Chapter 6 Policing Traffic
Configuring Traffic Policing
• The set-cos-inner-transmit police action sets only the inner CoS bits.
• The router supports the set-cos-inner-transmit policing action only on QinQ subinterfaces. If you
configure this policing action in a flat policy map or a 2-level hierarchical policy and attach the
policy to an interface that is not a QinQ subinterface, the router displays an error message. However,
if you configure the set-cos-inner--transmit action in a 3-level policy map and attach the policy to a
non-QinQ subinterface, no error message displays and the router appears to accept the policy.
Therefore, we recommend that you do not use the set-cos-inner-transmit policing action in a 3-level
policy map attached to non-QinQ subinterfaces.
• The router supports the set-clp-transmit and set frde-transmit police actions on the ingress for an
Any Transport over MPLS (AToM) Layer 2 VPN (L2VPN) configuration only.
• The router supports only the following combinations of dual actions on the AToM L2VPN ingress:
– set-clp-transmit and set-mpls-exp-imposition-transmit
– set-frde-transmit and set-mpls-exp-imposition-transmit
• The router does not perform extensive error checking to reject invalid combinations of dual actions.
If you provide unsupported combinations, the results may be unpredictable.
• On the PRE3 and PRE4, the router enters policy-map-class-police configuration mode after you
enter the police command, regardless of whether the command specifies a single action or dual
actions.
• On the PRE3 and PRE4, when specifying multiple actions, the router displays each action on a
separate line.
Configuring Traffic Policing
To configure traffic policing, perform any of the following configuration tasks:
• Configuring Single-Rate Traffic Policing Based on Bits per Second, page 6-28
• Configuring Percent-Based Policing, page 6-32
• Configuring Two-Rate Policing, page 6-35
• Marking Traffic Using Police Actions, page 6-36
• Configuring Dual Police Actions, page 6-37
