Setting up the SmartBits ports to send traffic

 

Getting started: Assure PC running TRT can ping the SmartBits chassis

 

 

Step #1: Go to Card Setup

 

Step #2: Any name can be used; it will be used to identify the port

 

Step #3: Used to tell port what mode it will be used for

 

 

Step #4: BGP is enabled by default – uncheck this option

 

 

Step #5: Fiber is enabled by default on dual-media cards – assure that the proper

Media type is selected

 

NOTE: Both sides must match negotiation, speed, and duplex parameters

 

 

Step #5a: Set the IP Address, Gateway, and Subnet Mask for each port

 

 

Step #5b: Very important! Click Apply. This must be done after each config change so

that the SmartBits hardware is properly programmed

 

NOTE: At this point, verify if the DUT can ping the SmartBits ports

 

 

Step #6: Streams section is located in the Traffic folder

 

 

Step #7: Manually create streams on both ports

 

 

Step #8: Any name can be given to the streams; it will be used to track them individually

 

Step #9: A stream must be highlighted for the Edit option to be available

 

 

Step #10: Expand All will expand all the header fields

 

 

Step #11: All parameters should be configurable

 

 

Step #12: It is an option to manually insert headers – TRT will automatically update

The next header field TCP or UDP is selected

 

 

NOTE: Notice the IP addresses have been changed in each stream

 

 

Step #13: This option will use the Gateway configured in the stream and not the

Gateway configured in the Card Setup

 

Step #14: Very important! Click Apply. This must be done after each config change

so that the SmartBits hardware is properly programmed

 

 

Step #15: This icon is used to access the most common actions within the tool

 

Step #16: This will interactively start all Active streams on all ports

 

 

Verify real-time statistics and adjust the TX load

 

Step #17: Port Rates statistics are measured in frames per second

 

NOTE:  Signature frames are actual frames sent from the SmartBits ports; they do not

include other traffic received from the DUT (CDP, VTP, Spanning-tree, etc)

 

 

Step #18 & #19: The load can be adjusted per port (shared between all streams on

the same Port) or per stream

 

 

Step #20: Very important! Click Apply. This must be done after each config change

so that the SmartBits hardware is properly programmed

 

 

Enabling per-stream tracking in the Results Collection

 

Step #21: Verify the port statistics

 

Step #22: Per-stream statistics can be enabled here

 

 

Step #23: Enable charts and counters for per-stream tracking

 

 

Step #24: Very important! Click Apply. This must be done after each config change

so that the SmartBits hardware is properly programmed

 

 

Step #25:  Multiple statistics can be selected from the drop-down menu

 

 

Creating multiple streams and selectively start and stop traffic

 

Step #26: Create additional streams by right-clicking on the port; New or Duplicate

can be used but in this case, Duplicate will be selected

 

 

Step #27: Very important! Click Apply. This must be done after each config change

 

 

Step #28: Notice now that the statistics show three instead of two streams

 

 

Step #29: Interactively uncheck one of the streams and click Apply

 

 

NOTE: Notice now that the number of streams for port P1 is reduced to two

 

 

Step #30: This option will stop all traffic on all ports

 

Step #31: Please disconnect from the chassis when test is complete, or before the PC

is put in Sleep, Standby, or Hibernation mode, or when on a wireless connection and

planning to move to another location where it is possible that the PC address may change
