8500 Series
Managed Fast Ethernet Switches
AT-8516F/SC-xx
16 port 100FX (SC) Layer 2+ switch
with 2 expansion bays
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 costeffective 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:
‫ ۼۼ‬Traditional Enterprise LAN (wiring
closet)
‫ ۼۼ‬Service-provisioned leased offices
or MTUs
‫ ۼۼ‬Security-conscious Government
and financial institutions
‫ ۼۼ‬Cost/security-conscious
educational institutions
Layer 2-4 Intelligence
The 8500 series packs a lot of features
in one rack unit. With advanced
AlliedWare® 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:
‫ ۼۼ‬Ingress and egress rate-limiting to
provision bandwidth QoS support
with IEEE 802.1p and DSCP for
priority traffic.
‫ ۼۼ‬The 8500 series also includes CoS
to DSCP remarking, allowing Layer
2 QoS priorities to be preserved
over the WAN (typically a Layer 3
feature).

Management stacking of up to 24
switches with Enhanced StackingTM
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.
Management Stacking
Stacking provides CLI-based
management of up to 24 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.
