Abstract
The purpose of this Technical Configuration Guide (TCG) is to provide configuration examples on various
Avaya voice and data products (Ethernet Routing Switch 4500, 5000, Avaya BCM 50, 450, Avaya
CS1000, Avaya CS 2100 and Avaya SRG 50) that support Avaya Automatic QoS. Avaya Automatic QoS
is a set of capabilities that dramatically simplifies configuration of Quality of Service (QoS) in a network to
ensure proper prioritization and forwarding of different traffic types.

Please note that Avaya Automatic QoS configuration on an Avaya switch or Avaya voice
application is referred to as Avaya on Avaya configuration in the initial release.
1. Overview: Avaya Automatic QoS
Avaya Automatic QoS provides application traffic prioritization allowing for the ability to identify and
prioritize Avaya application traffic on both an Avaya only or Avaya edge and third party core data
infrastructure to provide application aware networking. Avaya application traffic is defined as IP
Telephony and Multimedia applications. By identifying Avaya application traffic, Avaya Automatic QoS
transparently provides appropriate traffic prioritization handling and in turn improves application
performance particularly in times of network congestion. Avaya Automatic QoS is applied end-to-end from
the application traffic to the Avaya or third party data infrastructure without the need to configure
individual application filters and QoS components across a variety of platforms. Simply enable/disable the
appropriate Avaya Automatic QoS mode and all underlying QoS configurations to identify Avaya
application traffic are automatically configured. Well known Avaya application traffic that is automatically
identified via DSCP values will be given preferential treatment and will be handled by the appropriate
egress queue on the Ethernet switching infrastructure.
As shown in the diagram below, dynamic prioritization is provided by enabling Avaya Automatic QoS on
the ERS 4500 or ERS 5000 edge access switch and on the Avaya CS 1000, Avaya CS 2100, Avaya
BCM, and/or Avaya SRG call servers. In regards to the edge switch, the ERS 4500 or ERS 5000 support
dynamic prioritization for either tagged or untagged IP telephony traffic. The only other configuration
required on the edge switch is setting the uplink port members attached to the core/distribution layer as
trusted port members. In the core, all that is required is enabling the port members as QoS trusted.
