Notes from previous studies of Cisco CCNA Courses

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 are the essence.

But Cisco's things are too expensive, the general company can not afford to use, so I have less chance to debug. In the Telecommunications Engineering Bureau, travel to the field, mobile big room is really big, equipment is also tall, but it is more impossible to let you just graduated soon casually tune, because that is in use, how many million people in the system.

So, it's basically useless.

But Cisco's philosophy is quite orthodox, like Huawei or something, a look that is picked up with others. These years, for political reasons, Cisco is increasingly marginalized in China. So Huawei has become the mainstream.

Huawei's things are easy to operate, really good, very easy to get started.
