Queue Bandwidth Control Settings
This window is used to configure queue bandwidth control settings.
To view the following window, click QoS > Queue Bandwidth Control Settings:
Figure 5 - 3. Bandwidth Control window
The following parameters can be set or are displayed:
Parameter Description
From Port / To Port
Use the drop-down menus to select a range of ports to be configured.
From Queue / To Queue
Use the drop-down menu to select the queue range to use for this configuration.
Max Rate (64-1024000) Enter the maximum rate for the queue. For no limit select the No Limit option.
Click Apply to implement the changes.
Traffic Control
On a computer network, packets such as Multicast packets and Broadcast packets continually flood the network as normal
procedure. At times, this traffic may increase do to a malicious endstation on the network or a malfunctioning device, such as a
faulty network card. Thus, switch throughput problems will arise and consequently affect the overall performance of the switch
network. To help rectify this packet storm, the Switch will monitor and control the situation.
Packet storms are monitored to determine if too many packets are flooding the network based on threshold levels provided by the
user. Once a packet storm has been detected, the Switch will drop packets coming into the Switch until the storm has subsided.
This method can be utilized by selecting the Drop option of the Action parameter in the window below.
The Switch will also scan and monitor packets coming into the Switch by monitoring the Switch’s chip counter. This method is
only viable for Broadcast and Multicast storms because the chip only has counters for these two types of packets. Once a storm
has been detected (that is, once the packet threshold set below has been exceeded), the Switch will shut down the port to all
incoming traffic, with the exception of STP BPDU packets, for a time period specified using the Count Down parameter.
