Port monitoring
Port monitoring monitors ingress or egress trac of one port to another for analysis. A monitoring port (MG) or destination port, is the port
where the monitored trac is sent for analysis. A monitored port (MD) or source port is the source interface that is monitored for trac
analysis.
The dierent 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 trac
from one port to another port for further analysis.
• Remote port monitoring (RPM) — Port monitoring is done on trac running across a remote device in the same network. The L2
network carries the monitored trac.
• Encapsulated remote port monitoring (ERPM) — Port monitoring is done on the L3 network. The trac from the source port is
encapsulated and forwards to the destination port in another switch.
Local port monitoring
For local port monitoring, the monitored source ports and monitoring destination ports are on the same device.
Congure local monitoring session
1 Verify that the intended monitoring port has no conguration other than no shutdown and no switchport.

2 Create a monitoring session in CONFIGURATION mode.

3 Enter the source and direction of the monitored trac in MONITOR-SESSION mode.

4 Enter the destination of trac in MONITOR-SESSION mode.
