4.3 OVERVIEW: PORT MIRRORING
The Matrix E1 allows you to mirror the traffic being switched on one or more ports for the purposes
of network traffic analysis and connection assurance. When port mirroring is enabled, one port
becomes a monitor port for other ports within the device. When configuring port mirroring on this
device, note that
• A given source port may only be mirrored to one target port. However, multiple source ports
may be mirrored to the same target port.
• Only one port per port grouping can be designated as a source port. For more information on port
grouping designations, refer to Section 4.4.2.
• A maximum of 12 source/target port pairs may be configured.
• Traffic mirrored includes both received and transmitted packets.
• Unknown protocol packets and broadcast packets can be forwarded out the monitor port when
mirroring is enabled.
For details on how to specify port designation in the CLI syntax, refer to Section 4.1.2.
