NOTE: Traffic Control cannot be implemented on
ports that are set for Link Aggregation.
NOTE: Ports that are in the rest mode will be
seen as Discarding in Spanning Tree windows
and implementations though these ports will still
be forwarding BPDUs to the Switch’s CPU.
NOTE: Ports that are in rest mode will be seen as
link down in all windows and screens until it
enters the auto-recovery mode or the user
recovers these ports by configuring the port state.
QoS > Bandwidth Control
The Bandwidth Control page allows network managers to define the bandwidth settings for a specified port’s
transmitting and receiving data rates.
Figure 4.112 – QoS > Bandwidth Control
From Port / To Port: A consecutive group of ports may be configured starting with the selected port.
Type: This drop-down menu allows you to select 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 you to specify that the selected port will have no bandwidth limit.
Enabled disables the limit.
Rate (63-1024000): This field allows you to enter the data rate, in Kbits per second, will be the limit for the
selected port. The value is between 63 and 1024000.
Click Apply to set the bandwidth control for the selected ports.
NOTE: The TX rate for Gigabit ports can only be
configured in multiples of 1850kbps. If any other
value is used, the system automatically rounds it
down to the lower multiple of 1850.
QoS > CoS Scheduling Mechanism
The CoS Scheduling Mechanism page allows user to select between a WRR and a Strict mechanism for
emptying the priority classes.
