Software Requirements

The minimum software requirements for the Cisco 7401ASR router are:

•Cisco IOS Release 12.2 DX

•Cisco IOS Release 12.2(1)DD

•Cisco IOS Release 12.2(4)B

•Cisco IOS Release 12.2(9)YE

•To check the minimum software requirments 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 modules within a system are compatible, but it does provide the minimum IOS requirements for individual hardware modules or components.

Note Access to this tool is limited to users with Cisco.com login accounts.
