The 'detect cause' is setting up WHY you would stick a port into an
errdiabled state. You can turn the things off which annoy you.
The 'recovery' part is setting up what to do after you have been annoyed.
So by default, the switch likes to annoy you, but not do anything about it!
It's all in the perspective!

Tim,
This is what I was able to find, which confuses me a bit - what is the
difference between "errdisable detect cause" (which is enabled by
default) and "errdisable recovery" (which is disabled by default)?
<SNIP>
"ERRDISABLE DETECT CAUSE" command
---------------------------------
errdisable detect cause
Use the errdisable detect cause global configuration command to enable error
disable detection for a specific cause or all causes. Use the no form of
this command to disable the error disable detection feature.
Defaults
Detection is enabled for all causes.
"ERRDISABLE RECOVERY" command
---------------------------------
errdisable recovery
Use the errdisable recovery global configuration command to configure the
recover mechanism variables. Use the no form of this command to return to
the default setting.
Defaults
Recovery is disabled for all causes.
The default recovery interval is 300 seconds.

Unless I'm mistaken ( which happens often), all causes (there are about a
dozen or so) of err-disabled are enabled by default.
Isn't that right?
