In order to double the throughput of the Quanta based systems, the aggregation technology can be used based on the standard protocols of third-party equipment or AstraMUX switches. The simplest scheme will be the organization of two links established at the 2 level of OSI via two Quanta devices. LACP protocol excludes loops and allows to double the throughput in compare to the perfomance of the single link.
In this case, the link aggregation is configured on the switches using the LACP protocol. These can be both AstraMUX switches or third-party equipment. Traffic will be balanced between the two links, increasing their total throughput.
Additionally in case one of the links is breaking up, traffic will be completely transferred to the second link.
NOTE
The device management and monitoring are not possible in the described configuration. In order to retain the ability to manage devices, use the configuration method described in the "Management in LAG" section.
Unfortunately, in this case, the use of one frequency for two pairs of devices is not desirable.
CAUTION
Configurations from the scenarios below are examples that demonstrate the potential capabilities of the Astra Wireless devices. The configurations may vary depending on the model and firmware version. We do not recommend copying this solutions to the hardware without checking.
Step 1: Configure Master 1 and Slave 1 devices as the first radio link using the following parameters:
Downlink center frequency: 5055 MHz;
Uplink center frequency: 5055 MHz (Master only);
Channel width: 40 MHz;
Frame length: 5ms;
Access key: 9876.
Step 2: Configure Master 2 and Slave 2 as the second radio link using the following parameters:
Downlink center frequency: 5155 MHz;
Uplink center frequency: 5155 MHz (Master only);
Channel width: 40 MHz;
Frame length: 5ms;
Access key: 6789.
Step 3a: Configure LACP on the AstraMUX switches.
AstraMUX 1 / AstraMUX 2
Step 3b: Configure LACP on the third-party equipment (not included in the example).
NOTE
This scheme can be implemented only when using AstraMUX switches, the configuration can not be applied for third-party switches.
VLAN 100 is allocated for device management.
VLAN 200 is allocated for the traffic transmission. All data traffic will be encapsulated in PRF (including VLAN 100) and forwarded unchanged in VLAN 200 from AstraMUX 1 to AstraMUX 2. VLAN 200 is used only on the network part between AstraMUX 1 and AstraMUX 2, its use in the rest of the network is not prohibited.
To prevent a loop VLAN 100 transmission over the radio must be disabled.
Step 1: To transmit VLAN 100, create the vlan100.1 interface over the eth1 physical interface (toward the device of the first radio link), the vlan100.2 interface over the eth2 physical interface (toward the device of the second radio link).
Step 2: To transmit VLAN 200, create the vlan200.1 interface over the eth1 physical interface, the vlan200.2 interface over the eth2 physical interface.
Step 3: Join the vlan200.1 and vlan200.2 interfaces using the LACP protocol.
Step 4: Create the PRF interface over the lag0 parent interface.
Step 5: Create a switch group 100 for management purpose.
Step 5a: If management is organized in a global native VLAN, the group should contain the eth0 interface, the prf interface to transfer data traffic, and the vlan100.1 and vlan100.2 interfaces to manage radio devices. Create an svi100 interface to manage the AstraMUX switch, assign it an IP-address allocated for management.
Step 5b: If management is organized in a certain dedicated VLAN, for example VLAN 600, create an interface for operations with the specified VLAN. The group should contain the vlan600 interface, the prf interface to transfer data traffic, and the vlan100.1 and vlan100.2 interfaces to manage radio devices. Create an svi100 interface to manage the AstraMUX switch, assign it an IP-address allocated for management.
Step 6: To transmit transit traffic, create switch group 200.
Step 7: Configure the second AstraMUX switch in the same way.
Step 1: Set wireless links between Master 1 - Slave 1 and Master 2 - Slave 2 devices.
Step 2: At the "Network" set the IP address allocated for the device, associate VLAN 100 with it.
Step 3: In the "Switch" section, allow VLAN 200 transmission between the ge0 and radio interfaces. Allow management in VLAN 100 for interface ge0. Note that transmissionover the radion of VLAN 100 and the default VLAN used for local configuration must be disabled. Management in VLAN 200 must be disabled also.
Step 4: Configure all radio devices in the same way.
