Cisco routers use many methods in configuration. Using SSH instead of Telnet cisco makes it easier for us to understand the configuration of cisco routers and other knowledge points.
Replacing Telnet with cisco router configuration using SSH The Telnet protocol is a member o
centralized manner. The command syntax used to send logs to the log server is as follows:

Currently, Cisco access routers are widely used, and the features of media verification and encryption are one of the features of Cisco access routers. So I studied how to use the secure RTP media verification and encryption features, I would like to share it with you here and hope it will be useful to you. The media authentication and encryption features provided by the

the Cisco 7200 series Router, routers have multiple ports, each with several hot swappable modules. The ability to configure these modules individually via the command line is a valuable technique. At the beginning of , you might configure your router via a terminal. If the router is already configured and at least o

can run normally. However, it makes sense to rename a vro and uniquely identify it. Example:
Router (config) # hostname Router-Branch-23
In addition, you can configure a domain name on the router so that it knows which DNS domain it is in. Example:
Router-Branch-23 (config) # ip

In interception mode, the router intercepts the incoming TCP synchronization request and establishes a connection to the client on behalf of the server and, if successful, establishes a connection to the server on behalf of the client and transparently merges the two connections. During the entire connection, the router intercepts and sends packets all the time. For illegal connection req

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
