i am the 51CTO lecturer Kanhaijiang, at the Institute 11.11( People's IT Learning Festival) Come on the occasion, and everyone to share my CCNA customs clearance experience. The text is coming ~ ~ ~in writing this title, I seem to have returned to the original to learn Cisco Qizaotanhei, but a fun time. Obviously, I am definitely not a network genius, no extraordinary talent, even at that time even a computer belonging to their own elusive, so in the

From today on we review together to learn the debugging of routers and switches. Based on the CCNA tutorial, we practice a few small commands every day, and make up a little, and finally become an amplifier.Enable: Enter privileged mode and the command prompt becomes hostname# after runConfigure Terminal: Enter the global mode command prompt to change to hostname (config) #Hostname: Naming the deviceExit qu

isolated from the rest of the network, thereby reducing the likelihood of disclosing confidential information. Messages in different VLANs are isolated from each other during transmission, and different broadcast domains want to communicate between them and need to pass through one or more routers. VLANs can divide a second layer of planar networks into multiple logical workgroups (broadcast domains) to reduce unnecessary traffic on the network and improve performance. Experimental topological

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 fo

CCNA Study Notes (ii)--Initial knowledge of Cisco devicesIn the previous chapter we recognized the fundamentals of networking, and now we are formally exposed to Cisco devices.1, first we first understand the main components of a Cisco device:ROM (read-only memory): mainly save the post software, save the router boot boot program.RAM (random memory): loss of data, can store configuration files. >>> equivalent to PC memoryNVRAM (non-volatile memory): p
