show policy-map interface
Traffic Shaping: Example
The following sample output from the show policy-map interface command (shown below) displays the
statistics for the serial 3/2 interface. Traffic shaping has been enabled on this interface, and an average
rate of 20 percent of the bandwidth has been specified.

Field Description
Service-policy output Name of the output service policy applied to the specified interface or VC.
Class-map Class of traffic being displayed. Output is displayed for each configured
class in the policy. The choice for implementing class matches (for
example, match-all or match-any) can also appear next to the traffic class.
packets, bytes Number of packets (also shown in bytes) identified as belonging to the
class of traffic being displayed.
offered rate Rate, in kbps, of packets coming in to the class.
Note If the packets are compressed over an outgoing interface, the
improved packet rate achieved by packet compression is not
reflected in the offered rate. Also, if the packets are classified
before they enter a combination of tunnels (for example, a generic
routing encapsulation (GRE) tunnel and an IP Security (IPSec)
tunnel), the offered rate does not include all the extra overhead
associated with tunnel encapsulation in general. Depending on the
configuration, the offered rate may include no overhead, may
include the overhead for only one tunnel encapsulation, or may
include the overhead for all tunnel encapsulations. In most of the
GRE and IPSec tunnel configurations, the offered rate includes the
overhead for GRE tunnel encapsulation only.
drop rate Rate, in kbps, at which packets are dropped from the class. The drop rate
is calculated by subtracting the number of successfully transmitted
packets from the offered rate.
