Another frequently used command is show version . This command checks the booted IOS
version, system uptime, amount of RAM, flash, NVRAM, CPU type, interfaces, and the setting
of the configuration register. The way that the system was powered on (power on, reload, bug
error) can also be checked. The show hardware command displays the same information as the
show version command.

Example 3-15 displays the show version command's router output. From the output, you can
gather that this router is a MC3810 multiservice concentrator that is running IOS 12.0(7)XK1
early deployment release software. The system bootstrap software is version 12.0(1)XA4. The
router has been up for 1 day, 7 hours, and 28 minutes. The router has 32 MB of DRAM. Several
Ethernet and serial interfaces are listed. There are two voice FXS and two voice E&M
interfaces. The router has 256 KB of NVRAM and 16,384 KB of flash memory.
