Jamil,

It will either log to your buffer or wherever you're sending your logs (if you're using a syslog server). You can do a show log to see the results usually.

Try just "show log" on the router.

Hi Ibrahim,

You should have activated the logging to the buffered. In addition, you should configure the log to debugging severity level if you need to also log the debug outputs.

Finally, I would recommned to increase the buffer size to a higher value than the default (4096) in order to avoid overwriting the logs

logging buffered [buffer-size| level]

level=7 debugging

Hope that helps,

Vasilis
