18.3.3 Discussion

There are times when it is useful to be able to clear your router's internal buffer log. For instance, while debugging a network problem, old debug messages can cause unnecessary confusion during stressful moments. This command will clear the router log:

Router#clear logging
Clear logging buffer [confirm]<enter>
Router>show logging
Syslog logging: enabled (0 messages dropped, 0 messages rate-limited, 0 flushes, 0 
overruns)
    Console logging: level debugging, 64201 messages logged
    Monitor logging: level debugging, 64820 messages logged
    Buffer logging: level debugging, 9 messages logged
    Logging Exception size (4096 bytes)
    Trap logging: level debugging, 2253 message lines logged
        Logging to 172.25.1.1, 2253 message lines logged
          
Log Buffer (4096 bytes):
Router>

This command has no effect on the other forms of logging.
