I have a point to point that terminates on a 1500D running 5.4.2. This point to point is 50Mbps and I need to run some QoS so I set the interfaxe "outbandwidth" to 50000 and set some traffic shaping policies to prioritize traffic. I noticed that office wasn't making it over 10Mbps so I ran some speed test with my Fluke XG and I can only really get like 7.5 Mbps consistantly. I removed the traffic shaping policies and same result. So I removed the "outbandwidth" command from both sides and now I can get all 50Mbps.
I reapplied the "outbandwidth" to 50000 again and back down to 7.5 Mbps I went. So I increased it by 10Mbps and it would go up a little bit at a time. Till I got to 100000 (100Mbps) and then I was finally getting 50Mbps of throughput.
I tried to go through documentation and I don't see anywhere that suggest that I should be doing 100Mbps to get 50Mbps. Wondering if I have a bug or if anyone else has seen it. I'm working on getting a test setup with another unit but I haven't dont it yet.
