Monitoring traffic

There is packet loss in between my network to my upstream provider. My WAN link is connected with fiber optic cable (using mux.) I think this is happening due to broadcast - how can I do some diagnostics on Cisco switch or router (by which command)?
If you are going to monitor traffic at one of your Cisco switches you'll need to span a port.

First - Telnet to the switch or use a console cable for direct connection

Second ? If it is a Cisco Catalyst switch choose the Menu option.

Third ? Select M for monitoring. You'll need to define the monitoring port and the port connected to your router.

Finally ? Start your analyzer. If you don't have one you may want to check out Ethereal. It's free!
