It is recommended to use the iPoll 2 proprietary protocol for simple Point-to-Point network configuration.

Perform the following steps to create a simple Point-to-Point link between Access Point iPoll 2 and Station (WDS/iPoll 2):

Step 1. Access Point iPoll 2 Configuration. Change the device’s default IP address (can be static or dynamic) and enable IP alias (secondary IP), if necessary:

Ligo-DLB-AP-MAIN-IP

Step 2. Configure the wireless settings for Access Point iPoll 2:

  • set Wireless mode to Access Point (iPoll 2);
  • set Channel to Auto;
All other settings should be left as their default values.
Ligo-DLB-AP-MAIN
Press the gear icon found in the Wireless Settings (AP) section (shown below) to change the SSID and the encryption configurations.
 Ligo-DLB-STA-AP-MAIN-SSID-SECTION
  • set the SSID;
  • enable Security for secure traffic on link.
All other settings should be left as their default values.

Step 3. Station iPoll 2 Configuration. Change the device’s default IP address (can be static or dynamic) and enable IP alias (secondary IP), if necessary:

Ligo-DLB-STA-MAIN-IP1

Step 4. Configure the wireless settings for Station iPoll:

  • set Wireless mode to Station (WDS/iPoll 2).

All other settings should be left as their default values.

Ligo-DLB-STA-MAIN1
Press the gear icon found in the Wireless Settings (Station) section (shown below) to change the SSID and the encryption configurations.
Ligo-DLB-STA-MAIN-SSID-SECTION
  • set the SSID or use Scan to find iPoll 2 Access Points automatically;
  • enable Security for secure traffic on link.

All other settings should be left as their default values.

Ligo-DLB-STA-MAIN-SSID
Note that Station iPoll 2 security settings must match the settings configured on the Access Point iPoll 2 with which the station is associated.

Step 5. It is highly recommended to change the default administrator’s password for each unit:

Ligo-DLB-MAIN-ADMIN1
Ligo-DLB-MAIN-PASSWORD
Step 6. Verify the PTP link connection. Navigate to Status > Information. The information page will display data for the wireless link.

Access Point iPoll 2’s status page should indicate that one peer (Station iPoll 2) is connected and should provide information about the connection as follows:

Ligo-DLB-AP-MAIN-STATISTICS

Detailed information about the connected peers is found in the Status > Wireless page.

Ligo-DLB-AP-MAIN-STATISTICS3

Station iPoll 2’s status should show up as Connected and there should be progress bars indicating the quality of the connection:

Configuration of a Point-to-Multipoint Bridged Network
WDS or iPoll 2 modes can be set in a bridged (layer 2) network. iPoll 2 mode should be used when the AP and all of its stations are Deliberant devices. Otherwise, select the WDS mode. The recommended maximum number of stations per AP is 60–70.
Configuration of WDS Mode
Change the device’s IP address (can be static or dynamic) and enable IP alias (secondary IP), if necessary. The Default IP address can be left as its default value because it is used for device management.

Steps for configuring the wireless settings for an 11n AP:

  • set Wireless mode to Access Point (auto WDS);
  • choose IEEE mode: use N, if 802.11n-capable radios are used; use A/N mixed or B/G/N mixed, if legacy radios are used on the network;
  • set Channel to Auto;
  • set ACK timeout based on the maximum distance from the station.
Ligo-DLB-APWDS-PTMP-MODE-ACk1
  • set the SSID;
  • enable Security, if necessary.

Ligo-DLB-AP-MAIN-SSID

Configuration of the iPoll 3 Mode

Steps for configuring the wireless settings for an iPoll 3 Master Device:

  • set Wireless mode to Access Point (iPoll 3);
  • set the SSID;
  • set Channel to Auto;
  • enable Security, if necessary.

All other settings should be left as their default values.

Station Configuration
Change the device’s IP address (can be static or dynamic) and enable IP alias (secondary IP), if necessary. All of the stations’ IPs must be on the same subnet as the AP.
Change the second device’s IP address (can be static or dynamic) and enable IP alias (secondary IP), if necessary.

Steps for configuring the Wireless tab on the Station:

based on the access point:

  • select Country;
  • set Wireless mode to Station (WDS/iPoll 2/iPoll 3).
Leave all other settings as their default values.
  • enable Security, if necessary;
  • set the SSID.
Ligo-DLB-STA-MAIN-SSID
Monitor the indicator on the access point to confirm that all stations are connected.
Monitor signal levels on both the Access Point and the Station. The recommended signal level range is –35dBm to –60dBm.

If the device is MIMO, there are two signal streams. One of them is Main (Antenna 1) and the other is Aux. Main’s stream is mandatory. If Main’s signal is very weak, the link will not be stable or will not work at all. It is necessary to align the antennas to achieve the best Main signal. If Aux’s stream is weak, the link will work at a lower data rate. Check whether the CCQ is good on the AP and the Station and whether it reaches 100/100.

