AT -9448Ts/XP

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/ TACACS+.

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.
