Re: IOS upgrade on 6509

Hello Mohammed,

your C6500 is currently running in Hybrid mode

sup2 with CatOS 7.2(2)

msfc2 with 12.1(8b)E11.

if you want to upgrade to a suitable native mode IOS using feature navigator

search by platform using 7600 sup2/MSFC2

for example could be

Image Name c6sup22-jsv-mz.121-27b.E4.bin

DRAM / Min Flash 128 / 32

I worry about the ATM module that I don't know if it is supported in native IOS.

By the way, is it still used and for what ?

the procedure for conversion for sup2/msfc2 is here

otherwise you can upgrade catOS up to 8.3.4 and the msfc to

Image Name c6msfc2-jsv-mz.121-27b.E4.bin

DRAM / Min Flash 128 / 16

notice the different naming convention between native and hybrid (sup22 vs. msfc2)

Hope to help

Re: IOS upgrade on 6509

Thanks Giuseppe,

ATM cards are not in use any more.

as you said

"search by platform using 7600 sup2/MSFC2"

Is this will be compatible with 6509.

Re: IOS upgrade on 6509

Hello Mohammed,

if ATM linecards are not a concern you can move to Native IOS following the procedure I have linked in my first post.

If you look at the ios image name for C7600 sup2/msfc2 native ios it is :


Now, with more modern HW and IOS images C7600 is separated from C6500 but with sup2/MSFC2 they are the same.

At the beginning moving from Hybrid mode to Native IOS made a C6500 to become a C7600.

You should be fine with it

Hope to help
