In the real world or laboratory environment, Cisco IOS test commands are very useful and powerful commands. Learn the basic usage of this command and learn a few useful sub-commands.
This is not surprising if you have never used the Cisco IOS test command. I have met many network administrators who have never heard of
This article mainly uses an example to explain in detail how to solve the packet loss problem caused by CISCO router faults? The following article gives me a detailed answer.
Recently, some people in my department (Department A) reported that they could not access the network of the higher-level department (Department B. I use the ping command from the computer A1 (IP Address: 10.20.12.11/24) used by this p
Dynamic and robust routing is extremely important for Internet networks. Therefore, any network engineer who is first involved in this field must not only understand the concept of routing, but also be able to control it in a real environment. However, the products provided by high-end network equipment suppliers such as Cisco in the routing field are all over the world. This means that most people can only learn routes in school or laboratory environ
Many people may not have a special understanding of Cisco router configuration, so I have studied the detailed knowledge of Cisco router configuration. I will share it with you here, hoping it will be useful to you. Have you ever encountered a situation where you have modified the
packets to pass through by default. The second method modifies the default value of the router, change it to the same default as the CISCO device to block all packets.

After setting all the ACL statements on the Huawei device, use "rule deny ip source any destination any" to discard packets that do not comply with the rules.
2. Modify the default settings
Nbsp; Use "firewall defa
When the cisco router is powered on normally, perform the following steps:
1. Test the router hardware
