Certified 1-minute plug-andplay for IP Phones
Plug-and-play means that as soon as
an IP Phone is plugged into an Avaya
Ethernet Switch, the IP Phone is
automatically recognized and
configured. This feature can
dramatically simplify the roll out of IP
Phones and simplify ongoing adds,
moves and changes; empowering
employees to move their own phones
without the assistance of an outside
contractor. To enable this plug-and-
play capability, Avaya offers IEEE
802.1AB Link Layer Discovery
Protocol and LLDP-Media Endpoint
Discovery (LLDP-MED) as well as the
Avaya Auto Discovery and Auto
Configuration (ADAC) feature.
With LLDP enabled, the ERS 3500
learns the identification of
neighboring devices and provides
these details to the network
management system. This enables the
system to have the most up-to-date
physical view of the network. In
addition, ERS 3500 can dynamically
apply voice VLANs and QoS to both
the IP Phone and the attached Edge
Switch port. When the IP Phone is
moved to another location, the
configuration is automatically
updated. QoS is also automatically
provisioned on the ERS 3500 uplink
ensuring voice is given top priority
into the Core. With one of the most
comprehensive implementations of
LLDP in the industry, Avaya offers
enhancements for standards based
provisioning of Avaya IP Phones via
integrated and customizable TLV
support.
and requires little to no formal
training for individuals with
networking backgrounds.
• For customers who are looking for a
simple Graphical User Interface
(GUI) for management and
provisioning, Avaya’s Enterprise
Device Manager (EDM) is an
embedded web-based element
management and configuration tool
that enables set-up, configuration
and monitoring of a single device
using either HTTP or HTTPS (Secure
Web). The on-box embedded
version of EDM is available at no
extra charge with every switch and
can be accessed by a standard web
browser. There is also an off-box
version available as a free
downloadable software plug-in that
can be installed on Avaya’s
Configuration and Orchestration
Manager (COM) application.
The Avaya ERS 3500 supports secure
management via IPv4 or IPv6 through
features such as Secure Shell
(SSHv1/2), Secure Sockets Layer
(SSL), Simple Network Management
Protocol (SNMPv1,2,3), IP Manager
Lists, and administrative
authentication via RADIUS or
TACACS+ when connecting to the
switch or stack.
Convergence-ready
for Unified
Communications,
High-Definition Video
and more
For businesses looking to consolidate
all forms of communication – voice,
video and data – on a single
infrastructure, the Avaya ERS 3500
Series delivers functionality that
simplifies convergence of these
technologies.
These features not only save network
operators time, they can virtually
eliminate the likelihood of a
provisioning error during a large IP
Phone deployment. Third-party
testing conducted by Miercom1
validated that when IP Phones were
plugged into an Avaya Ethernet
Switch, they were operational in just
over 1 minute.
Intuitive Management
ERS 3500 Series offers flexible
options for managing,
troubleshooting and operating your
devices.
• For customers more comfortable
using the Command Line Interface
(CLI), the ERS 3500 offers an
industry-aligned CLI that is intuitive

3500 devices, the Avaya
Configuration and Orchestration
Manager (COM) application,
simplifies multi-element
configuration via wizards and
templates – increasing consistency
and reducing the chances of error
during configuration changes. COM
also provides network discovery,
device backup, bulk configuration
management and audits of
configuration changes.
• SNMP-based management (SNMP
v1, v2 and v3) provides an
alternative standards-based
management approach as well as an
interface for Configuration and
Orchestration Manager.
Support for IEEE 802.3at PoE+
to power your Converged
Device
Through support for IEEE 802.3at
PoE+ which delivers up to 32 Watts of
power per port to end-devices, ERS
3500s are able to power IP Phones,
Wireless LAN Access Points,
networked high-definition CCTV
cameras and other devices. This
eliminates the need for separate
power supplies for each unit, enabling
reduced cabling and management
costs for adds, moves, or changes.
The higher power budget delivered
by the PoE+ standard ensures that
customers have the added flexibility
of converging video surveillance
traffic over the network, since pan, tilt
avaya.com | 3
and zoom cameras are one of the end
devices that require the additional
power provided by PoE+. It also
ensures investment protection for
future end points, such as new
Wireless LAN Access Points (3x3
802.11n Access Points and emerging
802.11ac Access Points) as well as
next-generation video phones.
The 24-port and 48-port PoE+
enabled products (ERS 3526T-PWR+,
ERS 3550T-PWR+, 3524GT-PWR+
and ERS 3549GTS-PWR+) support a
maximum power budget of 370
Watts. And the 10-port Gigabit
Ethernet model (ERS 3510-PWR+)
supports a maximum power budget
of 170 Watts – dramatically higher
than competitive switches in its
class – enabling it to deliver a
concurrent average of 20 Watts of
power to each of the eight PoE+
enabled access ports.
Comprehensive QoS
capabilities
The ERS 3500 series delivers
unsurpassed control for networks
supporting a wide range of different
application types. The ERS 3500
classifies, prioritizes and marks LAN
IP traffic using up to four hardware
queues on every port – including the
rear SFP ports.
