This video dives into how the CDP (Cisco Discovery Protocol) works. We will go into the actual theory behind CDP and will give live demonstrations of how this works in real time. We will also be learning how to disable CDP to give our network more security. Brief CDP summary: CDP is a Layer 2 or Data-Link layer protocol, it is enabled by default and the interfaces where CDP is enabled on will send out CDP packets on an interval timer typically every 60 seconds. These packets typically contain information such as ports the device connects onto, hostnames, version numbers of the OS and model numbers. CDP details are stored in a neighbor table that will contain all the data. Details are stored until the hold timer runs out and no new CDP packet is received which is typically every 180 seconds.

What is CDP | Cisco Discovery Protocol | Free CCNA 🤍networkkings.org The Cisco Discovery Protocol (CDP) is a proprietary Data Link Layer protocol developed by Cisco Systems. It is used to share information about other directly connected Cisco equipment, such as the operating system version and IP address. CDP can also be used for On-Demand Routing, which is a method of including routing information in CDP announcements so that dynamic routing protocols do not need to be used in simple networks. Network Kings give practice and train the engineers those who install, support and maintain these complicated missions vital networks. Facebook page : 🤍 Our blog: 🤍networkkings.org
This video covers how to configure the CDP (Cisco Discovery Protocol) and LLDP (Link Layer Discovery Protocol) protocols on Cisco devices. It also addresses some potential security concerns of using these protocols and how to disable them if needed.

How to Configure CDP and LLDP IEEE 802.1AB Link Layer Discovery Protocol (LLDP) is a neighbor discovery protocol that is used for network devices to advertise information about themselves to other devices on the network. This protocol runs over the data-link layer, which allows two systems running different network layer protocols to learn about each other.

In this video we will look at the theory behind CDP. We will see what CDP is used for as well as how CDP can be used to help draw network diagrams on the fly. CDP (Cisco Discovery protocol) is a protocol created by Cisco for Cisco that allows a device to discover all of it's neighbouring devices provided they are Cisco devices. CDP uses CDP messages to exchange information and all information is stored in a CDP table.

Presented by: 🤍blendeddigital.com.au LinkedIn: 🤍linkedin.com/company/blended-digital Facebook: 🤍facebook.com/blendeddigital Instagram: 🤍instagram.com/blended_digital/ CDP (or ‘customer data platform’) has emerged, almost overnight, as yet another must-have that every marketing team, well, must-have. But what exactly is this CDP thing that everyone’s talking about? Well, to bring you up-to-speed, the CDP market is ramping up. In 2018, market revenue climbed to $740m, up 50% from the previous year, and is estimated to exceed $1 billion in 2019. And the number of CDP platforms is picking up pace too. Salesforce recently announced that their Customer 360 platform will now be a CDP, click then Adobe jumped in to say they’re getting one too. And not to be outdone, Oracle also bragged that they’ve enlisted the help of Accenture and Capgemini to help them figure out this CDP thing. Well, the compounding challenge that marketing teams face today is that they want to deliver connected experiences to their audiences. You see, consumers now expect more than a personalised experience, instead they want every brand interaction to be a connected experience click that matches their actions and behaviours, based on in-the-moment data. For example, like immediately triggering emails based on a customers recent website engagement or an in-store purchase. And to do this, you need know exactly how they’re interacting with your channels and content. But the barrier marketers are facing is data. While the data exists, it’s very fragmented and the systems that manage this data were actually built for a different era. Customer data resides in CRM, purchase data in a point-of-sale system, web data in another system, and so on. And these number of data sources are increasing. In 2017 the median number of data sources used by marketing organisations was 10, then 12 in 2018 and 13 in 2019. Now some marketers enlist the help of their IT team to extract this data from these disparate data sources, while others import all this data into their digital marketing platform for segmentation, but these approaches are fundamentally flawed, as: Complex segmentation requires SQL modelling which calls for considerable expertise and effort, and inherently lacks flexibility. The end result is a series of large, near-time, schema-dependent datasets that can’t easily adapt without serious effort and skills. In fact, in a recent study, 81% of IT leaders say that point-to-point integration has created some of the biggest headaches they’ve seen. But a CDP is designed with exactly these problems in mind. It integrates disparate data sources by using complex matching algorithms to unify identifiers from different data sets to create a single customer view. Then it goes onto break down the barriers of traditional segmentation approaches by offering tools that enable marketers to build complex segmentation without code, then immediately surface insights (like audience size) after segmentation, showing how audiences overlap, and most importantly, provide actionable reporting, so individuals in an audience can immediately receive communication or be injected into a customer journey. And this is critical, click as in the new marketing funnel, click leads can enter at any stage, so audiences need to be highly pliable. In summary, a CDP enables data integration, orchestration, segmentation and of course that elusive single customer view — and puts all this back in the hands of marketers — right where it belongs.
How CDP Works All Cisco devices transmit CDP packets periodically (default time interval value is 60 seconds though this is adjustable). These packets advertise a time-to-live (TTL) value in seconds, which indicates the number of seconds that the packet must be retained before it can be discarded (default value is 180 seconds). CDP packets are sent with a time-to-live value that is nonzero after an interface is enabled and With a time-to-live value of zero immediately before an interface is down. This provides quick state discovery. All Cisco devices receive CDP packets, process them and cache the information in the packet. Cisco devices never forward a CDP packet. If any information changes from the last received packet, the new information is cached and the older information is discarded even if its time-to-live value has not yet expired. #software #itservices #techsupport #phishing #comptia #linux #encryption #broadband #datacenter #ccna
Todo sobre el protocolo CDP de Cisco Systems. Curso 2015-2016 Autor: JM. Calero Romero
Cisco Discovery Protocol (CDP) is a Cisco proprietary Layer 2 protocol that is used to gather information about Cisco devices which share the same data link. The device sends periodic CDP advertisements to connected devices. CDP can be used as a network discovery tool to determine the information about the neighboring devices. This information gathered from CDP can help build a logical topology of a network when documentation is missing or lacking in detail. CDP can assist in network design decisions, troubleshooting, and making changes to equipment. On Cisco devices, CDP is enabled by default. To verify the status of CDP and display information about CDP, enter the show cdp command. To enable CDP globally for all the supported interfaces on the device, enter cdp run in the global configuration mode. To enable CDP on the specific interface, enter the cdp enable command. To verify the status of CDP and display a list of neighbors, use the show cdp neighbors command in the privileged EXEC mode. The show cdp neighbors command provides helpful information about each CDP neighbor device, including device identifiers, port identifier, capabilities list, and platform. Use the show cdp interface command to display the interfaces that are CDP enabled on a device.

Here is a link to the first video in the playlist for the Complete GNS3 Labs for CCNA 200-301 Exam: 🤍 In this video we will go through the cisco discovery protocol and the cisco cdp commands. Cisco cdp clients use the cisco cdp enable command in order to enable the cisco cdp discovery tool. There are a few cisco discoveryprotocol commands. The cisco discovery protocol control protocol is used to discover directly connected neighboring devices. There are common errors like cisco discovery protocol is not available on this physical adapter. This is due to the difference between cdp vls lldp. CDP is the cisco proprietary solution while LLDP is the open standard version. CDP does work with some windows clients like Cisco Jabber.
