The auxiliary paths are configured at eth3 and eth5
So, when we start our failover, it automatically configures eth0 as a third auxiliary path. But only on the secondary server.
I can't find any configuration mismatch on the servers.
In the failover screen, it says that the primary server uses eth3 and eht5 and the service is OK.
At the secound server it says eth3, eth5, and eth0 is used, with a failed connection on eth0 and a degraded failover service.
