AT-9448Ts/XP
| 48 Port 10/100/1000T Managed Layer 3 Switch
Network Security
To address the concern of network attacks
in the form of Denial of Service (DoS), the
AT-9448Ts/XP, 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-9448Ts/XP 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/ .
Long-term Relevance
The AT-9448Ts/XP is the ideal choice for
organizations seeking a long-term switching
solution. In addition to the extensive Layer 2
feature set this switch features 10GbE support
and Layer 3 switching for the future flexibility
and the capacity required to meet emerging
needs. Optional redundant power supplies are
also available to further increase the service life
of this switch.
