Configuring VLANs

This section describes how to create and configure Virtual LANs (VLANs).

VLANs are logical subgroups with a Local Area Network (LAN) which combine user stations and network devices into a single unit, regardless of the physical LAN segment to which they are attached. VLANs allow network traffic to flow more efficiently within subgroups. VLANs use software to reduce the amount of time it takes for network changes, additions, and moves to be implemented.

VLANs have no minimum number of ports, and can be created per unit, per device, or through any other logical connection combination, since they are software-based and not defined by physical attributes.

VLANs function at Layer 2. Since VLANs isolate traffic within the VLAN, a Layer 3 router working at a protocol level is required to allow traffic flow between VLANs. Layer 3 routers identify segments and coordinate with VLANs. VLANs are Broadcast and Multicast domains. Broadcast and Multicast traffic is transmitted only in the VLAN in which the traffic is generated. VLAN tagging provides a method of transferring VLAN information between VLAN groups. VLAN tagging attaches a 4-byte tag to packet headers. The VLAN tag indicates to which VLAN the packets belong. VLAN tags are attached to the VLAN by either the end station or the network device. VLAN tags also contain VLAN network priority information.

Combining VLANs and Generic Attribute Registration Protocol (GARP) allows network managers to define network nodes into Broadcast domains.

When configuring VLANs ensure the following:

•When using this feature, the management VLAN must exist on each 8000S Series device that you want to manage.

•All of the devices in an enhanced stack must use the same management VLAN. Consequently, you must use the following procedure to specify the management VLAN on each slave and master device of an enhanced stack.

•The uplink and downlink ports on each device that are functioning as the tagged or untagged data links between the devices must be either tagged or untagged members of the management VLAN.

•The port on the device to which the management station is connected must be a member of the management VLAN.

This section contains the following topics:

•Defining VLAN Properties

•Defining VLAN Interface Settings

•Defining GVRP

AT-8000S specifications

The Allied Telesis AT-8000S series switches are a range of advanced Layer 2 Ethernet switches designed for efficient networking in various environments. Engineered with performance, reliability, and cost-effectiveness in mind, these switches are ideal for businesses seeking to enhance their network infrastructure.

One of the main features of the AT-8000S series is its high-speed data forwarding capabilities. With support for 10/100/1000 Mbps Ethernet ports, these switches provide fast and reliable connections, enabling seamless data transfer and enhanced communication between devices. The non-blocking switching architecture ensures that full bandwidth is available at all times, maximizing throughput and reducing latency in network traffic.

The AT-8000S series incorporates advanced Layer 2 switching technologies, such as VLAN support, allowing users to segment network traffic for improved performance and security. Virtual Local Area Networks (VLANs) help isolate sensitive data and reduce unnecessary broadcast traffic, enhancing the overall performance of the network.

Quality of Service (QoS) is another significant feature integrated into these switches, prioritizing different classes of network traffic. This functionality ensures that critical applications receive the necessary bandwidth and minimal latency, which is imperative for voice over IP, video conferencing, and other latency-sensitive applications.

In terms of network management, the AT-8000S series provides a variety of options, including an intuitive web-based interface, SNMP support, and the ability to manage switch configurations through console access. This flexibility allows network administrators to monitor performance and manage configurations easily.

The switches are built for durability, featuring a robust design suitable for deployment in various environments, including temperature-sensitive areas. Power over Ethernet (PoE) capability is also available in certain models, allowing network devices like IP cameras and wireless access points to receive power through the same cable as data, simplifying installation and reducing clutter.

Allied Telesis emphasizes security within the AT-8000S series, with features such as port security, DHCP snooping, and IEEE 802.1X authentication to safeguard against unauthorized access and potential threats.

Overall, the Allied Telesis AT-8000S series provides a comprehensive networking solution tailored for modern business needs, combining performance, flexibility, and security to support a growing array of applications and devices within the network.
