It is this configuration that is loaded into memory when the device is first booted. This command is the same as the above show running-configuration command except this will output the configuration that is stored in NVRAM. More system:running-config Command: show startup-configuration To see the whole output at once use the command terminal length 0 before entering the show running-config command.Īny passwords or shared keys are usually encrypted and therefore not visible in the output, however it is possible to show the plain text output of shared keys for RADIUS servers or VPN connections in the running-configuration by using the command Pressing the enter key displays one line at a time and pressing the space bar displays one whole page at a time.

In this article I have created the following Cisco Show Commands Cheat Sheet with brief description of the most important and most useful commands you will need as a Cisco Network Professional (both for IOS Routers and Switches). They are crucial when troubleshooting problems in the network or for displaying useful and critical information from the router or switch. There are commands that configure the device to perform a certain function and also there are commands that extract information from the device and the whole network in general.Ĭisco “ show commands” belong to the second category above.
There are a few different categories of commands on Cisco devices. If you are a networking professional that is operating and supporting Cisco devices and networks, then learning some important “ show commands” is essential.
