Switches
Allied Telesis engineers high-performance, high-quality, future-proof products to meet every cutting-edge
voice, video and data networking need, without breaking the budget. From unmanaged and WebSmart
switches to Layer 2 and Layer 3 switches, Allied Telesis produces efficient, streamlined, powerful
products that will last for the life of the network and deliver the highest-possible return on investment.
Fast, Gigabit and 10 Gigabit
Allied Telesis advanced Fast, Gigabit and
10 Gigabit Ethernet Layer 2 and Layer
3 switches are an ideal solution in the
aggregation tier of large networks, for
server farms, data centers or small and
medium businesses. A robust hardware
design provides maximum uptime of
critical services and reliability.

Stackable
Allied Telesis stackable switches offer
chassis-like availability and resiliency,
allowing management of the stack
as a single, large virtual switch while
providing fast inter-switch connectivity.
Stackable switches offer a cost-effective
and scalable switching solution for the
network.

Power over Ethernet
Traditional switches deliver data to
their connected devices. Allied Telesis
PoE switches add an extra dimension,
providing power to wireless access
points, IP phones and IP security
cameras and other connected devices.

VLAN Double Tagging (Q-in-Q)
VLAN double-tagging can be useful
for customers such as Internet Service
Providers (ISP), allowing them to use
Providers (ISP), allowing them to use
VLANs internally while mixing traffic
from clients that is already VLAN
tagged. The first VLAN tag is used by
the ISP to route traffic across their own
network, while the second VLAN tag is
that of the end-user customer. The use

IEEE 802.1x Authentication
This protocol uses an authentication
server to store details of each user
who has been granted access to the
network. The authentication criteria can
be a computer MAC address, but can
also include IP address, username and
password etc. Initially, the switch port
will be blocked, but when a computer
connects, it will only be connected to
the authentication server. If the request
to access the network is granted, then
the switch will be programmed with
the necessary details, such as VLAN
membership. This type of security
simplifies the task of the network

network. The authentication criteria can

administrator. They can keep all of their
security data on a server and not have to
program each switch. This scenario has
the added benefit of allowing users to
connect to any port on the network.

Voice VLAN
Voice VLAN segregates VoIP traffic from
Ethernet traffic and applies it to a higher
QoS. This ensures high voice quality
for phone conversations, as voice and
data traffic share the same switch and
Ethernet ports. It protects time-sensitive
voice traffic from being flooded by
data traffic share the same switch and
Ethernet ports. It protects time-sensitive
voice traffic from being flooded by
other data traffic, such as multicasts and
broadcasts.
sFlow
sFlow is an industry-standard technology
for monitoring high-speed switched
networks. It gives complete visibility
into the use of networks, enabling
performance optimization, accounting
and billing for usage and defense against
security threats. Sampled packets sent to
a collector ensure it always maintains a
real-time view of network traffic.
