Product Overview
The AT-9424T is an ideal Gigabit-to-the-desk
Layer 3 Gigabit switch. It comes in a 1RU form
factor and provides rich QoS and IGMP
capabilities for voice and video enabled
networks.
The relativeaffordability of the AT-9424T makes
high performance Gigabit switching a reality for
small to medium enterprises. It offers an
extensiveset of standards-based features to
ensure ease of management and integration into
existing networks.
Network QoS and IGMP for Video
and Voice-over-IP
Arich offering of voice and video networking
features is incorporated to ensure support for
demanding multimedia networking applications
in the enterprise. Converged networking is
enhanced with QoS/CoS including eight priority
queues for IEEE 802.1p/ToS/DiffServ traffic.
The high performance hardware platform
makes latency a non-issue.The IGMP
implementation on the AT-9424T is capable of
transmitting broadcast quality video throughout
the enterprise network.
Network Security
To address the concern of network attacks in
the form of Denial of Service (DoS), the
AT-9424T, using Layer 2-4 intelligence, can be
deployed to complement WAN firewalls and
PC anti-virus protections to further fortify the
network against malicious attacks.The
AT-9424T comes pre-programmed to detect
six well-known DoS attacks and supports
security features such as IEEE 802.1x (port-
based NetworkAccess Control) and Radius/
TACACS+.
Long-term Relevance
The AT-9424T is the ideal choice for
organizations seeking a long-term switching
solution. In addition to the extensive Layer 2
feature set this switch features Layer 3 switching
for the future flexibility to meet emerging
needs.
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.
