Hi,
I am installing a FWSM module on a 6509 catalyst with a 720/MSFC3 supervisor, I am actually running 12.2(17d)SXB11a version in the supervisor and I would like to install the 3.1 software version on my FWSM (specifically the 3.1(7) release).
According to the documentation I should upgrade the IOS of the supervisor to the 12.2(18)SXF release or higher. I did some tests with the 12.2(17d)SXB11a and the FWSM module running 3.1(5) release and it seems to work fine.
Do I really need to upgrade the IOS in the supervisor?
Regards
