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.
Note
Access to this tool is limited to users with Cisco.com login accounts.
To access Software Advisor, click Login at Cisco.com, type “Software Advisor” in the SEARCH box,
and click GO . Click the link for the Software Advisor tool.
Choose a product family or enter a specific product number to search for the minimum supported
software release needed for your hardware.
