# Redundancy with AstraMUX
{% hint style="danger" %}
**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.
{% endhint %}
### Description
Link aggregation of radio channels allows increasing the maximum radio throughput. AstraMUX switches can aggregate radio links into a single MINT domain where a capacity of each link will be estimated in real time.
### Configuration Example
A management is VLAN 100 in switch group #100. A transport of user data is in switch group #1.
#### Configure Master 1 and Slave 1 as the main link.
**Master 1**
```

```
**Slave 1**

#### Configure switch groups.
{% hint style="danger" %}
**CAUTION**
The switching group number for the data transmission on Master 2 and Slave 2 must differ from the group number on Master1 and Slave 1, or it might cause the loop.
{% endhint %}
**Master 1**
switch group 1 add eth0 prf0
sw group 1 repeater on
switch group 1 start
**Slave 1**
```
switch group 1 add eth0 prf0
sw group 1 repeater on
switch group 1 start
```
**Master 2**
```
switch group 2 add eth0 prf0
sw group 2 repeater on
switch group 2 start
```
**Slave 2**
```
switch group 2 add eth0 prf0
sw group 2 repeater on
switch group 2 start
```
**AstraMUX 1**
```
