  Viewing Cable Diagnostics

Port mirroring monitors and mirrors network traffic by forwarding  
copies of incoming and outgoing packets from one port to a  
monitoring port. Port mirroring can be used as a diagnostic tool as 
 well as a debugging feature. Port mirroring also enables switch  
performance monitoring.

network administrators can configure port mirroring by selecting a 
specific port from which to copy all packets, and other ports to which 
the packets copied.
