The S3300 supports port mirroring. The details are as follows:

•  A maximum of four observing ports can be configured on an S3300. Packets from multiple ports can be mirrored to the same observing port. You can mirror incoming packets, outgoing packets, or both to an observing port.

•  The S3300 supports Remote Switched Port Analyzer (RSPAN). That is, the observing port and mirrored port can be located on different switches. This facilitates remote device management.

•  The S3300 supports traffic mirroring. A maximum of four observing ports can be configured on an S3300. Flows can be mirrored from multiple ports to the same observing port. Flows to be mirrored are determined by the traffic classification rule.

cool.  thanks
