Cisco Networking: Show Version Command on a Router

By Edward Tetz

Issuing the show version command on a Cisco network router displays hardware unique information. Review the output of the show version command on a router and try to locate the following information. The output gives you insight into the router’s capabilities, and overall gives you practice reading the output of many Cisco commands:

  • IOS version

  • System uptime

  • Image filename

  • Type of processor

  • Amount of RAM

  • Number of ports on the switch

  • Amount of flash memory

  • Current configuration register

Here is what the show version command displays for one of my routers:
