These parameters include the guaranteed transmission rate, maximum transmission rate, guaranteed
receiving rate, and maximum receiving rate. The sum of guaranteed rates for all bandwidth levels cannot
exceed the maximum rate of the device. The maximum rate for any bandwidth level cannot exceed the
maximum rate of the device.
To simplify calculation and configuration, QoSM allows you to allocate bandwidth to bandwidth levels
in percentages.
Rate configuration list buttons
• Refresh—Refresh the rate configuration list.
• Details—Recalculate the values in the list. Click this button after the percentage values are changed,
and the system recalculates the values for the guaranteed rate and maximum rate of each
bandwidth level and displays the new values in the input boxes.
• Save—Deploy all parameter settings on the page to the device.
• Back—Return to the QoS Device page.
Configure the following parameters for rate limiting:
• Maximum Tx Rate—Specify the maximum transmission rate for the device.
• Maximum Rx Rate—Specify the maximum receiving rate for the device.
Bandwidth levels are described in a list.
Bandwidth level list contents
• Bandwidth Level—Options are Very High, High, Normal, and Low.
• Tx Rate—Transmission rate for the bandwidth level, including guaranteed rate and maximum rate.
{
Guaranteed—Percentage of the guaranteed transmission rate for the bandwidth level to the
maximum transmission rate of the device. The sum of guaranteed transmission rates for all
bandwidth levels cannot exceed 100%. After you enter a percentage value, the system
automatically calculates a value in kbps for the guaranteed transmission rate and displays the
value behind the input box.
{
Maximum—Percentage of the maximum transmission rate for the bandwidth level to the
maximum transmission rate of the device. The maximum transmission rate for the bandwidth
level cannot exceed 100%. After you enter a percentage value, the system automatically
calculates a rate value in kbps for the maximum transmission rate of the bandwidth level and
displays the value behind the input box.
• Rx Rate—Receiving rate for the bandwidth level, including guaranteed rate and maximum rate.
{
Guaranteed—Percentage of the guaranteed receiving rate for the bandwidth level to the
maximum receiving rate of the device. The sum of guaranteed receiving rates for all bandwidth
levels cannot exceed 100%. After you enter a percentage value, the system automatically
calculates a value in kbps for the guaranteed receiving rate and displays the value behind the
input box.
{
Maximum—Percentage of the maximum receiving rate for the bandwidth level to the maximum
receiving rate of the device. The maximum receiving rate for the bandwidth level cannot exceed
100%. After you enter a percentage value, the system automatically calculates a value in kbps
for the maximum receiving rate of the bandwidth level and displays the value behind the input
box.
