Policy Attribute Selector
D-Link DWC-1000 User Manual
The menu lists all the attributes supported for this type of policy, from which one can be
selected. To configure the attributes, select an attribute from the list. The screen changes
to the attribute configuration page for that attribute. After you configure the attribute,
click Save to apply the criteria to the class and return to the Policy Class Definition page.
The attributes and configurable fields are as follows:
• Assign Queue: Assigns the packets of this policy-class to a queue. Enter an integer
from 0-7 in the Queue Id Value field.
• Drop Packets: Select this field to drop packets for this policy-class. There are no
fields to configure. Once you select Drop, click Save, and the attribute is added to
the policy.
• 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 (the only tag in a single tagged packet or the first or outer
802.1q tag of a double VLAN tagged packet). If the packet does not already contain
this header, one is inserted. The CoS value is an integer from 0 to 7.
• Mark IP DSCP: Use this attribute to mark all packets for the associated traffic stream
with IP DSCP value you choose from the menu.
• 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.
• Police Simple: Use this attribute to establish the traffic policing style for the specified
class. The simple form of the police command uses a single data rate and burst
size, resulting in two outcomes: conform and violate. The conforming data rate is
specified in kilobits-per-second (Kbps) and is an integer from 1 to 4294967295. The
conforming burst size is specified in kilobytes (KB) and is an integer from 1 to 128.
The Police Simple attribute configuration page has the following configurable fields:
• Color Mode: Color Aware mode requires the existence of one or more color classes
that are valid for use with this policy instance. 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):
- IP DSCP
- IP Precedence
• Conform Action Selector: It determines what happens to packets that are
considered conforming. Select one of the following actions:
- Send: (default) These packets are presented unmodified by DiffServ to the
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 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.
- 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.
• Violate Action: It determines what happens to the packets that are considered
non-conforming. The available actions are: Drop, Mark CoS, Mark IP DSCP, Mark IP
Precedence and Send.
