Bandwidth Control

The bandwidth control settings are used to place a ceiling on the transmitting and receiving data rates for any selected port.
To view the following window, click QoS > Bandwidth Control:
The following parameters can be set or are displayed:
Parameter
From Port / To Port
Type
No Limit
Rate (64-1024000)
Effective RX
Effective TX
Click Apply to set the bandwidth control for the selected ports. Results of configured Bandwidth Settings are displayed in the
Bandwidth Control Table at the bottom of the window.

Description
Use the drop-down menus to select a range of ports to be configured.
This drop-down menu allows a selection between RX (receive), TX (transmit), and Both. This
setting will determine whether the bandwidth ceiling is applied to receiving, transmitting, or both
receiving and transmitting packets.
This drop-down menu allows the user to specify that the selected port will have no bandwidth
limit or not.
This field allows the input of the data rate that will be the limit for the selected port. The user
may choose a rate between 64 and 1024000 Kbits per second.
If a RADIUS server has assigned the RX bandwidth, then it will be the effective RX bandwidth.
The authentication with the RADIUS sever can be per port or per user. For per user
authentication, there may be multiple RX bandwidths assigned if there are multiple users
attached to this specific port. The final RX bandwidth will be the largest one among these
multiple RX bandwidths.
If a RADIUS server has assigned the TX bandwidth, then it will be the effective TX bandwidth.
The authentication with the RADIUS sever can be per port or per user. For per user
authentication, there may be multiple TX bandwidths assigned if there are multiple users
attached to this specific port. The final TX bandwidth will be the largest one among these
multiple TX bandwidths.
