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 MSCs

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.

Bandwidth Oversubscription

For information on bandwidth oversubscription on the Cisco 7304 router, including information on how

SPAs and carrier cards impact the overall bandwidth of the router, see Bandwidth Information for Cisco

7304 Routers.
