3.14.5 Port Monitoring
The user can configure port mirroring on this page. This function can be used by the administrator to
debug network problems. The selected traffic can be mirrored or copied on a destination port where
a network analyzer can be attached to analyze the network traffic.
As will be explained below, the traffic to be copied to the mirror port is selected as follows:
•
All frames received on a given port (also known as ingress or source mirroring)
•
All frames transmitted on a given port (also known as egress or destination mirroring)
Remote mirroring (RMirror) is an additional function available on the switch to extend the destination
port to another switch of the network. So, the administrator can analyze the network traffic on several
different switches.
