The CISCO 1900 series switches use free shard forwarding to forward this forwarding method by default.    Check to see CDP neighbor ( not including IP)   BECN: Backward explicit congestion notification   =========================================================== ================   　　 　　B--->A ::1 Similar to 127.0.0.1 local loopback address in IPV4, for self-test 4. If the source address and destination address of the data frame are from the same port , the switch will discard the data frame by default .   Show cdp interface serial 1   　　 Show history   is cheap, but it loses the motivation to continue to struggle; if you Configuring and Verifying Redundant Interfaces R14(config-if)#dialer-group 9   End   　　 　　Header: Protocol information on the data attached to each layer of the protocol stack.

Network devices are relatively basic facilities, and only if they work properly, other applications can run correctly. Therefore, network equipment is like roads and bridges. If they are not built well, it will be impossible. Normal network communication is even more difficult to talk about. Internet technology is so complicated, so there is OSI seven-layer model technology. Because of this complexity, each manufacturer can only put eggs in a basket. Therefore, it caused some problems. Let's look at a situation. A company that produces firewalls went to another company to install the firewall. Because the firewall was added later, it needed to make some changes and settings to the original network, but the network product was made by another company. Therefore, communication is extremely inconvenient, so you need a person who is very familiar with network products. If some companies' business is very critical and urgent, this is even more true. Otherwise, the security products have not been installed, and the network of people has been paralyzed. This is a big joke. There is also a company that develops streaming media technology, to install products for people, and to configure multicast and QOS on network devices. And this is not something everyone has to do, so these companies need some network experts. Many of these companies are companies that produce firewalls, companies that develop databases, and so on. At that time, always remember to find a big company. Of course, if you are a CCIE and a master of some other aspect, this compound talent can be the technical director. If you are not going to be a technical director, you are advised to offer: 7000-12000/month.
