what s cdp

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,

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

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,

In-market backup recovery products with "mirror" technology can be backed up in real time but can not be back, there is a part of the "Mirror + snapshot" of the combination of technology products, real-time backup can be achieved, but also can do "Specify the point of data back", but can not guarantee "any point data back", nor can you guarantee the integrity of recovery data back.

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

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, w

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
