Configuring Traffic Mirroring

Characteristics of the Destination Port

Each session must have a destination port that receives a copy of the traffic from the source ports.
A destination port has these characteristics:
• A destination port must reside on the same router as the source port for local traffic mirroring. For remote
• A destination port for local mirroring can be any Ethernet physical port, EFP, and GRE tunnel interface,
• A destination port can be a trunk (main) interface or a subinterface.
• At any one time, a destination port can participate in only one traffic mirroring session. A destination
• A destination port cannot also be a source port.

Traffic Mirroring Configuration Examples

This section contains examples of how to configure traffic mirroring:

Traffic Mirroring with Physical Interfaces (Local): Example

This example shows a basic configuration for traffic mirroring with physical interfaces.

mirroring the destination is always a GRE tunnel.
but not a bundle interface. It can be a Layer 2 or Layer 3 transport interface.
port in one traffic mirroring session cannot be a destination port for a second traffic mirroring session.
In other words, no two monitor sessions can have the same destination port.
