4.4 DHCP Relay

The section describes how to forward DHCP requests to another specific DHCP servers via DHCP relay. The DHCP servers may be on another network.

4.4.1 Configuration

This section describes how to configure DHCP Relay setting including:

-Relay Mode (Enabled and Disabled)

-Relay Server IP setting

-Relay Information Mode (Enabled and Disabled)

-Relay Information Mode Policy (Replace, Keep and Drop)

Web Interface

To configure a DHCP Relay in the Web interface:

1.Select “Enabled” in the Relay Mode of DHCP Relay Configuration.

2.Specify Relay Server IP address.

3.Select “Enabled” in the Relay Information Mode of DHCP Relay Configuration.

4.Specify Relay (Replace, Keep and Drop) in the Relay Information Mode of DHCP Relay Configuration.

5.Click Save.

Figure 4-9. The DHCP Relay Configuration screen.

Parameter Description

Relay Mode: Indicates the DHCP relay mode operation. Possible modes are:

-Enabled:Enable DHCP relay mode operation. When DHCP relay mode operation is enabled, the agent forwards and transfers DHCP messages between the clients and the server when they are not in the same subnet domain. And the DHCP broadcast message won’t be flooded for security considerations.

-Disabled: Disable DHCP relay mode operation.

Relay Server: Indicates the DHCP relay server IP address. A DHCP relay agent is used to forward and to transfer DHCP messag- es between the clients and the server when they are not in the same subnet domain.

Relay Information Mode: Indicates the DHCP relay information mode option operation. Possible modes are:

-Enabled: Enable DHCP relay information mode operation. When DHCP relay information mode operation is enabled, the agent inserts specific information (option 82) into a DHCP message when forwarding to DHCP server and removes it from a DHCP message when transferring to DHCP client. It only works when DHCP relay operation mode is enabled.

Disabled: Disable DHCP relay information mode operation.

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.
