Determining Your Software Release

To determine the version of Cisco IOS software currently running on Cisco routers, log in to the router

and enter the show version EXEC command. The following is sample output from the show version

command. The version number is indicated on the second line.

Cisco Internetwork Operating System Software

IOS (tm) 7200 Software (C7200-P-M), Version 12.0(5)S, RELEASE SOFTWARE

Additional command output lines include more information, such as processor revision numbers,

memory amounts, hardware IDs, and partition information.

Microcode Software

Table 4 lists the current microcode versions for the Cisco 7500/RSP series. This series includes the

Cisco 7000 equipped with the RSP7000 processor, the Cisco 7010 equipped with the RSP7000

processor, and the Cisco 7500 series routers. Note that microcode software images are bundled with the

system software image, with the exception of the Channel Interface Processor (CIP) microcode (all

system software images) and Versatile Interface Processor (VIP) microcode (certain system software

images). Bundling eliminates the need to store separate microcode images. When the router starts, the

system software unpacks the microcode software bundle and loads the proper software on all the

interface processor boards. VIP and VIP2 microcode is bundled into all Cisco 7500 series feature sets

listed in Table 4.

For further information about the CIP microcode, refer to the Cisco document Channel Interface

Processor Microcode Release Note and Microcode Upgrade Instructions.
