Displaying Event Logs
  
    The log stored in the memory buffer and the NVRAM can be displayed on the current
      session (either the console display or Telnet).
    
        Display the log using the command:
        show log
          {messages [memory-buffer | nvram]} {events {event-condition | event-component]} {severity severity {only}} {starting [date date time time
          | date date | time time]} {ending [date date time
          time | date date | time time]} {match regex} {chronological} 
        
          You can use many options to select those log entries of interest.
            You can select to display only those messages that conform to the specified:
          
            - Severity
- Starting and ending date and time
- Match expression
 
        
          The displayed messages can be formatted differently from the
format configured for the targets, and you can choose to display
the messages in order of newest to oldest or in chronological order
(oldest to newest).
