Chapter 4: Security

-Shutdown: Indicates that the port is shut down by the Limit Control module. This state can only be shown if Action is set to Shutdown or Trap & Shutdown.

•Re-open Button: If a port is shutdown by this module, you may reopen it by clicking this button, which will only be enabled if this is the case. For other methods, refer to Shutdown in the Action section.

NOTE: That clicking the reopen button causes the page to be refreshed, so unsaved changes will be lost.

•Icon, upper right of screen (Refresh): Click to refresh the Port Security information manually.

•Buttons:

-Save: Click to save changes.

-Reset: Click to undo any changes made locally and revert to previously saved values.

4.7.2 Switch Status

This section shows the Port Security status. Port Security is a module with no direct configuration. Configuration comes indirectly from other modules—the user modules. When a user module has enabled port security on a port, the port is setup for software- based learning. In this mode, frames from unknown MAC addresses are passed on to the port security module, which in turn asks all user modules whether to allow this new MAC address to forward or block it. For a MAC address to be set in the forward- ing state, all enabled user modules must unanimously agree on allowing the MAC address to forward. If only one chooses to block it, it will be blocked until that user module decides otherwise. The status page is divided into two sections—one with a legend of user modules and one with the actual port status.

Web Interface

To configure a Port Security Switch Status Configuration in the Web interface: Check “Auto-refresh.”

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.
