Step 1. Access Point iPoll configuration: change device’s default IP address (can be static or dynamic), enable IP alias if necessary:
Step 2. Configure wireless settings for Access Point iPoll:
Step 3. Station iPoll configuration: change device’s default IP address (can be static or dynamic), enable IP alias if necessary:
Step 4. Configure wireless settings for Station iPoll:
Step 5. It is highly recommended to change default administrator’s password for each unit:
Step 6. Verify the PTP link connection. Navigate to the Status | Information page. The Information page will display wireless information of the link.
The status page of the Access Point iPoll must indicate that one peer (Station iPoll) is connected and information about connection must be displayed as follows:
The status of the Station iPoll must be displayed as Connected and progress bars indicating the quality of the connection must be displayed:
Point to Multipoint bridged network configuration
Configuration
Access Point Wirelles section configuration steps:
- Select country code
- Select wireless mode: Access point WDS
- Define SSID
- Choose IEEE mode:
- N if you use 802.11n capable radios
- A/N mixed or B/G/N mixed if you also use legacy radios in your network
- Set channel to “Auto”
- Set Max data rate with Auto data rate “Dynamic algorithm”
- Enable Security if necessary
- Set ACK timeout based on the maximum distance from the station
- Leave all other settings as default
Configuration of the stations:
Station Wirelles section configuration steps:
According to access point:
Main stream is mandatory. If main signal is very weak, the link will not be stable or will not work at all. It is necessary, to align the antennas for the best main signal. If Aux stream is weak, the link will work at lower data rate. Check if SNR is good on AP and Station and it is over 20/20.
The HotSpot scenario is popular in the various public places like an airport, shop, bar or stadium. The APC allows user authentication through external or internal Web portal. This authentication method is called UAM. User provides login credentials and then Web portal attempts to authenticate and authorize the client using the provided information. Client will not send any authentication requests directly to the APC, the Web portal will do this. On success, APC will allow access to the Internet; otherwise Web portal will display failure notice.
Follow the steps to configure a Hotspot UAM authentication through external Web portal, for wireless clients.
Step 1. Configure network settings: the HotSpot with UAM authentication is available only if APC operates as Router.
Step 2. Setup wireless settings for HotSpot:
-Setup the External UAM fields: login page URL, welcome page URL, blacklist URL and logout URL
-UAM configuration can be automatically updated from the server at scheduled time
-UAM supports Hotspot description according to WISPr 1.0 recommendation: WISPr location name, operator name, network name, ISO country code, E.164 country code, E.164 area code
-UAM supports traffic limitation and has fields for default bandwidth definition. These parameters/attributes can be overridden per user from the RADIUS.
Step 5. After the UAM authentication is successfully configured on the APC, all wireless clients will be redirected to the External Web portal for authentication.
Virtual AP
Use the Configuration | Virtual AP page to configure to create up to 7 additional Virtual AP interfaces. The Virtual AP defines a logical wireless network, and the APC can be configured to provide additional 7 wireless networks on each device radio. All the VAPs may be active at the same time meaning that client devices can associate to the APC using any of the VAP SSID.
The Virtual AP table displays a summary of all virtual radio interfaces running on the APC:
To create a new Virtual AP, click on + button to add new entry on the VAP table, then select this entry and specify required parameters:
SSID – specify the unique name for the VAP [string].
Broadcast SSID – when this option is selected the particular SSID is visible during network scans on a wireless station. When unselected, the VAP SSID is not visible and not broadcasted to wireless stations.
Quality of service (WMM) – enable to support quality of service for prioritizing traffic.
Client isolation – enable the user Layer 2 isolation. The Layer 2 isolation blocks the wireless clients from communicating with each other.
Max clients limit – specify the maximum number of associated wireless clients per VAP.
Each VAP security is configured by default as an “open system”, which broadcasts a beacon signal including the configured SSID. For more secure network choose one of the security mechanisms for each VAP interface.
Security – choose the wireless security and encryption method from the drop-down list.
VLAN to SSID mapping
Virtual Local Area Networks (VLANs) are logical groupings of network resources.
VLAN to SSID mapping – specify the VLAN ID for traffic tagging on required radio interface [2-4095]. The Station devices that associate using the particular SSID will be grouped into this VLAN. Configuration window is in Configuration/Network section. When device interfaces are configured with a specific VLAN ID value in Management section, only management frames that matching configured VLAN ID will be accepted by device. Restrict management is used when stations have to be management via VLAN too.
Use Access Point Repeater mode in order to extend the range of the existing network infrastructure. The Access Point repeater’s wireless settings has possibility to scan SSID of the surrounding APs and choose the required one. Enable WDS when the main AP is working in WDS mode too. Do not forget to add security information which is needed to connect to main AP. Also country code should be the same on all devices.
Repeater Basic Wireless Settings
SSID – specify the SSID of the remote access point.
Enable/Disable WDS – specifies Access Point Repeater mode WDS or non WDS
Scan – click this button to scan for surrounding wireless networks. Found network SSID’s will be available in drop down menu.
Peer Access Point MAC address – enter the MAC address of the remote access point.
Broadcast SSID – enable or disable the broadcasting of the SSID.
IEEE mode – specify the operating wireless mode.
Channel width – The default channel bandwidth for 802.11 radio is 20MHz. The 802.11n allow channel bonding in such way the total channel width becomes 40MHz.
