Stack function(#1) enables a small startup using a floor switch.
Feature-rich layer 2 functions (e.g. triple authentication, multi-step authentication, loop detection, ring protocol, etc.)
High-performance network authentication enables smooth authentication even with more robust 2048-bit SSL, which has been becoming popular in education and research fields.
Layer 2 distribution switches capable of simple redundancy and unified management
Stack function(#1) enables fast switchover within 1 second in the event of a failure.
Unified management for redundant switches
Stack will be supported in 2014.

  • IPv6 Ready Logo Phase2(Core)(Logo-ID-:02-C-000806)

    IPv6 Ready Logo Phase2(Core)

  • RoHS compliant


Triple authentication

  • Supports three authentication methods (IEEE802.1X, Web, MAC), enabling flexible secure networking.

Multi-step authentication

  • By using two authentication methods together, possible to configure a more robust security system.

Industry-leading web authentication performance

  • Simultaneous authentication of a large number of terminals
  • Smooth authentication even with more robust 2048-bit SSL

Dynamic ACL/QoS

  • Possible to specify Access Control List (ACL) dynamically in authentication, thus enables communication control for each user.

DHCP Snooping

  • Forwards only authorized packets coming from trusted DHCP clients whose IP addresses were issued by DHCP servers.

Quarantine solution

  • Only PCs complying with a security policy can access a network.


  • Supports access control lists for layer 2, layer 3, and layer 4 headers.


  • Port-based VLAN, Tag-VLAN, protocol VLAN, MAC VLAN

Fault Tolerant Network

Non-stop network

  • STP-free redundancy prevents trouble that is caused due to the complexity of using multiple protocols and provides more stable systems.


  • Stack enables multiple switches to operate together as a single switch, enabling simple protocol-free redundancy and unified management.
  • Link aggregation across stacked switches enables fast switchover in the event of a failure.
  • Ethernet cables are used for stacking, which enables long-haul communication between stack members. (To be supported in 2014.)

High Reliability and High Availability

Ring protocol

  • Possible to configure a ring network using the ALAXALA proprietary layer 2 redundancy protocol enabling fast switchover within 1 sec.
  • Possible to configure a high-flexibility, multi-ring network.

High reliability

  • Improves reliability with link aggregation, STP, GSRP aware(Gigabit Switch Redundancy Protocol), uplink redundancy, UDLD, and EtherOAM.

Prevention of a loop failure

  • Loop detection function prevents loops that may be caused by miscabling.

Storm control

  • Storm control prevents the suspension of an entire system when storm has occurred.


  • Granular QoS control enables priority control (for important packets / voice packets), port bandwidth control and so on.

Green IT and Power Saving

Dynamic power saving to cut unnecessary power use

  • Auto power off to cut power to unused ports
  • Device sleep: the switch shifts into the sleep mode according to a predetermined schedule.
  • Scheduling: power consumption is reduced during the periods of low network usage (e.g., nighttime / holidays).

Energy saving design

  • Low power consumption with low power architecture / circuit design and energy saving parts

Fanless models

  • Suitable for use in places that should be noise-free (e.g., conference rooms)
  • No dust accumulation and no moving parts, reducing chance of malfunction. (AX2530S-24T)

Optic Multi-port Models

Optic multi-port models for a large-scale LAN

  • A model with optical fiber ethernet (1000BASE-X) is available for use as a core or distribution switch in enterprise networks.
    AX2530S-2S4X : 24 ports for 1000BASE-X
  • Suitable for networks that require long distance wiring over 100m that UTP cables cannot reach, and for use in noisy environment (e.g. hospital, factory, etc.).


IPv6 Multicast in layer 2 networks

  • Supports MLD snooping.

Operation Management and Maintenance

Unified CLI

  • Unified Command Line Interface enabling easy operation and maintenance

Command-free maintenance

  • Easy maintenance operation (e.g. backup data and update software.) just by inserting an SD card (script) into the switch
