See Fabric OS Administrator's Guide or Fabric OS Command Reference for complete details on these commands Port mirroring With port mirroring, you can configure a switch port to mirror the traffic between a specific source and destination port. This is only supported between F_Ports. This is a useful way to troubleshoot without bringing down the host and destination links to insert an inline analyzer. 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 what available bandwidth allows will 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.

Port mirroring
With port mirroring, you can configure a switch port to mirror the traffic between a specific source
and destination port. This is only supported between F_Ports. This is a useful way to troubleshoot
without bringing down the host and destination links to insert an inline analyzer.
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 what available bandwidth allows will 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.
