I unplugged a network cable in my redundant network, then plugged it back in, but redundancy wasn’t restored. What’s wrong?

Dante redundancy requires that both the primary and secondary interfaces on any redundant device are connected using the same link speed.For example, if the primary interface is connected to a 1 Gbps switch port, the secondary interface must also be connected to a 1 Gbps switch port. Similarly, if the primary interface is connected to a 100 Mbps switch port, the secondary interface must also be connected to a 100 Mbps switch port.If the primary and secondary interfaces for any device are connected to ports of different speeds, redundancy will not function properly for that device.
