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.

Is the switch running cat os , if yes then try show logging buffer

Its running:

Cisco IOS Software, s72033_rp Software (s72033_rp-IPSERVICES_WAN-M), Version 12.2(33)SXH2a, RELEASE SOFTWARE (fc2)

Show log is:

show log
Syslog logging: enabled (0 messages dropped, 0 messages rate-limited, 0 flushes, 0 overruns, xml disabled, filtering disabled)
    Console logging: level debugging, 1458 messages logged, xml disabled,
                     filtering disabled
    Monitor logging: level debugging, 0 messages logged, xml disabled,
                     filtering disabled
    Buffer logging: level debugging, 1458 messages logged, xml disabled,
                    filtering disabled

        Logging to 192.168.11.44, 1430 message lines logged, xml disabled,

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".

Glen,
