log information is divided into eight levels. the urgency of information is ranked in terms of importance from high to low, Emergencies (very urgent) is of the highest importance, and Debugging (commissioning) The least important . 2 , configuration Log log information can be output to Log Buffer (log buffer), ASDM and log servers. Before configuring the log, you typically need to configure the time zone and times, as follows: 1 ) Configure the time zone: The command is as follows:
