Passport switches support port mirroring for troubleshooting and network traffic analysis. Using port mirroring, you specify one destination port on which you want to see mirrored traffic and specify the source ports from which traffic is mirrored. Any packets entering or leaving the specified ports are forwarded normally and a copy of the packets is sent out the mirror port. A Passport 1000 Series switch can support mirroring on two ports. When this feature is active,
all packets received on the port(s) specified by the MirroredPortOne and/or MirroredPortTwo are copied to MirrorPort. The mirroring operation is nonintrusive.
You can also use the port mirroring feature to monitor traffic from MAC addresses where traffic with a given source MAC address is copied to the mirror port. This feature is enabled by setting the monitor field to true for a MAC address in the Forwarding window. Refer to Forwarding tab for more information.
