Entuity Quality of Service Module
The Entuity Quality of Service (QoS) module places QoS details within the context of network device availability and
performance, thus reducing QoS administration and improving troubleshooting and mean time to repair. The module also
provides a detailed inventory of your QoS configuration as well as realtime monitoring of the performance of each interface.
Highlights
Automatically discovers
critical configuration details
and presents them in the
context of overall network
performance
Provides control over
resources, with visibility
into the current and historic
utilization of resources, such
as bandwidth and devices
Managing QoS Using Entuity
Entuity QoS is a full SNMP integration using
QoS configuration information and its associated
performance and availability statistics are accessible
through:
the Cisco-Class-Based-QOS-MIB. Entuity
QoS discovers interfaces that support the
MIB, collecting configuration, availability and
performance data.
Entuity understands the possibly recursive
structure of QoS implementations where, for
example, a policy can include a class map which
in turn can include policy and class maps. Entuity
presents these interrelations under the relevant
policy map on the device’s port.
WebUI, where the latest polled configuration
and statistical data is presented, but you can
also use graph and change history tools to view
trends over the past 28 days
Reporting tools, for example a new QoS Port
report and custom reports using drag and drop
Report Builder
Enables efficiency of network
resource usage through
greater visibility into what
your network is used for
Allows delivery of services
through close monitoring of
the traffic flows that are most
important to your business

Traffic Identification through
Access Groups
Through access lists devices can classify packets
by physical port, source or destination IP address,
application port, IP Protocol type, MAC address and
so on.
Entuity displays access lists:
Ordering them in the same sequence as they
are configured, and therefore the same order as
they are applied
Pre-and post-policy traffic performance statistics
Traffic Management through
Class Maps
Classification and admission control are typically
performed at the network edge, ensuring traffic
conforms to the internal network policy. Packets
can be marked with special flags (colors), which
are used inside the network for QoS management.
For each class, Entuity displays traffic management
configuration and pre- and post- policy performance
statistics.
Using Entuity’s Business Views you can monitor
the traffic policing configuration on interfaces at the
edge of your network. Typically conforming traffic
is transmitted and traffic that exceeds is sent with a
decreased priority or dropped.
Through Entuity providing detailed QoS
configuration information and extensive statistics on
port performance, you can amend the configuration
to meet changing network requirements.
Managing Congestion through
Queues
Queue management is an important congestion
tool, for example for avoiding tail drops, where
high priority packets are dropped before they are
added to a router’s queue, and so identified.
Entuity details both queue configuration and
current performance, for example current queue
depth and number of discarded packets. You
can check queues associated with high priority
classes are assigned greater resources, reducing
the probability of losing high priority packets, than
those associated with lower priority classes.
Managing Policy Maps
Policy maps are applied to the interface as service
policies. Each interface has a maximum of two
service policies, one for inbound traffic, one for
outbound. Entuity details the classes associated with
the policy map.
QoS Traffic Policing
Traffic policing allows you to control the maximum
rate of traffic sent or received on an interface, and
to partition a network into multiple priority levels or
Classes of Service (CoS).

Managing Congestion
Avoidance
Cisco IOS QoS allows Class-Based Weighted Fair
Queuing Configuration (CBWFQ) with Weighted
Random Early Detection (WRED). Entuity
allows you to appropriately modify congestion
management through displaying class configuration
and its performance, for example:
Whether explicit congestion notification is
enabled for the class, precedence thresholds
for the service profiles
Performance statistics such as number of
transmited packets, tail dropped packets,
random packets.

Managing Packet Marking
Managing QoS Traffic Shaping
Packet marking allows partition of your network
Traffic shaping attempts to control the
into multiple priority levels or CoS, by either:
Marking packets by setting either the IP
precedence bits or IP differentiated services
code point (DSCP) in the Type of Service (ToS)
byte. Packets are classified by this value and
receive appropriate differentiated QoS service.
Associating a QoS group value with a packet.
This allows users to associate a group ID with
a packet, which can be used to classify packets
into QoS groups based on prefix, autonomous
system, and community string.
Entuity QoS identif ies the packet marking
method applied on the parent class map and
displays its conf iguration details.

volume of traffic sent into a network, and
the rate at which the traffic is sent. Entuity
QoS can show the separated traffic flows
and the individual shaping of each, indicating
where the current configuration can be
improved to better manage the current
traffic.
QoS Warning Events
Warning events can be generated on top
of existing threshold information configured
via the Threshold Settings dialog in the
client. These events cover QoS class
characteristics of bit rate, bit drop rate
and packet drop rate resulting from buffer
shor tages. The four th event allows high
queue drop bit rates to be flagged as events
as well.
