Product Description

Allied Telesis x220-28GS Manageable Layer 3 Switch

Allied Telesis x220-28GS Manageable Layer 3 Switch - 3 Layer Supported - Modular - Optical Fiber - 1U High - Rack-mountable The x220-28GS comprises 24 x 100/1000X SFP slots, and 4 x 100/1000X SFP uplinks, to support extended reach at the network edge in distributed environments. Secure data transfer is ensured with Allied Telesis Active Fiber Monitoring preventing eavesdropping of sensitive data on all short and long distance fiber links.

A comprehensive feature-set provides an excellent access solution for today's networks, with high performance gigabit throughput.

Allied Telesis Ethernet Protection Switched Ring (EPSRingTM) enables distributed network segments to have resilient high-speed access to online resources and applications, and provides continuous traffic flow even during unscheduled outages.

Powerful network management
Meeting the increased management requirements of modern converged networks, Allied Telesis Autonomous Management Framework (AMF) automates many everyday tasks including configuration management. The complete network can be managed as a single virtual device with powerful centralized management features. Growing the network can be accomplished with plug-and-play simplicity, and network node recovery is fully zero-touch.

AMF secure mode increases network security with management traffic encryption, authorization, and monitoring.

Network security is guaranteed, with powerful control over network traffic types, secure management options, and other multi-layered security features built right into the x220-28GS.

Network Access Control (NAC) gives unprecedented control over user access to the network, in order to mitigate threats to network infrastructure.

The Allied Telesis x220-28GS uses 802.1x port-based authentication, in partnership with standards-compliant dynamic VLAN assignment, to assess a user's adherence to network security policies and either grant access or offer remediation. Tri-authentication ensures the network is only accessed by known users and devices. Secure access is also available for guests.

Security from malicious network attacks is provided by a comprehensive range of features such as DHCP snooping, STP root guard, BPDU protection and access control lists. Each of these can be configured to perform a variety of actions upon detection of a suspected attack.

Network protection
Advanced storm protection features include bandwidth limiting, policybased storm protection and packet storm protection.

Network storms are often caused by cabling errors that result in a network loop. The x220-28GS provides features to detect loops as soon as they are created. Loop detection and thrash limiting take immediate action to prevent network storms.

The x220-28GS runs the advanced AlliedWare Plus™ fully featured operating system, delivering a rich feature set and an industry-standard Command Line Interface (CLI). This reduces training requirements and is consistent across all AlliedWare Plus devices, simplifying network management.
