DESCRIPTION
"This object identifies the queuing discipline that is

by this attribute. Queuing disciplines that differ from
those that are supported by this object are specified
by setting this attribute to other(1) and providing
the object identifier that represents the different
queuing paradigm in the qosIfQueueExtDiscipline object.
A value of fifo(2) indicates that the queue is serviced
on a first-in-first-out (FIFO) basis. This discipline is
generally employed when only a single queue is available
for a given interface.
A value of pq(3) indicates that the queue is serviced
using a priority queuing discipline. This technique is
used when several queues are available for a given
interface. Each queue is assigned a priority and queues
are serviced in order of priority. Higher priority queues
are completely drained before lower priority queues are
serviced.
A value of fq(4) indicates that the queue is serviced
using a fair queuing discipline. This technique is used
when several queues are available for a given interface.
Each queue is treated equally and is serviced in a
round-robin fashion.
A value of wfq(5) indicates that the queue is serviced
using a weighted fair queuing discipline. This technique is
used when several queues are available for a given interface.
Each queue is serviced based on queue weights which determine
the scheduling and frequency of queue servicing. Queues that
are assigned a greater weight are implicitly provided with
more bandwidth.
Note that the processing disciplines for all of the queues
in a given set must be considered when trying to establish
a processing profile for a given interface."

::= { qosIfQueueEntry 8 }
qosIfQueueServiceOrder OBJECT-TYPE
SYNTAX QosInterfaceQueueCount
STATUS current
DESCRIPTION
"This object is used to provide an additional level of
priority that is required for certain queuing disciplines
and when the different queues that comprise a queue set
are serviced using a mix of queuing disciplines. This
object can be used to specify, for example, the order in
which queues will be serviced when priority queuing is
used. It also supports the ability to describe the
servicing hierarchy when a hybrid queuing scheme, such
as priority queuing coupled with weighted fair queuing,
is used.
Queue service priority is assigned such that a lower
service order value indicates a higher priority. For
example, a priority queue with a value of 1 will be
serviced (i.e., drained) before another priority queue
with a service order value of 2.
Note that multiple queues that are logically associated,
based on the queuing discipline that is being employed,
will be assigned the same service order value. Under
this scenario, other parameters that are related to the
queuing discipline determine the order of queue servicing
(e.g., queue drain size is used for 'wfq').
For example, an interface that is associated with a queue
set supporting two priority queues and three queues that
are serviced using WFQ would be modeled as follows:
Q Index Q Discipline Q Drain Size Q Service Order
22 pq(1) - 1
23 pq(1) - 2
24 wfq(3) 500 3
25 wfq(3) 350 3
26 wfq(3) 150 3
The queue set presented in this example would service
all queued traffic in queue 22 first, followed by all of
the queued traffic in queue 23. Next the queued traffic
in queues 24 through 26 would be serviced in a round
robin fashion with queue 24 receiving 50% of the available
bandwidth, queue 25 receiving 35% of the available
bandwidth and queue 26 receiving 15% of the available
bandwidth. This example is presented for expository
purposes and has been simplified accordingly.
Note that, in this example, queues 24, 25 and 26 form a
queue cluster. Members of a queue cluster are all assigned
the same qosIfQueueServiceOrder as there are tightly
coupled. The qosIfQueueDrainSize attribute is used to
determine the additional processing characteristics of
the individual queues in a cluster."

DESCRIPTION
"An arbitrary integer index that uniquely identifies
the instance of the QoS Target class."
::= { qosTargetEntry 1 }
qosTargetAclId OBJECT-TYPE
SYNTAX PolicyInstanceId
STATUS current
DESCRIPTION
"This attribute identifies the ACL that is associated
with this target. It identifies (potentially many) ACL
class instances in a specific ACL Definition table
where ACLs, and their associated ACEs, are defined.
For example, instances in the qosIpAclDefinitionTable
are identified by setting the value of this object
equal to the qosIpAclDefinitionAclId of the instances
being targeted. This value, together with the value of
the corresponding qosTargetAclType attribute,
uniquely identifies one or more instances of a specific
ACL Definition class.
Attempting to specify an unknown ACL class instance will
result in an appropriate error indication being returned
to the entity that is attempting to install the conflicting
entry. For example, a 'priUnknown(2)' error indication is
returned to the policy server in this situation."
::= { qosTargetEntry 2 }
qosTargetAclType OBJECT-TYPE
SYNTAX OBJECT IDENTIFIER
STATUS current
DESCRIPTION
"The ACL Definition class that is being referenced by
this instance of the ACL Target class. This policy
class identifier, together with the corresponding
qosTargetAclId attribute, uniquely identifies
instances of a specific ACL Definition class.
The object identifier value of this attribute must
exist in the policyPrcSupportTable."
::= { qosTargetEntry 3 }
qosTargetInterfaceRoles OBJECT-TYPE
SYNTAX RoleCombination
STATUS current
DESCRIPTION
"The interfaces to which this ACL applies specified
in terms of a set of roles. The role combination
specified by this attribute must exist in the
qosInterfaceTypeTable prior to being association
with an instance of this class."
::= { qosTargetEntry 4 }
qosTargetInterfaceDirection OBJECT-TYPE
SYNTAX INTEGER {
in(1),
out(2)
}
STATUS current
DESCRIPTION
"The direction of packet flow at the interface in
question to which this ACL applies."
::= { qosTargetEntry 5 }
qosTargetOrder OBJECT-TYPE
SYNTAX Unsigned32
STATUS current
DESCRIPTION
"An integer that determines the precedence order of
this ACL in the list of ACLs applied to interfaces of
the specified role combination. An ACL with a given
precedence order is positioned in the list before one
with a higher-valued precedence order.
As an example, consider the following ACL Target association:
Index IfRoleCombo IfDirection AclId AclType Order
14 'eth1000+L2+L3' 'in' 8 '802' 1
15 'eth1000+L2+L3' 'in' 3 '802' 2
16 'eth1000+L2+L3' 'in' 12 'IP' 3
17 'eth1000+L2+L3' 'in' 6 'IP' 4
18 'eth1000+L2+L3' 'in' 21 'IP' 5
Five distinct ACL specifications, 3 from an IP ACL
Definition class and 2 from an IEEE 802 ACL Definition class,
form an Acl Target association (e.g., based on the specified
interface role combination and direction attributes) with a
prescribed order of evaluation. The AclType and AclId
attributes identify the ACL Definition instances in their
respective classes.
Precedence values within an association must be unique
otherwise instance installation will be prohibited and an
error value will be returned."
::= { qosTargetEntry 6 }
qosTargetMeter OBJECT-TYPE
SYNTAX PolicyInstanceId
STATUS current
DESCRIPTION
"This attribute identifies the meter that is associated
with this QoS Target instance. Meters are defined
in the qosMeterTable. The corresponding instance in
the qosMeter class (i.e., the class instance where
the qosMeterId is equal to the value of this object)
must exist prior to being associated with a Target
entry."
