Stopping 6506 CatOS Auto Reboot

davidhuynh5 · ‎03-30-2009

I have a Cat6506 running CatOS with Sup720. The supervisory modules keeps on rebooting (see attachment). How can I break out of this? Thanks in advance.

I would call the TAC if it is happening continuosly. It's either a supervisor or memory problem and would probably have to be replaced.

There is no break sequence to get into ROMMON?

Hi David,

You can go to ROMmon but I doubt if you can do anything to fix the blade.

You need to contact Cisco TAC and get the blade RMA-ed because it has totally (and utterly) failed. Based on the following error messages:
