Applying the QoS policing rate to an interface

A policy map has been configured.

Enter global configuration mode.
```
device# configure terminal
```

Access interface configuration mode.

device(config-policymap-class)# interface ethernet 1/49

Bind the ingress policy map policy map to the interface.
```
device(conf-if-eth-1/49)# service-policy in policy_1
```
Return to privileged EXEC mode.
```
device(conf-if-eth-1/49)# end
```

Verify the configuration.

device# show policy-map

Number of policy maps : 2
...
Policy-Map policy_1
  Bound To: Et 1/49(in)

Save the running-config file to the startup-config file.
```
device# copy running-config startup-config
```
