Port mirroring 9 Port mirroring captures traffic between two devices. It mirrors only the frames containing the SID/DID to the mirror port. Because of the way it handles mirroring, a single mirror port can mirror multiple mirror connections. This also means that the port cannot exceed the maximum bandwidth of the mirror port. Attempts to mirror more traffic than available bandwidth result in the port mirror throttling the SID/DID traffic so that traffic does not exceed the maximum available bandwidth. Use port mirroring to detect missing frames, which may occur with zoning issues or hold timeouts, capture protocol errors, and capture ULP traffic (SCSI/FICON). This feature cannot be used on embedded switch traffic. Port mirroring is only available using the FOS v5.2.0 or later CLI and is not available through Web Tools. For a complete list of port mirroring commands, see the Fabric OS Command Reference. To ensure proper failover in HA configurations, both the active and the standby control processors (CP) must have firmware version 5.2.0 or later installed and running. If the OS on the standby CP does not support mirroring, failing over the standby CP could cause the HA failover to fail.
