Could you elaborate your intention, Netmaster Class?

I’m sorry, although I’m still confused on the calculations.

Would you consider explaining that in more depth if possible.

This seems to be one of the concepts that i can’t get my arms around

The last example is a bit wonky. It’s clear from the config and the maths that the interface speed is 10Mbps, but you’ve got 100Mbps listed at the bottom of the table. Cheers.

don’t understand why “1000Kbps + 200 Kbps + 1200 Kbps + 400Kbps = 2Mbps” on last line
I would think queue 1 has 200kbps only….
