Configurations from the scenarios below are examples that demonstrate the potential capabilities of Infinet devices. The configuration may change depending on the model and firmware version. Do not recommend copying the solution data to the hardware without checking. |
Description
Infinet R5000 devices Devices of InfiLINK 2x2 and InfiMAN 2x2 families have a functional redundancy of the channels. A hot standby 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 devices through both links.
The principle of operation is extremely simple. The Infinet 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 standby 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 the monitored MAC-address appears in the primary link.
You can provide the redundancy for the link via XG devices with using R5000 InfiLINK 2x2 and InfiMAN 2x2 family devices.
