Example 3: The RX bandwidth number of the port 5~ port 8 is set to 50, 60, 70, 80 respectively, and Speed base is set to "low". The real bandwidth comes from the formula of 32Kbps*50, 32Kbps*60, 32Kbps*70 and 32Kbps*80 respectively After the "update" button is executed, the real bandwidth will show up in RX fields. (d) High bandwidth for RX Example 4: The RX bandwidth number of the port 5~ port 8 is set to 50, 60, 70, 80 respectively, and Speed base is set to "high". The real bandwidth comes from the formula of 32Kbps*50, 32Kbps*60, 32Kbps*70 and 32Kbps*80 respectively. After the "update" button is executed, the real bandwidth will show up in RX fields. The limitation of the bandwidth control • The actual bandwidth should be less than the cable link speed. For 100Mbps link speed, the bandwidth setting should be less than 196 if the bandwidth is set to "high". For 10Mbps link speed, the bandwidth setting should be less than 20 if the bandwidth base is set to "high". • Setting the bandwidth to "0" means no bandwidth control, it will run at the full speed. The warning message will shows up if bandwidth setting is higher than maximum rate (100Mbps). 19

Example 3:
The RX bandwidth number of the port 5~ port 8 is set to 50, 60, 70, 80
respectively, and Speed base is set to “low”. The real bandwidth comes from the
formula of 32Kbps*50, 32Kbps*60, 32Kbps*70 and 32Kbps*80 respectively After the
“update” button is executed, the real bandwidth will show up in RX fields.
(d) High bandwidth for RX
Example 4:
The RX bandwidth number of the port 5~ port 8 is set to 50, 60, 70, 80
respectively, and Speed base is set to “high”. The real bandwidth comes from the
formula of 32Kbps*50, 32Kbps*60, 32Kbps*70 and 32Kbps*80 respectively. After the
“update” button is executed, the real bandwidth will show up in RX fields.
The limitation of the bandwidth control
•
The actual bandwidth should be less than the cable link speed. For 100Mbps link
speed, the bandwidth setting should be less
than 196 if the bandwidth is set to
“high”. For 10Mbps link speed, the bandwidth setting should be less than 20 if the
bandwidth base is set to “high”.
•
Setting the bandwidth to “0” means no bandwidth control,
it will run at the
full speed.
The warning message will shows up if bandwidth setting is higher than maximum rate
(100Mbps).
