You can do "show logg" and look for a reason why the port was error disabled.
You can do "show errdisable detect" to see the list of events that errdisable is enabled for. By default it should be enabled for all events.
You can do "show errdisable recovery" to see if any of the errdisable events have automatic recovery enabled. By default, there should be no recovery. In other words, ports will stay down after errdisable event and you'll have to "shut" "no shut" to bring up the port. You can manually enable recovery for specific events, and you can also change the timer, after which the port is reenabled. By default that's 300 seconds (5 minutes).

Hi
what is best tunning for logg ,to see every thing in detail and the debug level

"logging buffered" controls what goes into the log. You can set the maximum message severity level and buffer size with that command. By default it should be set to level 7, which is the highest (debug) severity level. So if you enable debugging, it should go into the logging buffer
