The AT-8800 series Intelligent Workgroup
Switches deliver high performance switching in
a compact 1RU form factor. Available with
either 24 or 48 10/100 Fast Ethernet ports,
both models offer full wirespeed switching and
IP routing across all layers, with two optional
gigabit Ethernet uplink ports and redundant
power supply.The AT-8800 Intelligent
Workgroup Switches build upon proven Rapier
and Rapier i switch technology.
Why is this Switch Right for
my Network?
The features on the AT-8800 Intelligent
Workgroup Switches make it the perfect choice
for your workgroup applications, incorporating
ease of management, high bandwidth, proven
security and traffic prioritization in a slimline
1RU chassis.The AT-8800 Intelligent Workgroup
Switches are ideal for environments like
enterprise and educational institutions
demanding reliable, high bandwidth Ethernet for
services such as web conferencing and live
video streaming. Prioritization of data streams
with QoS ensures that mission critical traffic will
enter the fastest queue. Combining this with
the stateful inspection firewall, your network will
remain safe and secure. Configure and manage
these functions with our intuitive GUI and you
have the ideal switch for your enterprise or
educational institution.
AT-8800 Intelligent Workgroup
Switch Features
AT-8800 Intelligent Workgroup Switches have
asymmetric bidirectional bandwidth limiting, per
port or per QoS traffic class. Bandwidth
limiting lets you define throughput levels on an
individual client basis. For example, you may
want to assign more bandwidth to a campus
library than student accommodation. Delivering
an industry-leading implementation of this
feature, AT-8800 Intelligent Workgroup Switches
provide the finest bandwidth granulation
available in Layer 3 products.
The Quality of Service (QoS) feature allows
you to prioritize traffic according to its
importance.You can be assured of reliable
performance during peak usage periods, and
continuous transmission of streaming media.
The 802.1x protocol enhances the already
robust security on the switch. Authentication
can be required for external devices wishing to
access services behind a port before any
Ethernet packets from the device are permitted
to pass through it. In addition, 802.1x provides
the ability to offer restricted services via the
LAN for use by specific devices, such as a
laptop connecting to a server on the LAN.
All Allied Telesis' Layer 3 switches come with
the feature-rich AlliedWare operating system,
and you can choose to add more. For advanced
networking applications on AT-8800 Intelligent
Workgroup Switches, Allied Telesis offers three
optional feature licences: Full Layer 3 upgrade,
Advanced Layer 3 upgrade, and Security
upgrade. The Full Layer 3 upgrade enables a set
of additional routing protocols and features
such as IPX, DVMRP, PIM-DM/SM and RSVP.
The Advanced Layer 3 upgrade enables a set of
more specialized features comprising IPv6,
BGP4, and Load Balancer.The Security upgrade
offers a Stateful Inspection Firewall as well as
both SMTP and HTTP application gateways.

AT-8800 SERIES | Intelligent Workgroup Switches
These options allow you to tailor your chosen
Intelligent Workgroup Switch to suit your
requirements.
The base software release on the AT-8800
Intelligent Workgroup Switches offers you a
suite of advanced switching features including:
IEEE 802.1Q VLAN Tagging
IGMPv2
802.1p Traffic Prioritization of packets at
Layer 3 and Layer 4
Broadcast and multicast traffic limiting.
Stacking
Stacking provides Web and CLI based
management of up to 9 switches with the same
effort as for one switch.The Allied Telesis
solution uses open standards interfaces as
stacking links so that many switches can be
stacked across different sites, which is not
possible using the proprietary stacking cable
solutions. Also the use of open standards
interfaces avoids the use of expensive
specialized hardware with limited topologies.
New and Progressive Features
The AT-8800 series brings exciting new features
to the already comprehensive AlliedWare
software suite. This ensures a breadth of
functionality that is exactly right for a wide
variety of applications. New software features
include 802.1x, DHCPv6,TACACS+, SNMPv3.
