    Assuming you have turned on logging, type following on the cli

    show log

    If you haven't then you will need to turn it on before you can see anything by

    config term
    logging buffer debug

    Buffer logging: disabled

    Console logging is enabled, if you had connected a device to the console port of router, you can view the messages, else they are lost. Buffer is used to capture messages if you are connected through telnet.

    Look into how to use syslog - send your log files to a syslog server.  Word to the wise.
