Smarter, More Secure, and More
Cost-effective 
The 8500 series is a managed switch that brings
enhanced security and Layer 2-4 intelligence to
networks. Many network administrators demand
easy to manage, cost-effective, intelligent switches
at the LAN edge, and the 8500 series switch
answers such demands, with the optimal balance
of features, performance, and value. More
intelligent than simple Layer 2 switches, the cost-
effective 8500 series offers advanced attack
detection and suppression capabilities for
increased security and advanced QoS to support
converged applications.
The sweet spot applications for such switches are:
• Traditional Enterprise LAN (wiring closet)
• Service-provisioned leased offices or MTUs
• Security-conscious Government and financial
institutions
• Cost/security-conscious educational institutions
Layer 2-4 Intelligence
The 8500 series packs a lot of features in one
rack unit. With advanced AlliedWare
TM
technology, the 8500 series switches allow
network administrators to configure the switch
to examine packet formats and content from
Layer 2, Layer 3, or Layer 4 (also known as the
MAC, IP and TCP/UDP layers). After these layer
parameters are defined and detected, the
switch can trigger network decisions such as
Access Control Lists (ACLs) for protection
against DoS attacks, establishing rate limits for
excessive bandwidth usage, and altering QoS to
support converged applications.
Securing the LAN Edge
With the heightened concern for Denial of
Services attacks, Allied Telesis is focusing on the
security features within its products. Assisted by the
Layer 2 through Layer 4 intelligence, network
administrators can deploy the 8500 series as a
complement to WAN firewalls and PC anti-virus
software to fortify networks against attacks.The
8500 switches are programmed to detect six well-
known DoS attacks, and coupled with security
features such as IEEE 802.1x (port-based network
access control) and Radius/ TACACS+, the 8500
series offers tiered security on each port.
Deploying tiered security within unsecured areas
of corporate offices—such as meeting rooms and
lounges—provides cost-effective protections at the
network layer.
Service Features for Revenue
Generation
Today’s global economic climate pushes network
administrators to focus on managing capital
spending. One way to keep costs low is to 
allocate resources efficiently. Allied Telesis  has
designed the 8500 series to allow smart
management of network resources with two
key features:
• Ingress and Egress rate-limiting to provision
bandwidth QoS support with IEEE 802.1p
and DSCP for priority traffic.
• The 8500 series also includes CoS to DSCP
remarking, allowing Layer 2 QoS priorities to
be preserved over the WAN (typically a Layer
3 feature).
The 8500 series can be pre-configured to
control bandwidth-wasting traffic—such as music
streaming to the desktops—by dynamically
lowering the priority and limiting bandwidths to a
mere trickle without completely blocking it.The
same features can benefit metro providers as well,
allowing them to offer bandwidth provisioning and
QoS priority as premium service to customers.
