3.16 QoS

The switch supports four QoS queues per port, with strict or weighted fair queuing scheduling. It supports QoS Control Lists (QCL) for advance programmable QoS classification, based on IEEE 802.1p, Ethertype, VID, IPv4/IPv6 DSCP and UDP/TCP ports and ranges.

High flexibility in the classification of incoming frames to a QoS class. The QoS classification looks for information up to Layer 4, including IPv4 and IPv6 DSCP, IPv4 TCP/UDP port numbers, and user priority of tagged frames. This QoS classification mechanism is implemented in a QoS control list (QCL). The QoS class assigned to a frame is used throughout the device for providing queu- ing, scheduling, and congestion control guarantees to the frame according to what was configured for that specific QoS class.

The switch supports advanced memory control mechanisms, providing excellent performance of all QoS classes under any traffic scenario, including jumbo frame. It also features a super priority queue with dedicated memory and the highest priority when instances of arbitration become necessary. The ingress super priority queue permits traffic recognized as CPU traffic to be received and queued for transmission to the CPU even when all the QoS class queues are congested.

3.16.1 Port Classification

This section describes how to configure the basic QoS Ingress Classification settings for all switch ports. The settings relate to the currently selected unit, as shown in the page header.

Web Interface

To configure the QoS Port Classification parameters in the Web interface:

1.Click Configuration, QoS, Port Classification.

2.Scroll to select QoS class, DP Level, PCP, and DEI parameters.

3.Click ”Save“ to save the setting.

4.To cancel the setting, click the Reset button to revert to previously saved values.

LPB2848A, LPB2826A, LPB2810A, PoE+ Gigabit Managed Switch Eco specifications

The Black Box PoE+ Gigabit Managed Switch series, including the models LPB2810A, LPB2826A, and LPB2848A, presents a robust solution for businesses looking to enhance their network efficiency and reliability. Designed to support the growing demand for Power over Ethernet (PoE) devices, these switches provide the perfect backbone for modern network infrastructures.

One of the most significant features of this series is its PoE+ capability, which allows it to deliver power and data over a single Ethernet cable. This functionality simplifies cabling and installation, making it easier to deploy PoE devices such as IP cameras, VoIP phones, and wireless access points. The LPB2810A offers 8 PoE+ ports, the LPB2826A ups the ante with 24 ports, and the LPB2848A provides a whopping 48 ports, each capable of delivering up to 30 watts of power per port.

The managed switch system ensures that users can customize and optimize their network performance. With advanced features such as VLAN support, Quality of Service (QoS), and link aggregation, organizations can effectively manage traffic, prioritize critical applications, and potentially enhance overall network security. Furthermore, these switches support Layer 2 and Layer 3 functionalities, which allows for greater flexibility when implementing routing policies.

Another critical aspect of the LPB series is its built-in security features. The switches come equipped with advanced security protocols, including IEEE 802.1X port-based access control, which enables network administrators to authenticate devices before granting access to the network. This significantly reduces the risk of unauthorized access and ensures data integrity across the connected devices.

The Black Box PoE+ Gigabit Managed Switches are designed with reliability and ease of use in mind. Their fanless design promotes silent operation, making them ideal for deployment in both office environments and data centers. Additionally, the switches offer a user-friendly web-based interface and CLI options for straightforward management and configuration, catering to both novice and seasoned network administrators.

In conclusion, the Black Box PoE+ Gigabit Managed Switch series, featuring models LPB2810A, LPB2826A, and LPB2848A, stands out with its power-efficient design, extensive port options, and advanced security measures. These switches are an excellent choice for organizations that require a dependable and scalable networking solution to support their growing Ethernet and PoE device needs.
