Network discovery protocols gather device information in Ethernet networks. The extraction of data from AFT (Address Forwarding Tables) achieves this.
These tables are crucial mechanisms that rely on the info for proper functioning. It’s essential to note the significance of AFT tables, ensuring efficient network operations.
Link Layer Discovery Protocol (LLDP) is a tool for finding switches and other network devices. It serves on Layer 2 of the OSI model and helps identify network components in the immediate area. It is also helpful in mapping devices and analyzing network topology.
The IEEE 802.1AB document defines an extra option for CDP. This protocol helps with exchanging and controlling communication between devices.
CDP (Cisco Discovery Protocol) operates on all Cisco devices in a network. Its primary function is to discover and identify neighboring devices. Moreover, it facilitates efficient network management and troubleshooting.
All Cisco Routers and Switches devices support Netflow, a Cisco proprietary protocol. It collects information about all the devices’ traffic and network connectivity problems. Then, it sends all the traffic information using UDP to the NetFlow Collector device.
IGP is a protocol used in a company, organization, or school environment, that is, in an autonomous system (AS).
UDP (User Datagram Protocol) allows datagrams to be sent over the network without establishing a connection, as it contains sufficient address information in the header of the datagram.
Also, there is no confirmation or flow control, so the packages may be in front of each other, and it is not known whether it is correct because there is no delivery or purchase confirmation.
WEP (Wired Equivalent Privacy) is the first security standard for Wi-Fi (Wireless) networks today.
WPA is an acronym for Wi-Fi Protected Access and consists of a mechanism for controlling access to a wireless network designed with the idea of eliminating WEP’s weaknesses. They are also known as TSN (Transition Security Network).
The OSI model is a framework for standardizing telecommunications and computing systems. The International Organization for Standardization (ISO) first proposed the OSI technology in the late 1970s.
This standard provides a structured approach to the design and implementation of network systems. In addition, in this article, I will explain what the OSI model is, its layers, and how it works.
HTTP (Hyper-Text Transfer Protocol) is the protocol used in every process on the World Wide Web or WWW.