Step 6. Optimize the channel size for best performance.

Before changing from auto-channel to some particular channel, it is recommended to perform a scan on the AP and on the Station (Tools > Site Survey). Try to find the cleanest frequency for device operation.

The Wireless Access Control List is an access control based on MAC addresses (only available in AP and iPoll 2 AP wireless modes). Access control allows users to limit wireless associations (based on the MAC address) with APs by creating an Access Control List (ACL).

The Wireless Access Control List is found in the Wireless AP settings:

Ligo-DLB-STA-AP-MAIN-SSID-SECTION

To add a new rule, press Add:

  • Open – no rules are applied.
  • Allow MAC in the list – select to allow connectivity for devices in the list only (white list).

LIGO-DLB-WACL-ALLOW

Deny MAC in the list – select to prohibit connection for devices in the list (black list).

LIGO-DLB-WACL-DENNY

Do not forget to tick the highlighted check mark to save the MAC address in list.

Virtual Local Area Networks (VLANs) are logical groupings of network resources.

  • Enable management VLAN – enable VLAN tagging for management traffic. Access to the AP for management purposes can be further limited using VLAN tagging. By defining Management VLAN, the device will only accept management frames that have the appropriate Management VLAN ID. All other frames using any management protocol will be rejected.
  • Management VLAN ID – specify the VLAN ID [2-4095]. When the device’s interfaces are configured using a specific VLAN ID value, only management frames that match the configured VLAN ID will be accepted by the device.

LIGO-DLB-MANAGEMENT-VLAN1

When users specify new management VLAN parameters, the HTTP connection with the device will is lost. For this reason, users should have a connection between the management station and a port using the new management VLAN or should connect to the new management VLAN using a multi-VLAN router.
Network management is only available on the Bridge network mode.

Map to data VLAN ID – specify the VLAN ID for traffic tagging on particular radio interfaces. Station devices that associate using the particular SSID will be grouped into this VLAN.

LIGO-DLB-DATA-VLAN

Management over wireless – controls wireless administrative access. For security reasons, it is recommended to disable wireless access and, instead, to require a physical network connection using an Ethernet cable for administrative access to the APC. Management over wireless is set up appropriately depending on whether management VLAN is enabled or not.

Enable Wireless VLAN ID on the Station device to enable data VLAN.

LIGO-DLB-STATION-data-vlan

Step 1. Navigate to Configuration > Wireless configuration and set Operating mode to Station (auto iPoll 2).

Ligo-dlb-station-router

Step 2. Click on the little gear icon in the Wireless settings (station) table. In the newly popped-up window, specify the Security parameters for the AP and check whether all of the necessary settings match those of the AP, and then click Done:

Step 3. Verify the connection. Navigate to Status > Information. The information page will display wireless information on the link with access point. The connection status should be Connected and progress bars indicating the quality of the connection should be present:

Ligo-DLB-STA-MAIN-STATISTICS2

Router IPv4 Mode

Step 1. This section allows users to customize the parameters of the Router to suit the needs of the network. This includes the ability to use the built-in DHCP server. When the device is configured to operate as a Router, the following sections should be specified: WAN network settings, LAN network settings, and LAN DHCP settings.

Ligo-dlb-station-router-Ipv4

Step 2. WAN Settings. WAN network settings include options related to the WAN interface. In this scenario, the WAN interface is on the wireless side. The access type of the WAN interface can be configured to use Static IP or Dynamic IP.

WAN mode – set the IP method to Static to specify IP settings for the device’s WAN interface:

Ligo-dlb-station-router-wan2

Set a static IP that belongs to the same subnet as the AP device. Only then can users reach the station from their network.

Step 3. DHCP mode – set up a server to enable the DHCP server on the LAN interface.

Ligo-dlb-station-router-Ipv4-DHCP1

In the IP address field, enter the address which users can use to reach a device via a wired LAN.
  • 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 the DHCP gateway IP address.
  • Lease time – specify the expiration time in seconds for the IP address to be assigned by the DHCP server.
  • DNS server – specify the DNS server’s IP address on the WAN side.
Router IPv6 Mode

Step 1. To set up an IPv6 router, set the Network mode to Router IPv6 and specify the required WAN and LAN settings.

Ligo-dlb-station-router-IPv6

Step 2. WAN Settings.

WAN network settings include options related to the WAN interface. In this scenario, the WAN interface is on the wireless side. The access type of the WAN interface can be configured to use Dynamic stateless IPv6, Dynamic stateful IPv6, and Static IPv6.

WAN mode – set the IP method to Static IPv6 to specify IPv6 settings for the device’s WAN interface:

IPv6 WAN (wired) settings: Static. All settings must be specified manually with this method.

