Port Mirror 

A Port Mirror is a mechanism which provides a method to observe traffic that is 
flowing on one port from another port. This can be very useful in a debug situation. 

If there is no access to a connection, a mirror‐to port can be created that can be 
attached to an external analyzer. Any port, except the mirror‐to port itself, can be 
designated as the mirror‐from port for traffic occurring on the p

ort to be observed. 

The switch supports one mirror‐to port at a time. The mirror‐from ports can be a list 

of ports with ingress and egress as configurable options.
