Brief Analysis of core dump information of lingke Router

The core dump information of the lingke vro is normal for network administrators when a router suddenly fails to be used, most of which are caused by a router crash, in this case, we must first save the key information of the memory. This is what we will talk about today. I. Core Dump Information
(1) core dump refers to a complete image copy of The vro memory information. When a system crash or an irreparable error occurs on the vro, all the information in the memory is written into the memory of the server for convenience of reloading. (2) Saving a core dump information is very important for determining possible causes of system crash. The core dump information does not support personal analysis, it requires the technology of lingke to split the Board. In the case of a router crash, it is necessary to hand over the obtained information to the lingke staff. (3) Apart from core dump information, we can save or transmit a core dump file using four different methods, FTP, RCP, and TFTP. Www.2cto.com II. Flash Drive
(1) The common mode is to use FTP, whether using FTP, RCP or any other method, before creating a core dump file, make sure that the protocol works properly, in other words, before using this mode, perform a test to ensure that the system runs normally. (2) You can use the replication Router configuration to set the server that saves the core dump file to test whether the file transfer protocol runs reliably: Router # copy running-config ftp (3) because it is not restarted, You need to manually create the core dump file. In Global mode, enter the following command: Router # write core.
(4) This command is useful when the vro fails rather than crashes. Note that it will dump all the information in the memory, not just the information being used. Therefore, ensure that there is sufficient memory to accept the relevant information. In addition, I do not recommend performing this operation on the running vro. The core dump configuration is stored on each lingke router. Therefore, it is very important to identify the cause by using the core dump information that can be found once the lingke router crashes, if the core dump information is not saved, it cannot be found again once the lingke router has been restarted.
