Log files missing interfaces transitions

[gchevalley]

For some reason I'm not seeing any log messages showing when interfaces trasitions from up to down or down to up.  Primarily this is on the 4507R's we have but I have also noticed this on mnay of the other switches and routers even though I have logging set to informational.

Try adding "logging event link-status default" to your config.

Unfortunately, that command is not available:

CORE-SW(config)#logging e?       

Hostname or A.B.C.D  exception

  Hmmm, must be because your IOS is so backleveled.  Did you try it on the interfaces ?  It should work,

Thanks, the commands were there under the interfaces.
