Flow Vision support
Flow Vision is supported on platforms using 8 Gbps and 16 Gbps-capable Fibre Channel platforms;
there are no platform exclusions. All ports other than those listed under
“Unsupported ports” on
page 1581 are supported. This includes ICL ports.
For details on Flow Vision feature and parameter support on switch platforms, Access Gateway
switches, and virtual fabrics, refer to
“Flow parameter support” on page 1610.
Supported ports
The following port types are supported for Flow Vision. For more information on support for a
specific feature, such as Flow Monitor, Flow Mirror, or Flow Generator, refer to appropriate sections
on those features.
• E_Ports
• F_Ports
• EX_Ports
• E_Port trunk
• F_Port trunk
• Mirror Ports (M_Ports)
Unsupported ports
The following port types are not supported for Flow Vision. Although flows can be created on
unsupported ports, activation will fail.For more information on support for a specific feature, such
as Flow Monitor, Flow Mirror, or Flow Generator, refer to appropriate sections on those features.
• Virtual FC Ports (VE_Ports and VEX_Ports)
• Mirror Ports (M_Ports)
• 1 Gigabit Ethernet ports
• FCoE ports
• LISL ports
• N_Ports
Flows
A flow is a set of Fibre Channel (FC) frames or packets that share similar traits, such as a source
port identifier or any other data that can be used to uniquely differentiate one set of related frames
or packets from another. A flow is provisioned with the following basic parameters:
• Port Parameters. These consist of the switch ingress or egress port. Only one port can be
specified. The specified port is also called the “point of interest,” or the point where you wish to
examine the data flow.
• Frame Parameters. The basic frame content provides identification of the source device,
destination device, LUN IDs, or Frame Type. You must specify at least one parameter.
• Feature Parameters. Specify one or more features, either Flow Monitor, Flow Generator, or Flow
Mirror.
