the technical assistance center and send the obtained information to trained staff. Remember that the core dump information must be saved when the router crashes. After the vro is restarted, such core dump information does not exist. Important troubleshooting commands used when a router crashes Before learning how to configure the core dump information, let's take a look at some important commands for trou

systems of Cisco router IOS, which may expose sensitive information. This vulnerability allows a low-level user (for example, a user who does not know the 'enable' password) to use the system to view some information, in theory, this information should be visible only to users who know the 'enable' password. This information includes the access control list and other content. Generally, after logging on to

Cisco SDM is a good tool for vro security configuration. It features easy to learn and allows users to easily complete vro settings. Cisco SDM is based on Cisco IOS®An intuitive Web device management tool developed by Software routers. It simplifies router security configurations through smart wizard, allowing customer

If a Cisco Wireless Router is improperly configured, problems such as disconnection and disconnection may occur. It is very important for us to have a deep understanding of the details in Cisco wireless router configuration. Next we will introduce the relevant knowledge in detail. As we all know, wireless signals are t

It is very important to know some knowledge about backing up the cisco router configuration file to make our vro more secure. Here we will give you a detailed introduction to this issue in several steps. The COPY command is often used during vro configuration. Next we will introduce how to use the COPY command to back

There are many knowledge about Cisco routers. Here we mainly analyze the specific methods for Cisco router configuration.

kind of configuration can best meet security needs without compromising network performance? This article describes the following parts: Cisco Router Security Configuration. Password Management A vro uses a password to prevent unauthorized access to the vro and is a part of the security of the vro. The best way to handle these passwords is to save them on the TA

Users using Cisco routing, many of them do not pay much attention to doing Cisco router configuration work, in fact this is a very important part, especially for our network security. There are several ways to do Cisco router configuration. The configuration can be done by t