IPv6 WAN (wired) settings: Dynamic Stateless. With this method, the device generates its own IP address by using a combination of locally available information and router advertisements, but receives DNS server information from a DHCPv6 server. The IP address is dynamic.

IPv6 WAN (wired) settings: Dynamic Stateful. With this method, the device obtains an interface address, configuration information (such as DNS server information), and other parameters from a DHCPv6 server. The IP address is dynamic.

Ligo-dlb-station-router-IPv6-WAN

  • IPv6 address – specify the IPv6 address for the Deliberant interface.
  • IPv6 prefix length – enter the prefix length for the address (default is 64).
  • IPv6 default gateway – specify IPv6 address for default gateway.
  • IPv6 DNS server – specify the Domain Naming Server IPv6 addresses.
Set the static IPv6 address belonging to the same subnet as the AP device. This way users can reach the station from their network.

Step 3. DHCPv6 mode. Set up a server to enable the DHCPv6 server on the LAN interface.

 

Ligo-dlb-station-router-IPv6-DHCP1

In the IP address field, indicate an IP address with which the user can reach the devices via a wired LAN.

    • Disabled – select to disable the DHCPv6 server. No IPv6 addresses will be assigned to clients.
    • Dynamic stateless IP – select for automatic IPv6 address configuration.
    • Dynamic stateful IP – select to configure a stateful DHCPv6 server for the LAN by specifying the local DHCP IPv6 address pools, so that the DHCPv6 server can control the allocation of IPv6 addresses in the LAN.
  • IPv6 address from – enter the start IP address. This address specifies the first of the contiguous addresses in the IP address pool.
  • IPv6 address to – enter the end IP address. This address specifies the last of the contiguous addresses in the IP address pool.
  • Lease time – specify the expiration time in seconds for the IP address assigned by the DHCPv6 server.
How to Configure a PPPoE Client?

A DLB APC operating in Router mode will receive Internet data through the WAN port and will share it to the LAN ports, which will be separated by a different IP range. The type of connection to the WAN interface can be set by choosing Static IP, DHCP client, or PPPoE.

WAN mode – choose PPPoE to configure the WAN interface, so that it would connect to an ISP via a PPPoE.

In Access Point mode, the WAN will be on the Ethernet side, while in Station mode, the WAN will be on the Radio interface.

The username and password should be added to the main configuration, while all other settings should remain as their default values.

Failover SSID

LigoDLB units can connect to a pre-configured failover SSID in case the connection to the primary SSID is lost.

In case the Station is operating on a failover SSID and then loses this connection, the Station will try to connect to the primary SSID first, and only then will it try to attempt to connect to the failover SSID. The same sequence of events may also cause a reboot.

Use the Primary SSID tab to specify the Main Access Point SSID.

ssid_failover

Use the Failover SSID tab to enable the SSID failover function.

ssid_failover2

  • Failover SSID – specify the secondary SSID where the LigoDLB Station will try to connect.
  • Return to primary SSID – when enabled, the LigoDLB unit tries to connect continuously to the primary SSID in the intervals preset.
  • Failover timeout – specify the amount of time in minutes for the station to attempt to connect to the primary SSID.
  • Bandwidth limitation:
    • Outgoing (AP to Station) – specify the maximum speed in Mbps of outgoing traffic.
    • Incoming (Station to AP) – specify the maximum speed in Mbps of incoming traffic.

Setup Example:

ssid_failover3

iPoll is a superior upgrade to the standard HCF (Hybrid Coordinate Function) technique. Without iPoll, any device will
transmit data without timing and coordination. HCF will cause frequent collisions when CPEs are sending data to the same
AP. Each collision will cause a random backoff timer before the CPEs can transmit data again. Multiple collisions will cause
a major drop in throughput and performance for the entire network. iPoll overcomes these common problems and yields
drastically better performance results in the same situation compared to standard HCF technology based networks.

The proprietary iPoll protocol allows each wireless link to obtain maximum bandwidth with the lowest possible latency. This is accomplished by utilising a smart polling feature which handles connected clients’ activity. Stations, which require less airtime are moved to a low activity or idle list, while stations, which are generating more traffic are moved to an active list. By decreasing the number of polled stations we achieve lower latency figures as well as higher throughput per station. The uplink/downlink ratio is implemented to control the throughput from the access point to stations. This ratio is dynamic and adjusts based on the active number of stations. The dynamic uplink/downlink ratio together with QoS makes LigoDLB device based networks self-optimizing and able to achieve maximum performance in different conditions.

Station Count: Number of stations from which polling rules will be applied

Threshold, Mbps: Aggregate station throughput Mbps from which it will be started to poll

Threshold, PPS: Station PPS from which it will be started to poll

Check Interval, s: Thresholds checking interval in seconds

How to use polling parameters for PTP to get max capacity and low latency
