Flow Vision features
44
• A maximum of four flow generator flows is supported per port.
Refer to “Flow parameter support” on page 1610 for more information on Flow Vision feature
limitations for flow definition parameters.
Port characteristics
Ingress Port characteristics
The source port must meet the following criteria. If it does not, the flow will be rejected.
• The port must be a 16 Gbps-capable Fibre Channel port.
• The port cannot be in the base switch.
• The port can be set to long distance or F_Port buffer.
• The port should be a simulator (SIM) port.
Egress Port characteristics
The egress port must meet the following criteria. If it does not, the flow will be rejected.
• The port must be a 8 Gbps or 16 Gbps-capable Fibre Channel port.
• The port cannot be in the base switch.
• The port can be set to long distance or F_Port buffer.
• The port should be a simulator (SIM) port.
• The port cannot be any of the following:
- Compression port
- D_Port
- Disconnected port
- Disabled port
- E_Port loopback
- Encryption port
- EX_Port
- Fast write port
- F_Port trunked
- L_Port
- M_Port (Mirror port)
SIM ports
To ensure that test flows are not unintentionally transmitted to real devices, Flow Vision requires
that you enable the source device and destination device ports in simulated (SIM port) mode
before activating the test flows, and the application checks for this setting before activating the test
flows. Setting the port to “SIM Port” sets an internal loopback on the port and creates a filter which
discards all incoming Flow Generator frames.
On a switch that has live traffic passing through E_Ports or long distance ports, Flow Generator
allows you to enable and disable SIM ports that are on the same ASIC as those active ports. Flow
Generator can also activate and deactivate the artificial traffic, allowing you to verify the impact of
the testing flow on existing traffic.