1. Set wireless mode to Access Point Repeater and go into Peer AP settings
2. Scan and choose AP SSID which is going to be repeated.
3. In Basic and Security sections there could be added the same as main AP SSID and Security information or created new one.
WDS mode should be disabled when main AP is working in regular non WDS mode. Commonly used when trying to repeat simple wireless router.
Traffic Limiting
Use Traffic Shaping to control download or upload bandwidth in order to optimize or guarantee performance. There are two methods to control network traffic:
Limit all traffic – limits overall APC upload and download traffic.
Limit per IP traffic – limits upload and download traffic for a specified IP addresses.
Limit all traffic
Enable download shaping – select to enable limitation of the download traffic.
Download limit, kbps – specify the maximum download bandwidth value in Kbps.
Download burst, kbytes – specify the download burst size in kbytes.
Enable upload shaping – select to enable limitation of the upload traffic.
Upload limit, kbps – specify the maximum upload bandwidth value in Kbps.
Upload burst, kbytes – specify the upload burst size in kbytes
Limit per IP traffic
Use + button to create new traffic limitation rules:
IP address – specify IP address for which the traffic will be limited.
Down rate, kbps – specify the maximum download bandwidth value in Kbps.
Down burst, kbytes – specify the download burst size in kbytes.
UP rate, kbps – specify the maximum upload bandwidth value in Kbps.
UP burst, kbytes – specify the download burst size in kbytes
Setup CPE as a Router
Step 1. Navigate to the Configuration | Wireless tab, choose Station wireless mode, click Scan button near the SSID entry field to choose the SSID of the AP where the station will be associated to. Specify the Security parameters for the AP, check IEEE mode (these settings must conform with AP wireless settings) and click Save&Apply:
Step 2. Verify connection. Navigate to the Status | Information page. The Information page will display wireless information of the link with access point. The connection status must be displayed as Connected and progress bars indicating the quality of the connection must be displayed:
Step 3. Router Mode. This section allows customizing parameters of the Router to suit the needs of network, including ability to use the built-in DHCP server. When device is configured to operate as Router, the following sections should be specified: WAN network settings, LAN network settings and LAN DHCP settings.
Step 4. WAN Settings WAN network settings include settings related to the WAN interface. In this scenario WAN interface is from wireless side. The access type of the WAN interface can be configured as: Static IP, Dynamic IP, PPPoE client. WAN mode – choose Static IP to specify IP settings for device WAN interface:
Step 4. DHCP mode – choose server to enable DHCP server on LAN interface.
IP address from – specify the starting IP address of the DHCP address pool.
IP address to – specify the ending IP address of DHCP address pool.
Subnet mask – specify the subnet mask.
Default gateway – specify DHCP gateway IP address.
Lease time – specify the expiration time in seconds for the IP address assigned by the DHCP server.
DNS server – specify the DNS server IP address.
DHCP Relay configuration example
What is DHCP relay mode? The DHCP relay forwards DHCP messages between subnets with different sublayer broadcast domains.
Step 1. Configure AP as bridge with IP 192.168.11.66 netmask 24, GW 192.168.11.1
Step 2. Configure CPE as a Router and connect It to AP. Setup DHCP mode as relay. Static WAN, wireless IP address is from the same subnet as AP which lets to reach device via wireless. LAN, wired IP address is used to reach device from LAN side and should be from the DHCP server subnet.
How to test on Linux
Step 1. Install DHCP server on your linux pc:
sudo apt-get install isc-dhcp-server
Step 2. Configure DHCP server as following:
Step 3. Step four: configured DHCP server with IP on eth2 interface. IP on eth2: 192.168.11.1 netmask 24, GW 192.168.11.1
Step 4. Step six. Add static route on DHCP server in order to reach x.2.0 LAN with “sudo route add –net 192.168.2.0 netmask 255.255.255.0 gw 192.168.11.1
Step 5. Test the configuration.
How to configure PPPoE client
In router mode the DLB APC will receive internet through WAN port and will share it to the LAN ports that will be separated with a different IP range. The type of connection to the WAN interface can be made by Static IP, DHCP client or PPPoE.
WAN mode – choose PPPoE to configure WAN interface to connect to an ISP via a PPPoE. In main configuration should be added Username, Password all other settings should be left by default:
Parameters explanaition:
MAC address – specify the clone MAC address if required. The ISPs registers the MAC address of the router, and allows only that MAC address to connect to their network. In such case if there is need to change hardware (router), you need to notify your ISP about MAC address change, or simply set the router’s MAC address to the MAC address of the previously router/computer.
VLAN ID – specify the VLAN ID for traffic tagging on required radio interface [2-4095]. The Station devices that associate using the particular SSID will be grouped into this VLAN.
User name – specify the user name for PPPoE.
Password – specify the password for PPPoE.
MTU – specify the MTU (Maximum Transmission Unit). The default value is 1500 bytes.
Reconnect mode – specify PPPoE reconnection mode:
- Always on – PPPoE connection automatically starts without timeout. The router will keep trying to bring up the connection if it is disconnected for some reason.
- On demand – the PPPoE connection automatically starts when there is outbound traffic to the Internet, and it automatically terminates if the connection is idle based on the value specified in the Idle time [1-65535] setting.
DNS settings – allows selecting if automatically assigned or alternative DNS servers should be used.
Enable IP alias – specify the alternative IP address and the netmask for APC unit management.
