Port Speed Monitor

We were on a job today where there was a bad crimp on an rj45 connection to a port to the router. It was only passing 100mbps rather than the full 1g.

Is there a way to monitor the ports on the router to make sure they are at full 1g? And, if they go below 1g, send an email or alert?

Thanks.

anyone?

Thanks. I will try to make a script.
