Cisco Networking: Show Version Command on a Switch
On any Cisco network component, the show version command is applicable to any of the hardware using Cisco Internetwork Operating System (IOS), including switches. The show version command displays slightly different information depending on the type of device you use it on.
Look at the output of the show version command on a switch and take note of the following information:
Type of processor
Amount of RAM
Number of ports on the switch
Amount of flash memory
The management interface that you use is the console connection. This connection is made through the Console port on the device using the blue rollover cable that came with your device. After making the connection, you use a terminal emulator program (such as PuTTY) to see what is going on with the device.
Here is a copy of what the show version command shows for a switch:
