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 channels redundancy functional. 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.
You can provide the redundancy for the link via InfiLINK XG/InfiLINK XG 1000 devices with using InfiLINK 2x2 and InfiMAN 2x2.


Configuration Example

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 a backup link.
