VLAN Configuration

Ingress Filtering – Determines how to process frames tagged for VLANs for which the ingress port is not a member. (Default: Disabled)

-Ingress filtering only affects tagged frames.

-If ingress filtering is disabled and a port receives frames tagged for VLANs for which it is not a member, these frames will be flooded to all other ports (except for those VLANs explicitly forbidden on this port).

-If ingress filtering is enabled and a port receives frames tagged for VLANs for which it is not a member, these frames will be discarded.

-Ingress filtering does not affect VLAN independent BPDU frames, such as STP. However, they do affect VLAN dependent BPDU frames, such as GMRP.

GARP Join Timer* – The interval between transmitting requests/queries to participate in a VLAN group. (Range: 20-1000 centiseconds; Default: 20)

GARP Leave Timer* – The interval a port waits before leaving a VLAN group. This time should be set to more than twice the join time. This ensures that after a Leave or LeaveAll message has been issued, the applicants can rejoin before the port actually leaves the group. (Range: 60-3000 centiseconds; Default: 60)

GARP LeaveAll Timer* – The interval between sending out a LeaveAll query message for VLAN group participants and the port leaving the group. This interval should be considerably larger than the Leave Time to minimize the amount of traffic generated by nodes rejoining the group.

(Range: 500-18000 centiseconds; Default: 1000)

Mode – Indicates VLAN membership mode for an interface. (Default: 1Q Trunk)

-1Q Trunk – Specifies a port as an end-point for a VLAN trunk. A trunk is a direct link between two switches, so the port transmits tagged frames that identify the source VLAN. However, note that frames belonging to the port’s default VLAN (i.e., associated with the PVID) are sent untagged.

-Hybrid – Specifies a hybrid VLAN interface. The port may transmit tagged or untagged frames.

Trunk Member – Indicates if a port is a member of a trunk. To add a trunk to the selected VLAN, use the last table on the VLAN Static Table page.

*Timer settings must follow this rule: 2 x (join timer) < leave timer < leaveAll timer

It boasts a compact 1U design, making it highly efficient for space-constrained environments. 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.
