Port monitoring
Port monitoring enables mirroring of ingress or egress trac of one port to another for analysis. A mirroring port (MG) or destination port,
is the port where the mirrored trac is sent for analysis. A monitored port (MD) is the source interface which is monitored for trac
analysis, also called source port.
Depending on the location of the destination interface, port monitoring is performed as follows:
• Local port mirroring — The port monitoring is performed 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 mirroring (RPM/RSPAN) — The port monitoring is performed on trac running across a remote device in the same
network. The mirrored trac is carried over the L2 network.
• Encapsulated remote port mirroring (ERPM) — The port monitoring is performed on an L3 network. The trac from the source port
is encapsulated and forwarded to the destination port in another switch.
Local port monitoring
The local port monitoring monitors trac 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.
