The network structure is quite complex and there are also different protocols at each layer. Then, the CDP protocol (Cisoco Discovery Protocol) is a protocol that works on the data link layer. It is mainly used to discover and view the simple configuration information of adjacent devices. This is also a layer-2 protocol enabled by default for Cisco network devices and an important protocol for identifying the details of connected devices. It plays an

CDP (Cisco Discovery Protoco: Cisco Discovery Protocol) is a Cisco proprietary protocol used to discover adjacent contacts. All Cisco products support CDP. CDP only displays directly connected neighbor information. If another device is separated, that is, cross-device, CDP cannot be found, therefore,
CDP: Cisco Discovery Protoco
Cisco Discovery protocol is a Cisco proprietary protocol used to discover adjacent contacts. All Cisco products support CDP. Unlike the routing protocol, the next hop target port is displayed for all known networks, CDP only displays directly connected neighbor information. CDP is very help
We usually use the following command to execute, monitor, and maintain CDP information:
Cdp run command:
This command is used to enable CDP in global mode. By default, CDP is enabled in global mode. We can use the no cdp run Command to disable
When a vro or vswitch is added to the network, how does the existing network device automatically discover this "new neighbor? For Cisco, the CDP Discovery protocol works. In short, CDP discovery protocols are used to obtain information about neighboring devices. The information includes the type (vswitch or vro) of the connected device, the interface of the connected vro, the interface of the local connect

Anyone familiar with Cisco knows that the CDP protocol is a unique Discovery Protocol of Cisco. It can run on all routers and switches produced by Cisco, A router or switch running c d p can know the neighbor port and host name information directly connected to it.
You can also learn some additional information, such as the neighbor's hardware mode number and its performance. In this way, we can obtain the associated vro name, router port information,
I. The birth of CDP
CDP (continuous data protection), literally, is a continuous data protection. Continuous means continuous execution. There are many understandings of one thing. For example, running for 50 minutes every day is a type of continuous exercise. For example, if you are doing well, doing well is a continuous virtue. But running is good or doing well. Although it is continuous, there is an inte
Added support for CDP and EDP in the latest NetTool and LinkRunner, which will greatly improve the network status information provided to users during fault diagnosis. CDP is the abbreviation of Cisco Discovery Protocol; EDP is the abbreviation of Extreme Discovery Protocol. This article describes the use of CDP and EDP protocols and the information available fro

1. CDP is a Cisco proprietary protocol and can only find information about directly connected devices.2. Cisco routers send CDP updates on all interfaces by default. The default Update time is 60 s and the retention time is 180 s.3. CDP messages are encapsulated in the header and tail of the data link layer. Without any layer-3 protocol, the data link layer must

In disaster recovery backup and security storage industry, data restore is a required course, but also basic skills, but the market can fully support any point of data recovery is very few products. In fact, only real-time backup to achieve any point back, is the real CDP, and only true CDP, can reduce data loss to the minimum, or even 0 lost. And the easy to remember the preparation of excellent disaster r
communications that do not yet have an IP address, it is obvious that you can only use Mac multicast, how to route the multicast traffic received by the network card to the application, cannot rely on the protocol stack routing, because at this time the IP layer is not pass, rely on what? Rely on packet sockets!Of course, the above discussion is a bit simple, there is no IGMP and pruning and so on, in fact, for my needs, there is no need for those, with the LAN communication, above those enough

What is CDP Cloud design mode?Cloud design patterns are a set of solutions and design ideas for solving common system design problems encountered when using cloud technologies.To create CDP, we reviewed the designs created by many different cloud architectures and categorized them according to the issues that needed to be addressed, and then created a generic design pattern based on specific issues.
