I'm having a communication problem between an Omnitik and an RB3011, both connected via twisted pair. However, after a power outage, communication between them stopped, and I was testing changing the speed on the interface, which was in auto-negotiation mode. I tested everything, and when I selected 100M baseFX full, a warning appeared stating that the speed was unsupported, but the Omnitik communicated with the RB via the twisted pair.

When the Omnitik restarts, auto-negotiation works again, and it's back to 100M baseT full.

Does anyone know why this happens?
