Checking Hardware And Software Compatibility; Bandwidth Oversubscription - Cisco 12000 Series Hardware Installation Manual

Checking Hardware and Software Compatibility

To check the minimum software requirements of Cisco IOS software with the hardware installed on your
router, Cisco maintains the Software Advisor tool on Cisco.com. This tool does not verify whether SIPs
or SPAs within a system are compatible, but it does provide the minimum Cisco IOS requirements for
individual hardware modules or components.
