Port monitoring

Port monitoring monitors ingress or egress traffic of one port to another for analysis. A monitoring port (MG) or destination port is the port where the monitored traffic is sent for analysis. A monitored port (MD) or source port is the source interface that is monitored for traffic analysis.

The different types of port monitoring are:

• Local port monitoring—Port monitoring is done in the same switch. The switch forwards a copy of incoming and outgoing traffic from one port to another port for further analysis.

• Remote port monitoring (RPM)—Port monitoring is done on traffic running across a remote device in the same network. The L2 network carries the monitored traffic.

• Encapsulated remote port monitoring (ERPM)—Port monitoring is done on the L3 network. The traffic from the source port is encapsulated and forwards to the destination port in another switch.
