Do you mean that you cant issue the session 15 command to access the MSFC?

You can try accessing the console of the switch and then issuing the switch console command. This will switch to the console line on the MSFC. It may be that the msfc has booted into rommon for some reason, and trying to telnet to it via the session 15 command will not work because it is not actually fully booted.

To switch back to the console of the supervisor engine after hit ctrl + C three times.

Hope this helps

when i issue show modules, i cant see module 15.

then i reboot device and it is there and work normal for 10 days, and then problem back again.


is it possible to migrate CatOS to IOS?


It is possible to convert from Hybrid to Native IOS on the 6500's please see the below link:

However, I would suggest that this is likely to be an issue with the msfc if this is a recurring issue, and should be looked into rather than just trying to convert it. The conversion is unlikely to fix the problem is there is an underlying issue with the card.

It is also worth baring in mind that the sup has gone EOL, and it would be prudent to upgrade your hardware.

Hope this helps
