The multicast setting can be turned on or off on Ethernet an[...]

P-661H-D Series Support Notes Fairness-Based is chosen, then the bandwidth is allocated by ratio. Which means if A class needs 300 kbps, B cla ss needs 600 kbps, then the ratio of A and B's actual bandwidth is 1: 2. So if we get 450 kbps in total, then A would get 150 kbps, B would get 300 kbps. We select Priority-Based in this example. Key Se[...]
