Cisco plays a very important role in vro enterprises. It is very important to know some knowledge about common configuration commands of Cisco vrouters. So I studied how to use common configuration commands for Cisco routers. I would like to share them with you here for your reference.

Then fill in the IP, port, telnet or SSH, and finally the system version that was selected in the previous step. Login to fill in the login credentials.

Here's a script that I wrote, grabbed some information from the switch, and then saved it to a file.

The main network technology we currently use when constructing an enterprise network is generally based on exchange and virtual networks. The exchange technology changes shared media to exclusive media, greatly improving the network speed. The Virtual Network Technology breaks the restrictions of the geographical environment. without changing the physical connection of the network, the wo

This article describes in detail how to configure Cisco routers in terms of global debugging, interface debugging, and Protocol debugging. I believe this article will help you.
Global debugging
When configuring a Cisco router, the boundaries between global and interface commands are obvious. In this case, we use "Global" to identify commands that cannot be used for interface debugging or specific transmissi

Global debugging
When configuring a Cisco router, the boundaries between global and interface commands are obvious. In this case, we use "Global" to identify commands that cannot be used for interface debugging or specific transmission media types and Protocol debugging. For example, in vrouters 2500, you can use Debugging commands to analyze the Cisco Discovery Protocol (

Global debugging
When configuring a Cisco router, the bounds of global and interface commands are obvious. In this case, we use "global" to identify those commands that cannot be used for interface debugging or for specific transport media types and protocol debugging. For example, in the 2500 series router, you can use the Debug command to analyze the Cisco Discovery Protocol (

2. configuration of multiple switchesTo allow a VLAN to span multiple switches, you must configure the trunk (trunk) to connect to these switches. Cisco requires that trunk protocols such as ISL be used on such trunk links, so the command to enable trunk protocols is trunk.Use the trunk interface configur
