MikroTik have released their version 6.41 of the current build. Whilst there are some new features the most obvious one now is the removal of the master-slave relationship ability to allow hardware switching. MikroTik have done this in a bid to simplify the configuration meaning that now you can use the bridge functionality.
Previously bridging was all done through the CPU so switching on lower end hardware meant that you may not always get full speeds and often ended up with a 100% CPU utilization for a simple file transfer.
MikroTik have now made it so that you can add single, multiple or all ports into a bridge with a check box available to take advantage of the “hardware offload” function. Again, whilst not technically a new feature for the series, it is a redesigned way of achieving hardware switching. The result is a brilliantly clean implementation which resulted in the following from my testing on an older gigabit router.
