• Drop. Select this option to drop packets for this policy-class.
• Mark CoS. Enter the specified Class of Service queue number to mark all packets for 
the associated traffic stream with the specified class of service value in the priority 
field of the 802.1p header. If the packet does not already contain this header, one is 
inserted. The CoS value is an integer from 0–7.
• Mark IP Precedence. Use this attribute to mark all packets for the associated traffic 
stream with the IP Precedence value you enter in the IP Precedence Value field.
• Mark IP DSCP. Use this attribute to mark all packets for the associated traffic stream 
with IP DSCP value you choose from the menu. If you select Other, enter a custom 
value in the DSCP Value field that appears.
• Simple Policy. Use this attribute to establish the traffic policing style for the specified 
class. The simple form of the policy command uses a single data rate and burst size, 
resulting in two outcomes: confirm and violate.

an integer from 1–128.
• Conform Action. Determines what happens to packets that are considered 
conforming (below the police rate). Select one of the following actions:
• Send. (default) These packets are presented unmodified by DiffServ to the 
system forwarding element.
• Drop. These packets are immediately dropped.

before being presented to the system forwarding element. This selection requires 
that the Mark CoS value field be set. 
• Mark IP Precedence. These packets are marked by DiffServ with the specified IP 
Precedence value before being presented to the system forwarding element. This 
selection requires that the Mark IP Precedence value field be set.
• Mark IP DSCP. These packets are marked by DiffServ with the specified DSCP
