• Simple Policy. Select this radio button to define the traffic policing style for the class.
A simple policy uses a single data rate and burst size, resulting in one of two
outcomes: conform or violate. You must define the policy as described in the next
step.
12. If you select the Simple Policy radio button, you can specify the traffic policing style for the
class:
• Color Mode. From the menu, select one of the following options:
- Color Blind. This is the default selection. Color classes do not apply.
- Color Aware. Requires you to select a color class that is valid for use with this
policy instance. After you select Color Aware from the Color Mode menu, the
Color Conform Class menu displays. From this menu you must select a color
class that you already created (see
Configure a DiffServ Class on page 176) and
selected as a member class for this policy instance (see Step 7).
Note: A valid color class contains a single, non-excluded match criterion for
the CoS, IP DSCP, or IP Precedence option. The configured option
must not conflict with the classifier of the policy instance itself.
• Committed Rate. Enter the committed rate that is applied to conforming packets by
specifying a value in the range from 1 to 4294967295 Kbps.
• Committed Burst Size. Enter the committed burst size that is applied to conforming
packets by specifying a value in the range from 1 to 128 Kbps.
13. Select the conforming and violating actions.
The Conform Action section and Violate Action section list the actions to be taken on
conforming packets according to the policing metrics. By default, both conforming
packets and violating packets are sent.
In both the Conform Action section and the Violate Action section, select one of the
following actions:
• Send. Packets are forwarded unmodified. This is the default confirming action and the
default violating action.
• Drop. Packets are dropped.
• Mark CoS. Packets are marked by DiffServ with the specified CoS value before being
forwarded. This selection requires that the Mark CoS field is set. You must select a
CoS value from 0 to 7 from the menu.
• Mark IP Precedence. These packets are marked by DiffServ with the specified IP
Precedence value before being forwarded. This selection requires that the Mark IP
Precedence field is set. You must select an IP precedence value from 0 to 7 from the
menu.
• Mark IP DSCP. Packets are marked by DiffServ with the specified DSCP value before
being forwarded. This selection requires that the DSCP field is set. You must select a
DSCP code from the menu. The menu includes Other as a selection, which lets you
enter an IP DSCP value from 0 to 63. The DSCP value is defined as the high-order six
bits of the Service Type octet in the IP header.
