flow
The following configuration considerations apply for the Flow Monitor feature:
• The ingress port and egress port can be an SIM Port, F_Port, E_Port, or EX_Port (Gen
5 or later) on the local switch. The ingress port must be a Gen 5 or later port and egress
port can be a Gen 4, Gen 5 or later port. The SIM Port must be a Gen 5 or later port.
• VE_Port, VEX_Port, FCoE ports, and GigE are not supported.
• The source device and destination device can be a host or target switch, or a wildcard
("*"). Using the wildcard ("*") enables Flow Vision to learn (discover) all flows on an
F_Port and displays statistics for each learnt flow. The learning mode is supported only
on Gen 5 or later F_Ports and trunked F_Ports.
• You can use WWN or Fibre Channel ID (FCID) for the -srcdev and -dstdev operands
when creating Flow Monitor on EX_Ports. If the Flow Monitor feature is configured on
the ingress port using FCID addressing mode, you must specify the real SID of the
source device and the proxy ID of the destination device. If the Flow Monitor feature is
configured on the egress port using FCID addressing mode, you must specify the
proxy ID of the source device and real DID of the destination device.
• Inter Fabric Link (IFL) flows can be monitored only on EX_Ports in a Fibre Channel
router (FCR).
• You can activate the Flow Monitor feature for a maximum of 64 flows per port.
• Access Gateway (AG) mode is supported
generator
Activates the Flow Generator feature for a flow. The Flow Generator is a traffic flow
diagnostics feature that generates traffic at line rate in the fabric to validate connectivity,
hardware components, and network performance. You must configure the ingress or egress
ports and the source and destination devices to be SIM ports before activating a flow using
the Flow Generator feature.
You can modify the frame size and payload pattern using the --control options after
creating the flow.
The following configuration considerations apply for the Flow Monitor feature:
• The Flow Generator feature is not supported on a base switch or ICL port.
• AG mode is not supported.
• You can activate the Flow Generator feature on four flows per port.
• The -frametype, -lun, and -bidir options are not supported with the Flow Generator
feature.
mirror
Activates the Flow Mirror feature for a flow. The Flow Mirror captures network traffic in a
flow and sends it to the switch CPU for traffic analysis. This feature mirrors only the flows
that are in active state. The logging mechanism of the frames can be modified by using the
--control -enable_wrap | -disable_wrap options.
For both switch-based system and a chassis-based system, a maximum of 256 frames per
second are mirrored. A maximum of 1280 frames are stored for switch-based systems and
5120 frames are stored for chassis-based systems.
