x220 Series

Gigabit Edge Switches

The Allied Telesis x220 Series are fully-managed high-performing Gigabit Layer 3 switches. Integrated security features, plus 28 SFP or 48 Gigabit copper ports, make them the ideal choice for long-distance fiber or high-density copper connectivity at the edge of the network.

x220 Series

Overview

The x220-28GS features 24 x 100/1000X SFP slots and 4 x 100/1000X SFP uplinks to provided extended reach at the network edge in distributed environments. Secure data transfer is ensured with Allied Telesis Active Fiber Monitoring (AFM) preventing data eavesdropping on all short and long-distance fiber links.

The x220-52GP/GT have 48 x 10/100/1000T RJ-45 copper ports and 4x 100/1000X SFP uplinks. The Power over Ethernet Plus (PoE+) model (52GP) is an ideal solution for connecting and remotely powering wireless access points, IP video surveillance cameras and IP phones.

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

Resilient

Allied Telesis Ethernet Protection Switched Ring (EPSRing) 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 entire 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.

Secure

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

Network Access Control (NAC) gives unprecedented control over user access to the network, successfully mitigating threats to network infrastructure.

The x220 Series use 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, policy-based storm protection and packet storm protection.

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

Effortless management

The x220 Series runs the advanced AlliedWare Plu 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.

The web-based Graphical User Interface (GUI) is an easy-to-use and powerful management tool, with comprehensive monitoring facilities.

Key Features

Allied Telesis Autonomous Management Framework (AMF)

  • AMF is a sophisticated suite of management tools that provide a simplified approach to network management. Common tasks are automated or made so simple that the everyday running of a network can be achieved without the need for highly-trained, and expensive, network engineers. Powerful features like centralized management, auto-backup, auto-upgrade, auto-provisioning and auto-recovery enable plug-and-play networking and zero-touch management.
  • AMF secure mode encrypts all AMF traffic, provides unit and user authorization, and monitors network access to greatly enhance network security.

Active Fiber Monitoring (AFM)

  • AFM prevents eavesdropping on fiber communications by monitoring received optical power. If an intrusion is detected, the link can be automatically shut down, or an operator alert can be sent.

Power over Ethernet Plus (PoE+)

  • With PoE, a separate power connection to media endpoints such as IP phones and wireless access points is not necessary. PoE+ reduces costs and provides even greater flexibility, providing the capability to connect devices requiring more power (up to 30 Watts) such as pan, tilt and zoom security cameras.

Continuous PoE

  • Continuous PoE allows the switch to be restarted without affecting the supply of power to connected devices. Smart lighting, security cameras, and other PoE devices will continue to operate during a software upgrade on the switch.

Ethernet Protection Switched Ring (EPSRing)

  • EPSRing allows several x220 switches to form a protected ring capable of recovery within as little as 50ms. This feature is perfect for high availability in enterprise networks.

G.8032 Ethernet Ring Protection

  • G.8032 provides standards-based high-speed ring protection, that can be deployed stand-alone, or interoperate with Allied Telesis EPSR.
  • Ethernet Connectivity Fault Monitoring (CFM) proactively monitors links and VLANs, and provides alerts when a fault is detected.

Access Control Lists (ACLs)

  • The x220 Series features industry-standard access control functionality through ACLs. ACLs filter network traffic to control whether packets are forwarded or blocked at the port interface. This provides a powerful network security mechanism to select the types of traffic to be analyzed, forwarded, or influenced in some way. An example of this would be to provide traffic flow control.

VLAN ACLs

  • Simplify access and traffic control across entire segments of the network. ACLs can be applied to a VLAN as well as a specific port.

Easy To Manage

  • The AlliedWare Plus operating system incorporates an industry standard CLI, facilitating intuitive manageability.
  • With three distinct modes, the CLI is very secure, and the use of SSHv2 encrypted and strongly authenticated remote login sessions ensures CLI access is not compromised.
 

Storm protection

Advanced packet storm control features protect the network from broadcast storms:

  • Bandwidth limiting minimizes the effects of the storm by reducing the amount of flooding traffic.
  • Policy-based storm protection is more powerful than bandwidth limiting. It restricts storm damage to within the storming VLAN, and it provides the flexibility to define the traffic rate that creates a broadcast storm. The action the device should take when it detects a storm can be configured, such as disabling the port from the VLAN or shutting the port down.
  • Packet storm protection allows limits to be set on the broadcast reception rate, multicast frames and destination lookup failures. In addition, separate limits can be set to specify when the device will discard each of the different packet types.

