I'm now having a problem where I'm not entirely sure whether I misunderstood the manpage or there is a bug in the parsing. I fell about some errors converting a small subset of our packeteer rules to pf. I created a testcase with the following config altq on vr1 hfsc bandwidth 5000001b queue { 1, 9999 } queue 1 hfsc(red, realtime 5000000b, upperlimit 5000000b) { 2 } queue 2 hfsc(red, realtime 4900000b, upperlimit 5000000b) { 3 } queue 3 hfsc(red, realtime 4800000b, upperlimit 5000000b) { 4 } queue 4 hfsc(red, realtime 4700000b, upperlimit 5000000b) queue 9999 hfsc(default, red, realtime 0b, upperlimit 5000000b) when loading I get pfctl: real-time sc exceeds the interface bandwidth pf.conf:3: errors in queue definition apparently when using subqueues pf adds up the realtime bandwidth of all queues and compares it to the interface bandwidth. To my understanding the sum of the bandwidth of all child queues should be compared to the direct parent queue. Am I wrong here? Of course I could increase the bandwidth parameter on vr1 to something really hillariously high, but is this the thing intended? Bernhard
