D-Link xStack Switch Series: Meeting the Need at the Edge of the Network 10
D-Link Systems, Inc.

Comprehensive Security
D-Link's xStack Series provides a complete set of security features for connectivity and access
control. The features includes Access Control Lists (ACLs) based on MAC address, switch port,
IP address, and/or TCP/UDP port numbers, 802.1x user authentication and MAC address control.
The xStack also provides central management for administration access via
TACACS/TACACS+ and RADIUS. Together with network application control, this security
ensures that not only proper user access is served, but malicious traffic is also prevented from
spreading across the network.
Network Login and 802.1x
Every user on every port can be authenticated so the network is protected at the most common
point of attack, the edge. xStack Series switches can immediately reject users not authorized to
enter the switch or network. Unauthorized users cannot cause problems in the network because
they are unable enter the network and therefore cannot enter the network unless authorized by
the xStack switch’s web-based or 802.1x based Network Login security features.

Wire Speed Access Control Lists (ACLs)
ACLs are powerful security tools and the use of ACLs in networks is likely to increase as a way
to combat security threats. However, the value of ACLs is diminished if, by applying them,
traffic slows down, creating a congestion point. The xStack Series delivers wire speed ACLs on
every port for maximum security while maintaining maximum throughput. With xStack Series
switches an IT manager can turn on ACLs whenever they are needed without worrying about
disrupting business applications or reducing productivity.
