within current session;
•Transmit Total – total number of packets transmitted by a client within current session;
•Error Rate – total number of packets dropped by an access point within current session;
To view correspondence of access points in a cluster and wireless networks detected by these devices, switch to
«Wireless Neighborhood» tab. There is a table, on «Wireless Neighborhood» tab, that shows which wireless
networks are detected by each access point and what signal level each access point accept.

 WOP-2ac quick manual
18
According to this table, spectral analysis of the whole network might be carried out and there is an opportunity to
estimate interference influence to each access point. It will help you to estimate better location of access points
among coverage area and to define locations with exceeding level of noise. The top string of the table contains
data on each radio interface of access points included in a particular cluster. The left column contains data on
wireless networks which are defined by the devices in the cluster. A value of signal level of each access point is
displayed in the top-right cell of the table.
The table is formed in the way that wireless networks organized by a cluster are displayed first, the third-party
networks follow after them.
The table might be displayed in 3 modes:
•In cluster – when checked, the table consists data only on wireless networks organized by the cluster;
•Not in cluster – when checked, the table consists data only on third-party wireless networks;
•Both – when checked, the table consists data on all wireless networks.
To view current list of the access points in the cluster and their parameters, switch to «Radio Resource
Management» tab. The table «Current Channel Assignments» consists the following parameters:
•IP Address – IP address of the access point in the cluster;
•Radio – MAC address of a radio interface of the access point in the cluster;
•Band – standards supported by the radio interface of the access point in the cluster at the moment;
•Channel – number of a channel on which the access point operate;
•Status – operation state of the access point's radio interface in the cluster;
•Locked – block channel change. When checked, the radio interface will always use the same channel even
when another channel is selected as optimal for all the access points in the cluster.
Click «Refresh» to update the table «Current Channel Assignments».

 WOP-2ac quick manual

The table «Proposed Channel Assignments» contains data on available channel values, which the radio interface
will switch to if optimal channel selection has been launched:
•IP Address – IP address of the access point in the cluster;
•Radio – MAC address of a radio interface of the access point in the cluster;
•Proposed Channel – a channel number to which the radio interface will switch when optimal channel
selection is launched.
9.5 Firmware update
The operation in the cluster mode allows to perform automatic firmware update for all the access points in the
cluster without using external systems or controllers. Firmware update might be performed:
•through web interface;
•through DHCP Autoprovisioning (opt 66, opt 67).

 WOP-2ac quick manual

9.5.1 Firmware update via web interface
To update firmware on devices in a cluster through web interface, open «Cluster Firmware Upgrade» tab of an
access point. When updating firmware of devices in a cluster, the firmware file will be loaded to each access point
and set to «Primary Image». Reloading of the devices with new firmware version loading is performed
automatically. The previous firmware version will be saved as «Secondary Image» (backup firmware version).
Perform the following in «Cluster Firmware Upgrade» tab:
•Upload Method – select the firmware loading method for the devices. The loading through TFTP is used in
the example:
•Image Filename – enter a file name of firmware which will be loaded to the device.
•Server IP – enter an IP address of TFTP server on which firmware file is saved. «192.168.15.92» is used in
the given example.
Click «Start-Upgrade» to start updating. While firmware updating, do not switch off the devices and do not update
or change the web page with progress bar.
9.5.2 Firmware updating through DHCP Autoprovisioning
To update firmware, you need a TFTP server and a DHCP server with particular configuration. The updating
process is as follows:
1. An access point is loaded and obtains address via DHCP. The access point obtains 2 parameters from the
server while DHCP session: tftp-server and file name, where tftp-server – an IP address of TFTP server, and
filename is a name of the file with .manifest extension which contains data on the firmware.
2. A master of the cluster, according to received data, starts make attempts to download manifest-file from
TFTP server. After downloading the file, the master compares firmware version specified in a file with its
own. If firmware versions are different, the master downloads firmware file from the TFTP server (file name
of the firmware is specified in manifest-file) and updates automatically.
3. The other devices in the cluster define that the master is not in operation. Then, new master is selected in
the cluster. The device with bigger «uptime» value becomes a master. New master also repeat the second
step: downloads manifest-file, compares firmware versions and updates.
4. The cycle is repeated until all the devices in the cluster are updated.
Update configuration algorithm:
a)Place "wop2.manifest" file on TFTP server, the file should contain the following string:
VERSION= "1.16.0.X"WOP-2ac-1.16.0.X.tar.gz,
whereWOP-2ac-1.16.0.X.tar.gz – name of the archive containing firmware for WOP-2ac;
1.16.0.X – a firmware version included to the archive. The firmware version might be viewed in «version» file in
firmware archive.
b) Place archive with firmware for WOP-2ac on TFTP server.
