3. Configure the policy attributes:.
• 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.
4. If you select the Simple Policy attribute, you can configure the following fields:
• Color Mode. Color Aware mode requires the existence of one or more color classes
that are valid for use with this policy instance; otherwise, the color mode is color blind,
which is the default.
• Color Conform Class. A valid color class contains a single, non-excluded match
criterion for one of the following fields (provided the field does not conflict with the
classifier of the policy instance itself).
• Color Conform Mode. The match-criteria of the color Conform class.
• Committed Rate. The committed rate is specified in kilobits-per-second (Kbps) and is
an integer from 1–4294967295.
• Committed Burst Size. The committed burst size is specified in kilobytes (KB) and is
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.
• Mark CoS. These packets are marked by DiffServ with the specified CoS value
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
value before being presented to the system forwarding element. This selection
requires that the DSCP value field be set. If you select Other, enter a custom
value in the DSCP Value field that appears.
• Violate Action. Determines what happens to packets that are considered
non-conforming (above the police rate). Select one of the following actions:
