Device and config for port failover setup for two identical pcs controller

MassimilianoDelta

I have to configure 2 identical controller PCs in the same rack, the first as master and the second as slave, to manage sensors. They must have the same IP address (identical controller PCs).
I need a failover setup to set up on a single switch/router to make sure the secondary comes online immediately in the event of a master failure and subsequent recovery.
Which device and which configuration do you recommend?
Thanks Max

Hi @MassimilianoDelta,

The "FLEX link" feature might match your purpose, as it is a layer-2 primary and backup link mechanism.

For more information, please reference our switch user's guide Chapter 29 (Page 200).

The switch model that supports this feature:

Please check which switch matches your network and feel free to ask if you have further questions.

Thanks for your support.
I bought a gs2220-10 to test.
I still have a question: how does the switch to know if the master is still working?
with ping? with snmp? other?
Thanks bye,

Hi @MassimilianoDelta,

It is by link. The backup link will take over once the primary link's status turns down.
