Attaching a Traffic Policy to a PVC
Use the service-policy interface configuration command to attach a traffic policy to a VC and to specify
the direction in which the policy should be applied (either on packets coming into the interface or packets
leaving the interface).
Use the no form of the command to detach a traffic policy from a VC. The service-policy command
syntax is as follows:
service-policy {input | output} policy-map-name
no service-policy {input | output} policy-map-name

Software Configuration of ATM ISE Line Cards for Cisco 12000 Series Routers
Purpose
Specifies the minimum and maximum cell thresholds and,
optionally, the mark-probability denominator for the precedence
value.
Use either the random-detect dscp-based command with
Note
the random-detect dscp command or use the
random-detect precedence command alone. Do not use the
random-detect precedence command with either of the
DSCP commands.
Specifies the IP DSCP of packets within a traffic class. The IP DSCP
value can be any value between 0 and 63.
Sets the ATM cell loss priority bit to 1.
Specifies the IP precedence of packets within a traffic class. The IP
precedence value can be any value between 0 and 7.
Designates the value to which the MPLS experimental bits are set if
the packets match the specified policy map.
Specifies a QoS group value to associate with the packet. The QoS
group value can be any value between 0 and 99.
