What are Stackable Ethernet Switches

  1. Definition and working principle:

    A stacked Ethernet switch is a network device that combines multiple switches into a logical unit through stacking technology. They can be viewed as a single large switch, providing greater flexibility and scalability. Stacked switches are connected to each other through specific stacking links to form a high-performance switch cluster. They share configuration information, management functions and bandwidth to achieve high bandwidth, high throughput and redundancy.

  2. Differences from traditional non-stacked switches:

    • Scalability: Stacked switches allow multiple switches to be connected together to form a logical unit, providing more ports and bandwidth to meet growing network needs. Traditional non-stackable switches can only be expanded through additional links or upper-level switches, limiting available ports and total bandwidth.
    • Management: Stacked switches can be managed centrally, configuring and monitoring the entire stack through a management IP address and a management interface. Traditional non-stacked switches require independent management and configuration of each switch, and the operation is relatively independent.
    • Redundancy: Stacked switches can implement redundant configurations and provide redundancy through multiple physical switches to ensure high network availability. Traditional non-stackable switches often require additional redundancy protocols and links to achieve redundancy.
  3. Basic composition and topology:

    • Stacking Link: A stacking link is a physical link connecting stacked switches, and is usually connected using a special stacking port. Stacking links provide high-bandwidth and low-latency interconnects, allowing data and control information to be shared between switches.
    • Master Switch: In a stack, one switch is designated as the master switch and is responsible for managing the entire stack. The master switch usually has higher processing power and more functions, including stacking configuration, link aggregation, virtual LAN (VLAN) settings, etc.
    • Member Switch: A slave switch is another switch connected to the master switch. They communicate with the master switch over stacking links and forward data to target devices.

Stackable Ethernet switches provide higher scalability, centralized management, and redundancy through stacking technology. Their basic components include stacking links, master switches and slave switches, forming a high-performance switch cluster. This topology makes stacked switches ideal for building large networks and meeting high bandwidth needs.

Flexible network expansion capabilities

Flexible network expansion capability is an important advantage of Stackable Ethernet Switches. The following will discuss its advantages in network expansion and explain how they achieve flexible port expansion through stacking connections, and how to achieve flexible port expansion through stacking connections. Convenience for growing network demands:

  1. Advantages:

    • Port expansion: Stacked switches allow multiple switches to be connected together to form a logical unit, providing more ports. With stacked connections, administrators can gradually increase the number of switches as needed to meet growing network demands without having to replace the entire switch device.
    • Bandwidth expansion: Stacked switches are connected through stacking links to share bandwidth and throughput. This means data can be transmitted in parallel between multiple stacked switches, providing higher overall bandwidth. When the bandwidth of a switch is insufficient, administrators can increase the total bandwidth by adding more switches to achieve flexible bandwidth expansion.
    • Simplified management: Stacked switches can be managed centrally, and the entire stack can be configured and monitored through one management IP address and one management interface. This simplifies network management, allowing administrators to centrally manage the entire stack through a unified interface, rather than having to manage and configure each switch individually.
  2. Stacking connection implements port expansion:

    • Stacking link: A stacking link is a physical link connecting stacked switches, and is usually connected using a special stacking port. Through stacking links, switches can communicate directly with each other and treat the switches in the stack as a whole. In this way, administrators can use multiple switch ports to expand the network to form a logically larger switch.
    • Single management domain: Through stacking connections, stacked switches can share configuration information and management functions. Administrators only need to configure on the master switch, and the configuration information will be automatically propagated to the slave switches to achieve a unified management domain. This makes port expansion and configuration easier, and administrators only need to focus on the master switch rather than configuring each switch individually.
  3. Convenience to meet growing network needs:

    • Flexibility: The flexibility of stacked switches makes network expansion easy. By adding additional switches, administrators can gradually expand the network based on demand without the need for large-scale equipment replacement, saving time and costs.
    • Scalability: Stackable switches provide a highly scalable solution. Because stacked switches share bandwidth and configuration information, more switches can be easily added to meet growing network demands. This scalability makes stackable switches particularly popular in large enterprises, data centers, and growing networks.

In short, stacked Ethernet switches have flexible network expansion capabilities and realize port expansion and bandwidth expansion through stacking connections. Their management simplicity and scalability make it easier to meet growing network demands. Whether extending an existing network or building a new network architecture, stackable switches provide a flexible solution.

High availability and redundancy

High availability and redundancy are important advantages of Stackable Ethernet Switches in the network. The following will introduce their advantages in providing high availability and redundancy and explain how they use redundancy. Link and stack backup realize network redundancy, while emphasizing the importance of stacked switches in critical business and fault recovery:

  1. Advantages:

    • High availability: Stacked switches provide a high-availability network environment through redundant configuration and backup. They can maintain network connectivity when a single device or link fails, reducing the risk of business interruption.
    • Redundancy: Stacked switches allow administrators to configure redundant links and backup devices to ensure redundant paths and backup switches in the network. In this way, if a link or device fails, data traffic can be transmitted through the backup path or backup device to ensure network connectivity and data reliability.
  2. Redundant links and stack backup achieve network redundancy:

    • Redundant links: By setting up redundant links between stacked switches, redundant paths can be provided to transmit data. When the primary link fails, data can continue to be transmitted through the backup link to ensure network connectivity. Redundant links can be implemented using link aggregation technology, which bundles multiple physical links into one logical link to provide higher bandwidth and redundancy.
    • Stacked backup: Stacked switches allow administrators to configure backup devices that can take over network functions if the primary switch fails. The backup device is usually in a slave state in the stack. When the main switch fails, the backup device will automatically take over the functions of the main switch and continue to provide network services. This stacked backup mechanism ensures network continuity and reliability.
  3. Importance of critical business and failure recovery:

    • Critical business: In the modern network environment, many organizations and enterprises rely on the network to run critical businesses. The high availability and redundancy of stacked switches ensure the continuity of key services, reduce the risk of business interruption and data loss, and improve business stability and reliability.
    • Failure recovery: When network equipment or links fail, the redundant configuration and backup equipment of stacked switches can quickly respond and restore network functions. This reduces the impact of failures on network performance and user experience, and reduces troubleshooting and recovery time.

In short, stacked Ethernet switches provide high availability and redundancy through redundant links and stack backup to ensure network connectivity and reliability. In terms of critical business and fault recovery, the functions of stacked switches are crucial, helping organizations and enterprises maintain a highly available network environment and quickly respond to failure situations to ensure business continuity and stability.
