Traffic Generation
A hardware-based traffic generation tool is provided to enable
network testing under heavily loaded conditions.
Hardware-based timers control the transmission of user-defined
frames into the network.
The operator may change any of the following properties of the
traffic being generated.
• Frame Length - The number of bytes in the frame, including
the FCS. This number ranges from 64 to 1518, unless long or
short frames are specified. If the Short Frames is selected, the
frame size ranges from 40 to 63. If the Long Frames is selected,
the frame size ranges from 1519 to 16000.
• Frame Rate - The rate at which the frames are transmitted by
the FrameScope Pro. Changing the Frame Rate causes the
Utilization to be recalculated.
• Utilization - The percentage of the Ethernet bandwidth
which the FrameScope Pro should fill up. This value ranges
from zero (which causes no frames to be transmitted) to 100,
(which causes the FrameScope Pro to completely load the
network connection). Changing the Utilization causes the
Frame Rate to be recalculated.
• # Frames or Continuous - Specifies the number of frames
required to be generated by the FrameScope Pro when Start
is pressed. If Continuous is selected, the FrameScope Pro
starts to generate the frames when Start is pressed and does
not stop until Stop is pressed or the Traffic Generator tool is
exited.
• Errors - Frames with errors may be generated. The error
types include CRC error, short frame, or long frame.
• Frame Type
• 802.3/802.2
• Ethernet/IP
• SNAP/IP
• Ethernet/IPX
• 802.3/IPX
• 802.2/IPX
• SNAP/IPX
• Source MAC - Choices include this FrameScope Pro MAC or
simulate multiple (10, 100, or 200) stations. The simulated
MACs use the values of 00-0C-65-01-00-XX where XX
increments from 01 to C8 (hex).