Classification can be based on MAC
address, IP ToS/DSCP marking, IP
source/destination address or
subnets, TCP/UDP source/destination
port/port range, IEEE 802.1p user
priority bits, ingress source port, IP
Protocol ID (e.g., TCP, UDP, IGMP),
EtherType (e.g., IP, IPX) or the IEEE
802.1Q VLAN ID. Comprehensive

traffic policing and traffic shaping are
also supported.
Intelligent stacking
solution delivering
scalability, flexibility,
resilience and
performance
No one knows
stacking like
Avaya . We
introduced our
first Stackable
Chassis
product in 1998 and have been
perfecting the technology ever since.
We were the first and only vendor to
break the Terabit boundary with our
ERS 5600 Series products and we
have differentiated ourselves in the
industry by ensuring that our
Stackable Chassis perform like a
traditional modular chassis
implementation. We offer genuine
chassis-like features including true
pay-as-you-grow scaling and in
service maintenance and restoration.
From a management perspective, our
Stackable Chassis looks like a single
network entity – utilizing only a single
IP address.
Up to eight ERS 3500 units can be
stacked – combining 24 or 48-port
models – to deliver up to 80Gbps
stacking throughput and up to 384 x
10/100/1000 user ports. Stacking is
supported on ERS 3526T/3526T-
PWR+, ERS 3550T/3550T-PWR+, ERS
3524GT/3524GT-PWR+ and ERS
3549 GTS/3549 GTS-PWR+ models.
High performance architecture
with true pay-as-you grow
scaling
Our Stackable Chassis products
combine non-blocking internal
switching fabrics with high-speed
virtual backplane architecture for a
4 | avaya.com
high performance solution that scales
proportionally as new switches are
added. The ERS 3500 series scales to
a maximum of 80Gbps of virtual
backplane throughput by simply
cabling up 8 units together. Avaya’s
Stackable Chassis architecture
simplifies stack management.
Customers do not have to worry
about different software versions on
different products, since all ERS 3500
units run the same software image.
The software image is loaded onto
the base unit of the stack which then
loads the image to all the other
Switches in the stack. As new units
are added to the stack, the ERS 3500
automates the software image and
configuration download process.
Third party testing1 has validated that
new ERS 3500 units can become
operational in just over 2 minutes of
being cabled into the stack.
To ensure wire-speed performance,
our Stackable Chassis architecture is
based on a shortest-path forwarding
algorithm for optimal data flow
across the stack. Unlike competitive
solutions that use unwieldy
logical ring or token technology,
Avaya allows traffic to flow upstream
and downstream simultaneously from
every Switch connected to the virtual
backplane, optimizing performance,
resiliency, and resource utilization.
Avaya has an additional advantage in
that Quality-of-Service settings are
honored as traffic passes over the
stacking connections – providing
applications with optimal
performance, and a positive user
experience.
All ERS 3500 24 and 48-port models
come with two in-built Stackable
Chassis interfaces for simple, cost-
effective and efficient connectivity.
Unlike comparative offerings which
daisy chain low-speed interfaces,
this design frees uplink ports for
dedicated connectivity to the
backbone. In addition to the stacking
cables, a return cable is also used to
provide full virtual chassis resiliency
and to protect against any stack port,
Switch unit or cable failures.
Unlike competitive solutions which
charge large premiums for stacking,
the ERS 3500 offers the ability for
customers to utilize its Stackable
Chassis architecture without incurring
any licensing or hardware costs.
In-service maintenance and
restoration
Virtual hot swap, a critical
serviceability and operability
capability, helps ensure that failure in
any stacked unit is quickly and easily
rectified. Pioneered in modular
switches, virtual hot swap is available
in Avaya Stackable Chassis solutions
where, without complex engineering,
it enables immediate like-for-like unit
replacement with no impact on other
functionality and traffic, empowering
operators to deploy our solutions just
as they would a chassis. If a failure
occurs, neighboring switches
automatically wrap their fabric
connections to help ensure that other
Switches in the stack are not
impacted. The failed unit is simply
disconnected from the fabric and,
without pre-staging of software or
configuration, a like unit is inserted,
cabled, and powered-up. The
Automatic Unit Replacement (AUR)
process self-manages the software
and configuration downloads to the
new Switch then brings it online,
without the need for an engineer to
manage the process.
Further complementing the Avaya
ERS 3500 solution, Avaya supports
standards-based 802.3ad Link
Aggregation as well as its own Multi-
Link Trunking technology that allows
grouping of ports to form high-speed
trunks/aggregations. These bundles
or groups of ports can be distributed
across different units in the same
stack, delivering higher levels of
resilience in case of link or switch
failure to help ensure that traffic gets
to its destination.
Stack health-check monitoring, a real-
time, at-a-glance view of stack
operational status and health,
further enhances operational and
management simplicity.
Centralized Management
From a management perspective, an
ERS 3500 Stackable Chassis solution
appears as a single networking
entity – utilizing only a single IP
Address. This can significantly reduce
the number of Switches to be
managed within the network as a
stack of up to 8 Switches can be
managed just as easily as a single
device.
