Description

ENTERASYS A2H254-16-RH

The A-Series is a Layer 2 managed Gigabit Ethernet switch designed and manufactured by Enterasys Networks (now part of Extreme Networks). It is part of its “A-Series” product line, known for its ruggedness, high performance, and rich management features. It is primarily targeted at the access layer of enterprise networks, the core of small and medium-sized businesses, and network environments that require reliable connectivity and granular control.

Key Features & Detailed Description

1. Port Configuration

• 16 10/100/1000BASE-T Gigabit Ethernet Ports: All 16 copper ports support auto-negotiation (10/100/1000 Mbps) and auto MDI/MDIX, simplifying cabling by eliminating the need for crossover cables.

• 4 Shared SFP Gigabit Fiber Optic Slots: These 4 SFP slots are shared/multiplexed with the last four 10/100/1000BASE-T ports (ports 13-16). This means for ports 13-16, you can choose to use either the copper connection or insert an SFP transceiver for fiber connectivity, but not both simultaneously. This provides flexible uplink or long-distance connection options.

2. Performance & Architecture

• Switching Capacity: 32 Gbps non-blocking architecture, ensuring all ports can forward traffic at wire speed in full-duplex mode simultaneously without packet loss.

• Forwarding Rate: Up to 23.8 Mpps (Million packets per second).

• MAC Address Table: 16K entries, sufficient for medium-sized network demands.

3. Management & Software

• Operating System: Runs ExtremeXOS (inherited from Enterasys) or a previous Enterasys Network Operating System, providing a robust, stable, and feature-rich Command Line Interface (CLI).

• Management Methods:

  • Command Line Interface (CLI): Offers a powerful configuration experience with industry-standard similarities.

  • Web Interface (WebUI): A web-based graphical interface for intuitive and convenient management.

  • SNMP: Supports v1, v2c, and v3, allowing integration with major network management systems (e.g., SolarWinds, WhatsUp Gold).

  • SSH / Telnet: For secure (SSH) or non-secure (Telnet) remote CLI management.

• Advanced Features:

  • VLAN: Supports 802.1Q VLAN, Port-based VLAN, MAC-based VLAN, etc., for network segmentation.

  • Quality of Service (QoS): Supports 802.1p CoS and IP precedence based on DSCP, with multiple output queues to prioritize critical application traffic like voice and video.

  • Multicast Management: Supports IGMP Snooping for efficient management of multicast traffic (e.g., video streams).

  • Link Aggregation: Supports 802.3ad LACP (Link Aggregation Control Protocol), allowing multiple physical ports to be bundled into a single, logical high-bandwidth link, providing redundancy and increased throughput.

  • Spanning Tree Protocol: Supports STP, RSTP, and MSTP to prevent network loops and provide fast convergence.

  • Security: Supports Port-based security (802.1X), MAC address filtering, ACLs (Access Control Lists), etc.

4. Power & Reliability

• Redundant Hot-swappable Power Supplies (Core feature of the -RH model): Equipped with two hot-swappable AC power supply modules. If one power supply fails, the other automatically takes over, ensuring continuous switch operation and significantly enhancing device reliability and availability.

• Fans: Typically equipped with hot-swappable, redundant fan modules, further enhancing device durability.

• Rack-mountable: Standard 1U height, designed for installation in a 19-inch rack.

Typical Application Scenarios

1. Enterprise Network Access Layer: Provides reliable Gigabit connectivity for office desktops, IP phones, and wireless access points.

2. SMB Core/Aggregation Switch: For smaller networks, it can serve as the core switch, acting as the backbone connecting all access layer devices and servers.

3. Data Center Edge: Used for connecting servers and storage devices; its redundant power feature is well-suited for environments with high availability requirements.

4. Scenarios Requiring Fiber Uplinks: Utilizing its SFP slots, it can connect to core or aggregation switches located in different buildings.

---

Advantages:

• High Reliability: Redundant, hot-swappable power supplies and fans are its standout features, ideal for critical operations.

• Strong Performance: Full wire-speed, non-blocking switching meets the demands of Gigabit environments.

• Rich Management Features: Offers all the advanced features expected from an enterprise-class switch (VLAN, QoS, LACP, etc.).

• Port Flexibility: Shared SFP slots provide flexible choices between copper and fiber connections.

• Rugged and Durable: The Enterasys brand is known for its product quality and stability.
