Bandwidth Control
The bandwidth control settings are used to place a ceiling on the transmitting and receiving data rates for any
selected port.
Bandwidth Control Settings
The Effective RX/TX Rate refers to the actual bandwidth of the switch port, if it does not match the configured rate.
This usually means that the bandwidth has been assigned by a higher priority resource, such as a RADIUS server.
To view the following window, click
QoS > Bandwidth Control > Bandwidth Control Settings
, as show below:
Figure 9-4 Bandwidth Control Settings window
The fields that can be configured or displayed are described below:
Parameter
Description
From Port / To Port
Use the drop-down menu to select the port range to use for this configuration.
Type
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.
No Limit
This drop-down menu allows the user to specify that the selected port will have no
bandwidth limit or not.
NOTE:
If the configured number is larger than the port speed, it means no bandwidth
limit.
Rate (64-1024000)
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.
Effective RX
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.
