CoS Settings Menu
Given that there will always be points in the network where multiple traffic streams merge or
where network links will change speed and capacity, it is important to move traffic on the
basis of relative importance. Without CoS prioritization, less important traffic can consume
network bandwidth and slow down or halt the delivery of more important traffic. For example,
without CoS, most traffic received by the Gateway is forwarded with the same priority it had
upon entering the Gateway. In many cases, such traffic is ‘‘normal’’ priority and competes for
bandwidth with all other normal-priority traffic, regardless of its relative importance to your
requirements. CoS helps to keep the most important network traffic moving at an acceptable
speed, regardless of current bandwidth usage. This means you can manage available
bandwidth so that the switch transmits the most important traffic first.
The CoS Settings menu lets you configure a CoS priority of 0 through 7 for an outbound
packet. When the packet is then sent to a port, the CoS priority determines which outbound
queue the packet uses. After configuring CoS priority for outbound packets, use this menu to
map the classes of service to the Gateway’s four ports.
To access the CoS Settings menu, click
QOS
in the menu bar and then click the
CoS
submenu in the menu bar. Figure 32 shows an example of the menu.
Note:
The
COS
submenu is not available in the menu bar if
Enable QOS Module
is not checked in the QoS Settings menu (see page 62).
