can't view L1/L2 up/down messages on Cisco 6513 show log

I have a Cisco 6513 switch on the network.  I'm trying to view up/down messages on "show log".  The only things I see is when someone executes a write and when soneone clears an interface.  I did try playing around with console/monitor/buffer/trap logging.  I'm currenlty set to "level debugging".

I even compared the "show log" to a Cisco 3750 with no success.

Use the "logging event link-status default "   global command , you then see interface up/down events in the log.

try "logging buffered" command. Looks like buffer is not allocated in your switch..

It's already set to buffered "level debugging". this should cover severity 0 to 7 including:

emergencies        System is unusable                (severity=0)

  alerts             Immediate action needed           (severity=1)
  critical           Critical conditions               (severity=2)

  errors             Error conditions                  (severity=3)

warnings           Warning conditions                (severity=4)

notifications      Normal but significant conditions (severity=5)

  informational      Informational messages            (severity=6)
  debugging          Debugging messages                (severity=7)

Let me know if my assesment is correct.

I did enter "logging buffered", then I bounced a port.  Still don't see the up/down L1/L2 messages in "show log".
