First, IntroductionThe VPP full name Vector Packet processing, is the commercial code developed by Cisco2002 years.February 11, 2016, the Linux Foundation created the Fd.io project. Cisco has joined the open source version of VPP code to the project and is now at the heart of the project.VPP runs in user space and supports a variety of ways to receive packets, often DPDK.VPP has two main functions: the framework can be extended, and the mature switchi

When we want to perform permission rating management on a Cisco router or switch, it is often necessary to assign different levels of users a command that exceeds the default settings, such as show run, which is the most basic troubleshooting command.However, the command cannot be executed when your user level is at 0-14. You can assign permissions to these users using the following command:Privilege EXEC level show Running-configWhen the configuratio

Because the study of the major is computer network technology, but in school, and did not learn how much network knowledge, so in order to be worthy of the professional, in 06, when working in the Galaxy education in hit a CCNA class, two weeks of the course, a few hours a day.The result is still not learned, because there is too much theory, too little real exercise.So I bought a book, repeatedly see, the theoretical things finally understand, the following is the final form of notes, I think a

Whether it's on a Cisco router or a network device such as a Cisco switch, the standard ACL access control list is always unable to match both the traffic source address and the destination address, nor does it meet the requirements of the "granular" control of the current network world, such as: A service function that allows access to a server, However, pinging the server is not allowed.

At present, the more popular solution flash memory fault, upgrade Flash method is to use TFTP method transmission. This article is based on the Cisco 2600 series for IT168 readers. Step one: The device will enter the Rommon state after the delete flash memory command is executed. Step two: We need to set the Rommon state to match our TFTP transfer environment. The specific orders are as follows: Rommon 3 > Set Ps1=rommon! > ip_address=172.18.16.7