Loop protection

  • Thrash limiting, also known as Rapid MAC movement, detects and resolves network loops. It is highly user-configurable—from the rate of looping traffic to the type of action the switch should take when it detects a loop.
  • With thrash limiting, the switch only detects a loop when a storm has occurred, which can potentially cause disruption to the network. To avoid this, loop detection works in conjunction with thrash limiting to send special packets, called Loop Detection Frames (LDF), that the switch listens for. If a port receives an LDF packet, one can choose to disable the port, disable the link, or send an SNMP trap.

Spanning Tree Protocol (STP) Root Guard

  • STP root guard designates which devices can assume the root bridge role in an STP network. This stops an undesirable device from taking over this role, where it could either compromise network performance or cause a security weakness.

Bridge Protocol Data Unit (BPDU) protection

  • BPDU protection adds extra security to STP. It protects the spanning tree configuration by preventing malicious DoS attacks caused by spoofed BPDUs. If a BPDU packet is received on a protected port, the BPDU protection feature disables the port and alerts the network manager.

Tri-authentication

  • Authentication options on the x220 Series include alternatives to 802.1x port-based authentication, such as web authentication, to enable guest access and MAC authentication for end points that do not have an 802.1x supplicant. All three authentication methods—802.1x, MAC-based and Web-based—can be enabled simultaneously on the same port, resulting in tri-authentication.

TACACS+ Command Authorization

  • Centralize control of which commands may be issued by a specific user of an AlliedWare Plus device. TACACS+ command authorization complements authentication and accounting services for a complete AAA solution.

Optical DDM

  • Most modern optical SFP/SFP+/XFP transceivers support Digital Diagnostics Monitoring (DDM) functions according to the specification SFF-8472. This enables real time monitoring of the various parameters of the transceiver, such as optical output power, temperature, laser bias current and transceiver supply voltage. Easy access to this information simplifies diagnosing problems with optical modules and fiber connections.

VLAN Mirroring (RSPAN)

  • VLAN mirroring allows traffic from a port on a remote switch to be analysed locally. Traffic being transmitted or received on the port is duplicated and sent across the network on a special VLAN.

Find Me

  • In busy server rooms comprised of a large number of equipment racks, it can be quite a job finding the correct switch quickly among many similar units. The “Find Me” feature is a simple visual way to quickly identify the desired physical switch for maintenance or other purposes, by causing its LEDs to flash in a specified pattern.

IPv6 Support

  • With the depletion of IPv4 address space, IPv6 is rapidly becoming a mandatory requirement for many government and enterprise customers. To meet this need, now and into the future, the x220 Series supports IPv6 forwarding in hardware and features MLD snooping for efficient use of network bandwidth.

sFlow

  • sFlow is an industry-standard technology for monitoring high-speed switched networks. It provides complete visibility into network use, enabling performance optimization, usage accounting/billing, and defense against security threats. Sampled packets sent to a collector ensure it always has a real-time view of network traffic.
x220 Distributed retail network

Distributed retail network

The growth of large retail shopping complexes, and open-air malls (as shown in the diagram above) have increased the need for high performing networks. The convergence of data from visitor information kiosks, monitoring sensors, security management, and point of sale systems requires a resilient solution.

The x220 Series supports Allied Telesis Ethernet Protection Switched Ring (EPSRing) to ensure distributed network segments have high-speed access to online systems. Continuous traffic flow is enabled with failover in a little as 50ms in the case of an unscheduled device outage or link failure.

With 28 SFP ports, the x220-28GS extends network reach to enable access connectivity right around the retail precinct, or similarly an education campus, manufacturing plant, or large distributed business. All fiber links are kept secure with Active Fiber Monitoring, which detects attempted data eavesdropping and protects against intrusion.

To simplify and automate network management, Allied Telesis Autonomous Management Framework automatically backs-up the entire network, and provides plug-and-play network growth and zero-touch unit replacement.

Network convergence

The convergence of network services in the Enterprise has led to increasing demand for highly available networks with minimal downtime. Diagram 1 shows x220 switches with high performance EPSR connectivity to the SwitchBlade x8106 core chassis. This topology provides recovery in as little as 50ms, if required.

Network flexibility

Flexible network deployment is facilitated by the x220 PoE+ models, as shown in the Campus network in diagram 2. With the growth of wireless networking and digital security, the x220 PoE+ models are ideal supplying connectivity and power at the network edge, supporting the full 30 watts of PoE+.

AMF provides an easy yet powerful solution for managing multiple devices with plug-and-play simplicity.
