qos Commands
The qos commands define and display Quality of Service (QoS) parameters. Use the
command to classify Layer 2, Layer 3, and Layer 4 traffic into the following priorities:
• control
•high
•medium
•low
By assigning priorities to network traffic, you can ensure that critical traffic will reach its
destination even if the exit ports for the traffic are experiencing greater than maximum
utilization. Use the qos set l2, qos set ip, and qos set ipx commands to assign priorities for
Layer-2, IP, and IPX traffic respectively.
Flows
For Layer 3 (IP and IPX) traffic, you can define “flows”, blueprints or templates of IP and
IPX packet headers.
• The IP fields are source IP address, destination IP address, UDP/TCP source port,
UDP/TCP destination port, TOS (Type of Service), transport protocol (TCP or UDP)
and a list of incoming interfaces.
• The IPX fields are source network, source node, destination network, destination node,
source port, destination port, and a list of incoming interfaces.
The flows specify the contents of these fields. If you do not enter a value for a field, a
wildcard value (all values acceptable) is assumed for the field.
