we have a 6509 core switch in our datacenter.
this 6509 includes two supII.
these two SUP II has same problem
their RP will crash but their SP work fine.
when I boot the swtich from the my disk (IOS Software) after few seconds the system software forces to crash and reloaded!
but when voot the switch with CATOS it works without any crash!
any idea please?
