Configuring Switches in a Stack

Configuring Switches in a Stack

The information in the following sections is important to understand A2 switch operation and installations in a stack installation.

About SecureStack A2 Switch Operation in a Stack

The SecureStack A2 products are stackable switches that can be adapted and scaled to help meet your network needs. These switches provide a management platform and uplink to a network backbone for a stacked group of up to eight A2 switches.

Once installed in a stack, the switches behave and perform as a single switch. As such, you can start with a single switch and add more switches as your network expands. You can also mix different products in the same family in a single stack to provide a desired combination of port types and functions to match the requirements of individual applications. In all cases, a stack of switches performs as one large product, and is managed as a single network entity.

When switches are installed and connected as described back in “Connecting Stacking Cables” on page 3‐11, the following occurs during initialization:

•The switch that will manage the stack is automatically established and is referred to as the Manager switch.

•All other switches are established as Member switches in the stack.

•The hierarchy of the switches that will assume the function of backup manager is also determined in case the current manager malfunctions, is powered down, or is disconnected from the stack.

•The Console port on the manager switch remains active for out‐of‐band (local) switch management, but the Console port on each member switch is deactivated. This enables you to set the IP address and system password using a single Console port. Now each switch can be configured locally using only the manager’s Console port, or in‐band using a remote device and the CLI set of commands described in this section. For procedures used for various types of connections to the Console port, refer to “Connecting to Console Port for Local Management” on page 3‐20.

Once a stack is created (more than one switch is interconnected), the following occurs:

1.Switch (unit) IDs are arbitrarily assigned on a first‐come, first‐served basis.

2.Switch IDs are saved against each module. Then, every time a board is power‐cycled, it will initialize with the same switch ID. This is important for port‐specific information (for example: fe.4.12 is the 12th Fast Ethernet port on switch number 4).

A2H124-24FX specifications

Enterasys Networks A2H124-24FX is a high-performance network switch designed to meet the demands of modern data centers and enterprise environments. This switch exemplifies the blend of reliability, scalability, and advanced features that enterprises require to ensure seamless connectivity and data management.

One of the main features of the A2H124-24FX is its 24 Fast Ethernet (10/100) ports. These ports provide a robust foundation for connecting various devices within a network, making it ideal for workplaces that require extensive connectivity options. Additionally, the switch supports up to 4 Gigabit SFP (Small Form-factor Pluggable) uplink ports, which facilitate high-speed connections to backbone switches or routers, catering to bandwidth-intensive applications.

Another significant characteristic of the A2H124-24FX is its support for Power over Ethernet (PoE). This technology enables the switch to deliver power to connected devices such as IP phones, wireless access points, and security cameras through the same Ethernet cable that transmits data. This feature not only reduces the need for additional power supplies but also streamlines installation processes, reducing overall operational costs.

Security is a paramount concern for any enterprise network, and the A2H124-24FX addresses this through various advanced security features. It includes support for IEEE 802.1X Network Access Control, which ensures that only authenticated users can access the network. Additionally, it provides features such as MAC address filtering and VLAN support to segment network traffic and enhance overall security.

In terms of management, the Enterasys Networks A2H124-24FX is equipped with a user-friendly interface that allows network administrators to configure and monitor the switch effortlessly. It supports both CLI (Command Line Interface) and web-based management, providing flexibility depending on user preference.

This switch also supports advanced Layer 2 and Layer 3 capabilities, including Quality of Service (QoS) features that help prioritize traffic, ensuring that critical applications receive the necessary bandwidth for optimal performance.

In conclusion, the Enterasys Networks A2H124-24FX combines functionality, security, and ease of management, making it an ideal choice for businesses looking to enhance their network infrastructure. Its robust features and reliable performance can effectively support the complex demands of modern networking environments.
