Port monitoring
Port monitoring enables monitoring of ingress or egress trac of one port to another for analysis. A monitoring port (MG) or destination
port, is the port where the monitored trac is sent for analysis. A monitored port (MD) is the source interface which is monitored for trac
analysis, also called source port.
Depending on the location of the destination interface, port monitoring is performed as follows:
• Local port monitoring — The port monitoring is performed in the same switch. The switch forwards a copy of incoming and outgoing
trac from one port to another port for further analysis.
• Remote port monitoring (RPM/RSPAN) — The port monitoring is performed on trac running across a remote device in the same
network. The monitored trac is carried over the L2 network.
• Encapsulated remote port monitoring (ERPM) — The port monitoring is performed on an L3 network. The trac from the source
port is encapsulated and forwarded to the destination port in another switch.
Local port monitoring
The local port monitoring monitors trac from one or more ports from the switch to one or more ports on the same switch. For local port
monitoring, the monitored source and monitoring destination ports are on the same device.
Congure local monitoring session
1 Verify that the intended monitoring port has no conguration other than no shutdown and no switchport.
