To enable the broadcast rate control, select a broadcast rate mode and specify
the upper rate limit for receiving broadcast packets in the Broadcast field. The
packet traffic exceeding the rate will be discarded.
The switch supports the following three rate modes:
kbps: Specify the upper rate limit in kilo-bits per second, which ranges from 1 to
1000000 kbps. This mode is invalid if PPS is enabled.
ratio: Specify the upper rate limit as a percentage of the bandwidth, which ranges
from 1 to 100 percent. This mode is invalid if PPS is enabled.
pps: Specify the upper rate limit in packets per second, which ranges from 1 to
1488000 packets per second. This mode is invalid if PPS is disabled.
To disable the broadcast rate control, select Disable in the Broadcast field.
