Edit_Redundancy with Failover option

CAUTION

Configurations from the scenarios below are examples that demonstrate the potential capabilities of the InfiNet 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.

Description

InfiLINK 2x2 and InfiMAN 2x2 families units have a functional channels redundancy function. A hot reserve might be created by using the Failover option. The Failover option does not depend on the method of data transmission on the main channel.The only condition is connectivity at level 2 between InfiNet Wireless devices through both links.

The principle of operation is extremely simple. The InfiNet Wireless device, on which the Failover option is configured, checks the availability of a specific MAC address through the primary link. If this MAC address is available, then the operation of the backup channel is blocked. The radio module stops broadcasting on the backup master. The reserved slave device only listens to the radio while there is no signal from the master. Thus, the backup link can operate on the same frequency as the main one, but it does not have any influence on it. As soon as the monitored MAC address disappears in the main link, the backup link will be unlocked and traffic will begin to be transmitted over it. The process is completely automatic. However, the transition to a backup link is associated with a short-term idle time. Traffic will return automatically to the primary link as soon as reserve link is failure.
If InfiLINK 2x2 and InfiMAN 2x2 families devices are used as the main link, this gives additional advantages. In this case, both radio links can be configured with the Failover option. For both communication channels, the quality of the established connection will be automatically evaluated. Connection with the worst indicators will automatically become a backup channel. The channel selection parameters can be controlled manually.
You can also install two InfiNet Wireless devices with a single external antenna connection or similar frequency.

1а) Manual MAC address selection

1b) Manual MAC address selection with joining devices into a single MINT area (different switch group identificators are used on main and backup links)

1c) Manual MAC address selection with joining devices into a single MINT area (RF- and PRF-interfaces are not joined on Slave 2)

2) Automatic MAC address selection

Configuration of Failover in WANFlex

mint IFNAME [-]failover {MAC|auto}

Command	Description
mint IFNAME failover MAC	Configure Failover option to check "MAC" availability
mint IFNAME failover auto	Configure Failover option to check "MAC" availability. "MAC" will be selected in automatic mode
mint IFNAME [-]failover	Disable Failover

Configuration Example

A management is VLAN 100 inside a switch group #100. A transport of user data is inside a switch group #1.

CAUTION

STP protocol may block correct working Failover option, so it should be disabled. Failover option causes short-time loops in one broadcast domain.

Configure Master 1 and Slave 1 as the main link.

Configure switch groups
CAUTION

For the schemes 1a and 1c, switch groups with the same identificators can be used on Master 1 - Slave 1 and Master 2 - Slave 2 links.
Master 1
```
switch group 1 add eth0 rf5.0 
switch group 1 start
```
Slave 1
```
switch group 1 add eth0 rf5.0 
switch group 1 start 
```
Master 2
```
switch group 1 add eth0 rf5.0 
switch group 1 start
```
Slave 2
```
switch group 1 add eth0 rf5.0 
switch group 1 start 
```
CAUTION

For the schemes 1b and 2, the switch group identificator for the data transmission on Master 2 and Slave 2 must differ from the group identificator on Master1 and Slave 1, or it might cause the loop.
Master 1
```
switch group 1 add eth0 rf5.0 
switch group 1 start
```
Slave 1
```
switch group 1 add eth0 rf5.0 
switch group 1 start 
```
Master 2
```
switch group 2 add eth0 rf5.0 
switch group 2 start
```
Slave 2
```
switch group 2 add eth0 rf5.0 
switch group 2 start 
```

Enable Failover option.
1a) Manual MAC address selection (configurations for 1b and 1c are equal)
Master 2
```
mint rf5.0 failover "MAC Slave 1"
```
2) Automatic MAC address selection
Master 1
```
mint rf5.0 failover auto
```
Master 2
```
mint rf5.0 failover auto
```
Make one of the links as backup.
CAUTION

The backup link must be defined manually when both costs of the radio links are equal.
Master 2
```
mint rf5.0 -extracost 3000
```
Slave 2
```
mint rf5.0 -extracost 3000
```
