Hi all,

The problem is interface , it losted connection for 1 or 2 second each minute rx packet 0 but don’t have error packet or flap port.

In rx Stats or tx Stats, no error. Changed cable cat 6, changed more port but same problem.

Firmware versione 6.24

Please paste here your interface configuration to understand your settings. If you want connect both RB1000s you don’t need to create any bridge.
