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

MassimilianoDelta · February 27

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:

https://www.zyxel.com/global/en/products/switch/24-48-port-gbe-l3-access-switch-with-6-10g-uplink-xgs2220-series

https://www.zyxel.com/global/en/products/switch/28-port-10gbe-l3-aggregation-switch-xs3800-28

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,
Max

Hi @MassimilianoDelta,

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

Hi,
I tried the Flex Link setup in Zyxel GS2200-10HP and every thing works fine.
Thanks for your great support.

Thanks bye,
Max
