I want to deploy the following very simple traffic shaping scenario:
port1---WAN---> High priority
port2---WAN---> Low priority
I have set two shared shapers for that:
High: Traffic priority - High, Max BW = 6000, Guaranteed BW = 2000, DSCP = OFF
Low: Traffic priority = Low, all other settings are OFF
With these settings, a client PC that is browsing from port2 (low priority) is taking all the BW and the high priority traffic is not served.
When I set Max BW at the Low priority shaper, both shapers are served.
I was assuming that when the priority is set to Low to a traffic shaper, all traffic should be put a low priority no matter the bandwidth. Therefore it shouldn't matter if you have set a Max BW or not. However I notice that the Max BW really matters at Low priority shaper.
Can somebody explain to me how the traffic shaper is working at low priority in respect of the Max BW setting? How does the low priority shaper is working, when the Max BW setting is set to OFF?
