Overview of the Allied Telesis AT-9000/28SP

The Allied Telesis 9000/28SP is a high-performance Layer 2 28-port (SFP) Gigabit edge Ethernet switch offering advanced enterprise features at an affordable price. With an AlliedWare Plus command line interface (CLI) and its own Web interface, this eco-friendly switch helps reduce power consumption and minimise noise.

The 9000 series provides enhanced stacking of up to 24 units that can be remotely managed as a single IP across multiple sites. Features such as IEEE 802.lx port-based authentication, Microsoft Network Access and Symantec Network Access Control provide security at the network edge. This is facilitated by protocols such as IEEE 802.lx port-based identification, which guarantee that only known users are connected to the network, ensuring data protection. Unknown users who physically connect can be isolated to a predetermined part of the network, offering guest benefits such as Internet access, while ensuring the integrity of private network data.

With secure management, only authorised administrators gain access to the management interface of devices in the 9000 series. Security protocols such as SSL, SSH and SNMPv3 facilitate this protection for both local or remote connections.

Access control lists (ACLs) enable inspection of incoming frames and classification based on various criteria. Specific actions can then be applied to these frames to more effectively manage network traffic.

Powerful line rate performance makes this switch ideal for brand offices or the wiring closet of larger offices. The state-of-the-art QoS capability of these products ensures reliable delivery of advanced network services such as voice and video, while effectively controlling the continually increasing traffic needs of today's networks.
