Configured Rate Effect
In the following table the configured rates total less than the available bandwidth and maximize
bandwidth usage is disabled, both servers get their configured rate.
Table 123 Configured Rate Effect

Priority Effect
Here the configured rates total more than the available bandwidth. Because server A has higher
priority, it gets up to it's configured rate (800 kbps), leaving only 200 kbps for server B.
Table 124 Priority Effect

Maximize Bandwidth Usage Effect
With maximize bandwidth usage enabled, after each server gets its configured rate, the rest of the
available bandwidth is divided equally between the two. So server A gets its configured rate of 300
kbps and server B gets its configured rate of 200 kbps. Then the ZyWALL divides the remaining
bandwidth (1000 - 500 = 500) equally between the two (500 / 2 = 250 kbps for each). The priority
has no effect on how much of the unused bandwidth each server gets.
So server A gets its configured rate of 300 kbps plus 250 kbps for a total of 550 kbps. Server B
gets its configured rate of 200 kbps plus 250 kbps for a total of 450 kbps.
