qos

I had a look at replacing a Mikrotik with a Unifi Edgerouter, specificaly looking at QoS and whether one was easier to understand than the other. My conclusion was that the Mikrotik has better visibility with its queue trees, however the process for setting up QoS on the edgerouter is as follows:

One note is that the edgerouter implementation is better at guaranteeing that all traffic will hit the QoS queues, compared to a Mikrotik where packets marked with a new packet mark will go direct to the interface until they are explicitly put into a queue.

I have been looking after QoS settings on a site using a Cisco router for a number of years, and had issues with it not doing what I expected. The design was to use a hierarchy to guarantee bandwidth to certain classes of traffic, but allow all traffic to use the full bandwidth if other classes did not need theirs. I discovered that you need to apply the service-policy to the ATM PVC (for a DSL WIC) in order for it to work as expected, and NOT to the dialer interface. The config I used is below:
