Product Description

With the heightened concern for Denial of Services attacks, Allied Telesis is focusing on the security features within its products. Assisted by the L2 through L4 intelligence, network administrators can deploy the AT-8500 as a complement to WAN firewalls and PC anti-virus software to fortify networks against attacks.The AT-8500 switches are programmed to detect six well-known DoS attacks, and coupled with security features such as 802.1x (Port Based Network Access Control) and Radius/ TACACS+, the AT-8500 series offers Tiered Security on each port. Deploying Tiered Security within unsecured areas of corporate offices-such as meeting rooms and lounges-provides cost-effective protections at the network layer. Today's global economic climate pushes network administrators to focus on managing capital spending. One way to keep costs low is to allocate resources efficiently. Allied Telesis has designed the AT-8500 series to allow smart management of network resources with two key features: (a) Ingress and Egress rate-limiting to provision bandwidth QoS support with 802.1p and DiffServ for priority traffic and (b) The AT-8500 Series also includes CoS to DSCP remarking, allowing layer 2 QoS priorities to be preserved over the WAN (typically a Layer 3 feature). The AT-8500 series can be pre-configured to control bandwidth-wasting traffic-such as music streaming to the desktops-by dynamically lowering the priority and limiting bandwidths to a mere trickle without completely blocking it.The same features can benefit metro providers as well, allowing them to offer bandwidth provisioning and QoS priority as premium service to customers.

Main Features:

  • L2-L4 Intelligence: Packet look-up at MAC, IP, TCP/UDP layers For QoS,ACL, Mirroring, Rate-Limiting
  • Advanced Security: DoS Attack Detection and Reporting Radius/ TACACS+ Port Security Secure Telnet 802.1x
  • L2-L4 ACL
  • Advanced Services: Rate-Limiting (Ingress & Egress) 4 levels of Services 802.1p based Class of Service
  • L2 Redundancy: 802.1s, Multiple STP (compatible with PVST+) 802.3ad, Link Aggregation 802.1D, Spanning Tree 802.1w, Rapid STP
  • POE capable: 802.3af compliant
