Multi-Action Policing
When CB Policing re-marks packets instead of discarding them, the design might call for marking more than one field in a packet. For instance, when transmitting into a Frame Relay cloud, it might be useful to mark both DSCP and FR DE when a packet violates the contract. Marking multiple fields in the same packet with CB Policing is called multi-action policing.
The police command uses a slightly different syntax to implement multi-action policing. By omitting the actions from the command, the police command places the user into a policing subconfiguration mode in which the actions can be added via separate commands (the conformaction, exceed-action, and violate-action commands). To configure multiple actions, one of these three action commands would be used more than once, as shown in Example 16-10, which marks
DSCP 0 and sets FR DE for packets that violate the traffic contract.
