Configuring port-based traffic policing

Use an ingress or egress policy map that has been created and populated with policing parameters.

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

Enter interface configuration mode

 device(config)# interface ethernet 2/2

Attach an input or output policy map.
```
 device(conf-if-eth-2/2)# service-policy out policy_2 
```
For rate limiting ingress traffic just replace the out keyword with in and use an ingress policy map.
Return to privileged EXEC mode.
```
 device(conf-if-eth-2/2)# end 
```

Verify the configuration.

 device# show policy-map interface ethernet 2/2 out

Egress Direction :
 Policy-Map policy_2
    Class default
      Police cir 4000000 cbs 50000 eir 800000 ebs 400000
        Stats:
          Operational cir:4006912 cbs:50000 eir:0 ebs:400000
          Conform Byte:0 Exceed Byte:0 Violate Byte:0

Note

Egress policer is not supported on the SLX 9150/Extreme 8520 device. The police command affects only the CIR.

Port-based traffic policing configuration example

 device# configure terminal
device(config)# interface ethernet 2/2
device(conf-if-eth-2/2)# service-policy out policy_2
device(conf-if-eth-2/2)# end
device# show policy-map interface ethernet 2/2 out
