2. Create a traffic behavior
and enter traffic
behavior view.
traffic behavior
behavior-name
The specified traffic behavior name cannot be
the name of any system-defined behavior.
3. Configure a WRED drop
action.
wred [ dscp |
ip-precedence ]
• dscp—Uses the DSCP value for calculating
the drop probability for a packet.
• ip-precedence—Uses the IP precedence
value for calculating the drop probability for
a packet. This keyword is used by default.
You can configure the wred [ dscp | ip-precedence ] command only after configuring the queue af
command or the queue wfq command.
When a QoS policy including the WRED traffic behavior is applied to an interface, the previous
interface-level WRED configuration gets invalid.
Defining a QoS policy

2. Enter interface view, port
group view, or PVC view.
• Enter interface view:
interface interface-type
interface-number
• Enter port group view:

b. pvc vpi/vci
Settings in interface view take
effect on the current interface.
Settings in port group view take
effect on all ports in the port group.
Settings in PVC view take effect on
the current PVC.
