What Is LLDP & LLDP-MED? A Guide To Understanding The Benefits Of These Data Link Technologies

Data link technologies are an integral part of any connected network today. They can help ensure that data is delivered quickly and reliably to the right destinations, regardless of the network size or complexity. Two popular data link technologies are LLDP (Link Layer Discovery Protocol) and LLDP-MED (Media Endpoint Discovery). In this blog post, we’ll explore what these technologies do, their benefits and how you can use them in your next project. Let’s get started!

What is LLDP?

LLDP is a data link layer protocol that allows network devices to discover each other and exchange information about their configuration and capabilities. LLDP-MED is an extension of LLDP that adds support for media-specific attributes such as link speed and duplex mode.

Both LLDP and LLDP-MED are supported by a wide range of vendors, making it easy to deploy in mixed networks. The benefits of these protocols include simplifying network configuration and troubleshooting, reducing downtime, and improving security.

What is LLDP-MED?

LLDP-MED (Link Layer Discovery Protocol – Media Endpoint Discovery) is a variation of LLDP that is specifically designed for media endpoint devices, such as IP phones and IP cameras. LLDP-MED allows these devices to be automatically discovered and configured by network switches, which can greatly simplify deployment and management. LLDP-MED also provides additional information about the endpoint, such as its power requirements, which can be used to optimize power consumption.

The Benefits of LLDP and LLDP-MED

LLDP and LLDP-MED are data link technologies that have a number of benefits. For one, they allow for the discovery of network devices and their capabilities. This allows for easier management of networks and can help to avoid conflicts between devices. Additionally, these technologies can help to optimize network traffic flow and reduce congestion. They can also provide quality of service information, which is useful for managing voice and video traffic.

How to Implement These Technologies

LLDP and LLDP-MED are two data link technologies that offer a number of benefits for networking environments. In this guide, we will explore how to implement these technologies in order to take advantage of their benefits.

First, let’s take a look at LLDP. LLDP is a protocol that allows devices on a network to share information about themselves with each other. This information can include things like the device’s name, its capabilities, and its location on the network. By sharing this information, devices can be configured more easily and problems can be diagnosed more quickly.

To implement LLDP, you will need to configure your devices to send out LLDP information periodically. You will also need to make sure that your devices are able to receive and process LLDP information from other devices on the network. Finally, you will need to configure your network so that it can forward LLDP information between devices as needed.

Now let’s take a look at LLDP-MED. LLDP-MED is an extension of the LLDP protocol that is designed specifically for use in VoIP networks. It allows devices on a VoIP network to share information about their audio quality and their power requirements with each other. This information can be used by network administrators to troubleshoot problems and optimize the performance of the VoIP network.

To implement LLDP-MED, you will need to configure your VoIP devices to send out LLDP-MED information periodically. You will


LLDP and LLDP-MED are powerful data link technologies that have the potential to revolutionize how businesses manage their IT infrastructure. With their ability to monitor, configure, and troubleshoot network devices from a single centralised system, they can dramatically reduce the time and resources spent on maintaining an efficient network. Not only does this save money in the long run but it also increases productivity for businesses of all sizes. At its core, LLDP and LLDP-MED offer numerous advantages when it comes to simplifying your day-to-day operations.
