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 single MINT area devices location (different switch group identificators are used on main and backup links)
1c) Manual MAC address selection with single MINT area devices location (RF- and PRF-interfaces have not join on Slave 2 device)
2) Automatic MAC address selection
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.

CAUTION
On schemes 1a and 1c can be used switch groups with the same identificators on Master 1 - Slave 1 and Master 2 - Slave 2 links.
