Brocade Flow Vision Administrators Guide (Supporting Fabric OS v7.3.0) - Manual (Page 61)

• To run the test on all the ports on the local switch, set all the ports on the switch to SIM ports.
• To run the test on one slot only, set only the ports of the slot to SIM ports.
• To run the test on any other set of ports, set these specific ports to SIM ports.
The frame payload size and pattern control parameters apply to sys_gen_all_simports. The control
parameters can be the default, user-defined default, or specific to the sys_gen_all_simports flow. Refer
to
Customizing Flow Generator flows on page 67 for more details.
To start this flow, you must first enable it (specifying the ports you want used), and then you must
activate it. The following example enables SIM ports 10 through 20 and then activates the flow.
switch:admin> flow --control -simport 10-20 -enable
switch:admin> flow –-activate -feature generator sys_gen_all_simports
NOTE
Once started, sys_gen_all_simports will run until you deactivate the flow.
To stop the flow, enter flow --deactivate -feature generator sys_gen_all_simports.
To reset the flow metrics, enter flow --reset -feature generator sys_gen_all_simports. This resets
the ingress and egress counts for all the tested SIM ports.
The following restrictions apply specifically to this stress-test flow:
• You must configure the SIM ports you are going to test before activating the flow.
• There is a limit of 256 flows (64 flows at 4 flows per port) that can be generated per iteration.
• This flow bypasses all zoning, as SIM ports do not need to be zoned for the flows to be generated.
• Activating the predefined flow is mutually exclusive with all other active Flow Generator flows. If there
are any static flows or sub-flows activated on the switch, you cannot activate the predefined flow. If
the predefined flow is activated, no other Flow Generator flow can be activated.
Entering flow --show sys_gen_all_simports displays:
• The SID-DID pairs tested
• The number of complete runs where all the SID-DID pairs have been tested
• The completion percentage of the current run
• The total number of frames generated from all the ingress ports
