AT-9448T/SP
Layer 3 switch with 48 ports 10/100/1000T
plus 4 combo SFP bays
Product Overview
As a member of the 9400 series the
AT-9448T/SP is a managed Gigabit Ethernet
switch with a 1RU form factor and rich QoS
functionality. It is rack-mountable and supports
DoS attack protection.
The AT-9448T/SP is an ideal choice for small to
medium enterprises that need rich QoS
functionality and Gigabit connectivity. It offers an
extensive set of management features and
advanced QoS functionality deliversLayer 2/4
ready traffic management for VoIP networks. A
managed Gigabit Ethernet switch the
AT-9448T/SP is ready to meet the Gigabit
networking needs at the access tier of any
organization. Implemented protocols and
features are standards-based to ensure ease of
management and integration into existing
networks.
Smarter, More Secure and
More Cost-Effective
The AT-9448T/SP is a Layer 3 managed Gigabit
switch for the access edge that brings enhanced
security and intelligence to Gigabit networks.
The cost-effective AT-9448T/SP offers advanced
attack detection and suppression capabilities
for increased security and advanced QoS to
support converged applications.
The 9400 series provides the perfect
solution for:
•Traditional Enterprise LAN (wiring closet)
•Service-provisioned Leased Offices or MTUs
•Security-conscious Government Institutions
•Security-conscious Financial Institutions
•Cost/security-conscious Educational
Institutions
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/DiffServtraffic.
The platforms high performance hardware
makes latency a non-issue and IGMP
implementation on the AT-9448T/SP is capable
of transmitting broadcast quality video
throughout the enterprise network.
Network Security
Toaddress the concern of network attacks in
the formof Denial of Service (DoS), the
AT-9448T/SP, 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-9448T/SP comes pre-programmed to detect
six well known DoS attacks and supports
security features such as IEEE 802.1x (port-
based Network Access Control) and Radius/
TACACS+.
Management Stacking
Stacking provides CLI-based management of up
to 24 switches with the same effort as for one
switch.The Allied T
elesis solution uses open
standards interfaces as stacking links so that
many switches can be stacked across different
sites.
