Hello all,
We have an ISR-4331 that is running IOS XE 3.16.09.5 and need to get it upgraded. I see that both 17.6.3 and 17.3.5 are recommended releases.
I did see that a ROMMON update is required. Besides that, would we be able to upgrade directly to either of the recommended releases? I didn't find any prerequisite versions, or upgrade paths, mentioned in the release notes.
Thanks

Yes I've upgraded with this 'jump' before from 3.x to 17.x i believe it is because of the architecture of the packages- as you righty stated need to make sure ROMMON is performed before as a pre-req as it's commonly outdated.

Hi All,
We have a new router to be deploy at site - the router model is Cisco ISR 4431 and firmware release is version 17.3.5
So I would like whether the 17.3.5 is the latest version ? or do we need to upgrade to 17.6.x release?
Your advise and recommendation is highly appreciated.
Thanks

Which one do i need to download ? the first one or the other with (No Payload Encryption) ?
05-24-2023 01:58 AM
Download the first one because it supports SSH.

How do I check the md5sum verification for this firmware version file?
05-25-2023 12:37 AM
There is no need to check the MD5 checksum because if the MD5 do not match, the Install Mode procedure will stop without rebooting the router.
