Switch stacking is a networking technology that allows multiple switches to be connected and managed as a single logical unit. This technology offers many benefits, including improved network performance, scalability, and simplified management. In this blog post, we’ll discuss the benefits of switch stacking with Aruba Instant On 1960 switches.

Aruba Instant On 1960 switches are designed for small and medium-sized businesses that require a reliable, secure, and high-performance network. These switches come with built-in switch stacking capabilities, allowing stackable switches to be connected and managed as a single entity. Additionally, they support cloud-managed stacking, enabling remote management of the network. This means you can configure, manage, and monitor your stack of switches via an online portal or mobile app, offering flexibility and ease of use without the need for physical on-site presence. This is particularly beneficial for small businesses looking for a simpler way to deploy and manage their networks efficiently.

What Do You Mean by Stacking?

What Do You Mean by Stacking?

In computer networking, stacking refers to the process of connecting multiple switches together to form a single logical unit. When stacked switches are switch, they operate a single switch with a single device management interface, enabling network switches administrators to manage the entire stack master as a one device through a local web GUI.

Switch stacking is typically accomplished by connecting the other switches together using a specialized stacking cable or through a built-in stacking module. Stacking ports are used to configure and connect switches within a stack, allowing for easier management and high availability. When all the switches are stacked, they share a common backplane, which allows traffic to pass between the switches quickly.

Stacked switches typically provide a number of benefits, including:

-Stacked switches typically provide a number of benefits, including:
  1. Improved Performance: When stackable switches are stacked, they work together to provide increased bandwidth and redundancy, which can improve network performance and availability.

  2. Scalability: As network requirements grow, additional switches can be easily added to the stack, allowing the network switch to scale as needed.

  3. Simplified Management: By managing multiple devices as a single entity, stackable switches can simplify network management and reduce the risk of configuration errors.

  • Multiple IP Addresses: Cloud-managed stacking uses multiple IP addresses for management purposes, allowing dynamic reconfiguration, handling failure scenarios without a reboot, and continuing to operate as a single L2 device even when the connection to the Internet fails.

  1. Cost-Effective: Stackable switches can be more cost-effective than other switches, as they allow multiple switches to be managed as a single entity, reducing the need for additional management and configuration tools.

  • Single Management Interface: Stacking multiple switches together allows them to be configured and managed as a single logical device, providing easy configuration, management convenience, and reliable networks for small businesses.

Stacking on Aruba Network Devices

Stacking on Aruba Network Devices

Aruba Networks, a leading provider of network infrastructure solutions, offers a range of network devices that support stacking technology. Stacking allows multiple network devices to be connected and managed as a single logical unit, providing several benefits to network administrators.

Aruba stacking technology enables a stack of up to 12 network devices to be connected and managed as a single entity, allowing for simplified management, improved network performance, and scalability. With Aruba stacking, network administrators can easily expand their network as needed by simply adding new devices to the stack without requiring any additional configuration. Additionally, Aruba stacking technology includes hybrid stacking, which allows both access and aggregation switches to be stacked together in a single stack, either in a chain or ring topology. This provides scalability, flexibility, and high availability in the network, catering to the resiliency and growth requirements of small businesses.

Aruba network devices, including switches, support stacking technology to provide improved network performance, scalability, and management. The Aruba Instant On 1930 and 1940 switches, for example, support stacking up to eight switches, while the Aruba 2930M and 3810M switches support stacking up to 10 switches.

How to Configure Switch Stacking?

How to Configure Switch Stacking?

Configuring a switch involves several steps that need to be performed in a specific order. Here are the basic steps for configuring switch stacking:

  1. Connect the switches: The first step is to physically connect the switches together using the stacking cables. Depending on the switch model, you may need to use specific stacking cables to ensure compatibility.

  2. Enable stacking: Once the switches are physically connected, you need to enable stacking on each master switch.

  3. Stack manually: As an alternative, you can stack manually by configuring each switch individually. This involves pulling out orange luggage tags and scanning QR codes for each switch. This manual configuration option is part of the cloud-managed stacking process, which allows for dynamic reconfiguration and handling failure scenarios without a reboot, even when the stack loses connectivity to the Internet.

  4. Configure the stack: After enabling stacking on each switch, you can configure the stack settings. This involves assigning a stack ID and configuring the stack management IP address.

  5. Verify the stack: Once the stack is configured, it’s important to verify that the stack is operating as expected. You can do this by checking the stack status on each switch and verifying that all switches in the stack are operational.

  6. Manage the stack: With the stack configured and verified, you can now manage the stack as a single entity. This involves accessing the stack management interface, which allows you to view and configure the entire stack from a single switch.

    Stack Members ID

    In a switch stack, the Stack Members ID is a unique identifier assigned to each switch in the stack. The Stack Members ID helps the master switch to identify and manage each switch in the stack.

    If a switch needs to be replaced, the new switch can adopt the same configurations as the replaced switch, ensuring seamless integration and management.

    The Stack Member ID is important because it determines the order in which switches participate in stack elections. When a switch stack is first formed, the master switch is elected based on the Stack Member ID. The switch with the lowest Stack Member ID is elected as the stack master.

    A Standby switch is a switch that will become the new Active switch if the original Active switch goes offline. In this way, a backup helps maintain the resiliency of the stack.

    Switch Stack vs Chassis

    These are two different approaches to network design that offer unique benefits and drawbacks. Here are some of the key differences between switch stacks and chassis:

    Switch Stacking:

    • In switch stacking, multiple switches are connected together using stack cables to form a single logical unit. Stacking typically supports up to 12 switches, although some vendors may support more.

    • With cloud-managed stacking, the switches can handle failure scenarios without a reboot and continue to function locally. Even when there is a disruption to the connection to the Internet, the stack remains intact and handles error scenarios such as link and switch failure without any help from the cloud management portal.


    • A chassis is a single physical unit that contains multiple network modules or line cards. The modules are typically hot-swappable and added or removed without taking the chassis out of service.

    Ultimately, the choice between switch stacking and chassis depends on the specific needs of the organization.

    Switch Stacking vs Switch Cascading vs Clustering

    Switch Stacking vs Switch Cascading vs Clustering

    Stacking switches, switch cascading, and clustering are all methods for connecting multiple to switch networks together to improve network performance and scalability. Here are the key differences between these methods:

    When switches are connected in a cloud-managed stacking setup, they can be configured and managed remotely with ease, offering flexibility in either a ring or chain topology.

    Switch Stacking:

    • Switch stacking involves connecting switches together using a stacking cable to form a single logical unit. All switches in the stack are managed as a single entity, with a single IP address and management interface.

    Switch Cascading:

    • Switch cascading involves connecting switches together in a hierarchical or daisy-chain configuration. Each switch in the cascade is connected to the previous switch using an uplink port, with the final switch connected to the network.


    • Clustering involves connecting multiple networks together to form a single logical unit, with each switch operating independently.
