By default, this simple policy is color blind, and color classes do not apply. A simple

outcomes: conform or violate.
Specify a policy action for packets that conform or violate to the policy:
a. Committed Rate. Enter the committed rate that is applied to conforming packets
by specifying a value in the range from 1 to 4294967295 Kbps.
b. 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.

• Send. Packets are forwarded unmodified. This is the default confirming 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

overrides any selection from the menu.
The DSCP value is defined as the high-order six bits of the Service Type octet
in the IP header.
