Cisco 3020 Interconnect Systems Firmware

Duane was looking for some Cisco firmware update info:




I have a few questions around upgrading firmware of a Cisco 3020 Interconnect in a C7000 enclosure which I am hoping you may be able to assist me with? I am not familiar with these switches so any direction will be appreciated.


Customer firmware revision on their switches is currently 12.2(25)SEF1.  Current revision on is 12.2(58)SE1.


Can you go straight from 12.2(25)SEF1 to 12.2(58)SE1? Or is this a stepped upgrade? If stepped, which versions are recommended to step up to first? Is it recommended to do this via the link from the OA to the switch GUI or via a CLI connection? Is there any documentation around this?


Any information is appreciated.




From Carlos:





You need to upgrade to at least 12.2.46 or 12.2.50 to upgrade to 12.2.58.


Here is the command you need to do the upgrade:

Switch# archive download-sw /overwrite /reload tftp:[[//location]/directory]/image-name.tar



Switch# archive download-sw /overwrite tftp://




Any other comments or help for Duane when upgrading Cisco switches?
