VLAN Configuration

VLANs provide greater network efficiency by reducing broadcast traffic, and allow you to make network changes without having to update IP addresses or IP subnets. VLANs inherently provide a high level of network security since traffic must pass through a configured Layer 3 link to reach a different VLAN.

This switch supports the following VLAN features:

Up to 255 VLANs based on the IEEE 802.1Q standard

Distributed VLAN learning across multiple switches using explicit or implicit tagging

Port overlapping, allowing a port to participate in multiple VLANs

End stations can belong to multiple VLANs

Passing traffic between VLAN-aware and VLAN-unaware devices

Priority tagging

Assigning Ports to VLANs

Before enabling VLANs for the switch, you must first assign each port to the VLAN group(s) in which it will participate. By default all ports are assigned to VLAN 1 as untagged ports. Add a port as a tagged port if you want it to carry traffic for one or more VLANs, and any intermediate network devices or the host at the other end of the connection supports VLANs. Then manually assign ports on the other VLAN-aware network devices along the path that will carry this traffic to the same VLAN(s). However, if you want a port on this switch to participate in one or more VLANs, but none of the intermediate network devices nor the host at the other end of the connection supports VLANs, then you should add this port to the VLAN as an untagged port.

Note: VLAN-tagged frames can pass through VLAN-aware or VLAN-unaware network interconnection devices, but the VLAN tags should be stripped off before passing it on to any end-node host that does not support VLAN tagging.

VLAN Classification – When the switch receives a frame, it classifies the frame in one of two ways. If the frame is untagged, the switch assigns the frame to an associated VLAN (based on the default VLAN ID of the receiving port). But if the frame is tagged, the switch uses the tagged VLAN ID to identify the port broadcast domain of the frame.

One of its standout features is the support for Ethernet Flow Control, which significantly reduces data loss during peak traffic loads. This is essential for businesses that rely on real-time data processing and streaming.

In terms of scalability, the VS4512 supports up to 48 Gigabit Ethernet ports, which can be expanded using four 10 Gigabit SFP+ uplink ports. This flexibility allows enterprises to customize their network architecture to meet their growing demands, whether they are scaling up for more users or enhancing service capabilities.

The VS4512DC, on the other hand, is the DC version tailored for data centers. It offers similar features as the VS4512 but includes enhancements for power efficiency and redundancy, ensuring that operations can continue smoothly even in power outage scenarios. The VS4512DC features dual power supplies and advanced thermal management, allowing for improved heat dissipation and lower operational costs.

Both models support advanced Layer 3 routing capabilities, enabling efficient traffic management across complex networks. They also incorporate features like VLAN segmentation and link aggregation, which facilitate better bandwidth utilization and improved network security.

Security is another cornerstone of these switches, with features such as DHCP snooping, port security, and storm control to mitigate risks associated with unauthorized access and network congestion.

In summary, the Accton Technology VS4512 and VS4512DC switches represent significant advancements in networking technology, equipped with a comprehensive set of features tailored for modern enterprise needs. With their scalability, robust performance, and focus on security, these switches are positioned to meet the challenges of today's fast-paced digital environments, making them a preferred choice for organizations aiming to enhance their network infrastructure.
