Second, the boot sequence of the routerWhen the router starts, it needs to perform a series of operations, the so-called Boot sequence (boot sequence), which is designed to testHardware and load the required software. The boot sequence includes the following steps.(1) The router performs post (POST) 0 post will check the hardware to verify that all components of the device are currently operational.F

network management software, such as Cisco CiscoWorks and HP OpenView.4. Cisco configmakerConfigmaker is a free router configuration tool developed by Cisco. Configmaker configures the vro in a graphical manner, and then downloads the configuration to the vro through the network. Configmaker requires the vro to run on

confidence of a routing protocol. The lower the ad value, the higher its priority. For routing information between two different routing protocols to a destination, the router first determines which protocol to trust based on the administrative distance.

We will discuss the record and storage of Cisco router logs in the following steps. First, display the log information for the line, then save the log information to the log server, and finally send the log information to the SNMP Management Terminal. Configure the option for sending log information Log information is generally the alarm information generated by the system in

This article uses a specific example to illustrate how to configure the access to ADSL through the vro. What problems should we pay attention to during access?

I would like to introduce you to the Cisco Wireless Router setting method. Many people may not know how to optimize the Cisco wireless router settings. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. I. Basic

No one liked this, but sooner or later there would be a router crash. All that should be done now is to save the key information in the router memory so as to identify the cause of the router crash and prevent this situation from happening again. To do this, you need to configure the vro to save the core dump information stored on the vro at the time of crash. Ne

principle, using a Udpecho request instead of a ICMPECHO request to initiate an attack. While cyber security experts are focused on developing devices that block Dos attacks, they have little effect because Dos attacks exploit the weaknesses of the TCP protocol itself. Properly configured routers can effectively prevent Dos attacks. In Cisco routers, for example, the iOS software in Cisco routers has many
