Configuring QoS Bandwidth Control Configuration
Multicast Rate
Mode / Multicast
To enable the multicast rate control, select a multicast rate mode and specify the
upper rate limit for receiving broadcast packets in the Multicast 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 multicast rate control, select Disable in the Multicast field.
UL-Frame Rate
Mode / UL-
Frame
To enable the UL-Frame (Unknown unicast frame) rate control, select a UL-Frame
rate mode and specify the upper rate limit for receiving UL-Frames in the UL-
Frame 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 UL-Frame rate control, select Disable in the UL-Frame field.
LAG Displays the aggregation group which the port is in.
2) Click Apply.
Note:
•
For ports in the same LAG, rate limit / storm control should be set to the same value to ensure
a successful port aggregation.
•
For one port, you cannot enable the Storm Control and the Rate limit at the same time.
