CDP is short for Cisco Discovery Protocol, a data link layer Protocol. Through this Protocol, our network administrator can obtain information about devices that run the CDP Protocol adjacent to each other.

Cisco disables Some uncommon Services 1. Cisco Discovery Protocol CDP is a Cisco dedicated protocol that runs on Layer 2 of all Cisco products, shared basic device information with other directly connected Cisco devices. Independent of media and protocols. Hackers can use CDP information in the investigation and attack again, which is less likely. Because only CDP
What if devices are scattered? Try link layer Discovery Protocol
In a large network, it is very important to know what is connected to the network. The larger the network, the more logical and physical it is-the harder it is to clarify its topology. In addition, redundant links and link aggregation will greatly increase the difficulty of clarifying the interconnection between devices in the network. In addition, the problem persists. Hybrid use of network products from different vendors will ma

As a result, users have locked the primary protection data for the company's CDP into Windows business Systems, VMware
