The policy name, policy type, and member class name are stated in the Class Information
section at the top of the page. These fields are nonconfigurable on this page.
10. From the Assign Queue menu, select the queue to which packets of this policy class must
be assigned.
This is a value in the range from 0 to 7.
11. Configure the policy attributes:
• Drop. Select this radio button to require each inbound packet to be dropped.
• Mark VLAN CoS. Select this radio button to specify the VLAN priority, which you must
select from the menu. The VLAN priority is expressed as an integer value in the range
from 0 to 7.
• Mark IP DSCP. Select this radio button to require packets to be marked with an IP
DSCP keyword code, which you must select from the menu. If you select Other from
the menu, you can enter an IP DSCP value from 0 to 63. The DSCP value is defined
as the high-order 6 bits of the Service Type octet in the IP header.
• 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. The default color mode is Color Blind. Color classes do not apply.
• 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 an integer from 3000 to 19173960. The committed burst size is
the maximum amount of traffic that is allowed in one burst (in bytes).
Note: The switch uses the token bucket algorithm, in which the committed
rate is the rate at which the bucket is filled, and the committed burst
size is the size of the bucket. This means that the committed burst size
is the maximum size of a burst that the switch can send.
13. If you select the Simple Policy radio button, you can 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 conforming action and
the default violating action.
• Drop. Packets are dropped. This action can apply to a conforming action and to a
violating action.
