Frame Size (bytes): Enter the frame size when a Layer 2, 3, or 4 BERT is selected
Frame size configuration is not available for Layer 1 BERT
Frame sizes can be from 64 bytes to 1518 bytes, in addition to jumbo frames up to 10000 bytes
BW (Transmit Bandwidth): Configure the transmit rate for the test
When traffic flow is equal to Burst, two burst bandwidths are configured with burst time
When traffic flow is equal to Ramp, starting and an ending bandwidth are configured along with the
bandwidth step size and duration
BERT Setup - Constant Traffic
Note: Frame Size Limitations
Layer 1 framed mode - Frame size configuration is not available.
Layer 1 unframed mode - Traffic profile is constant at 100% bandwidth.

13.2.1.3 Error Injection
( This description is for 10GE only)
Error injection can be performed during testing. The error type and injection rate are configured in the Error Injection
tab.
Error type: Select from Bit, CRC, IP Checksum (Layer 3, 4 only), Pause, TCP/UDP Checksum (Layer 4 only).
With Pause selected, the unit will transmit a pause frame when Error Injection icon is pressed. The Pause time
duration is configurable in units of 512 bit time. At Gigabit Ethernet speed, this is equivalent to 512 ns. For
example, if pause time is set to 1000, the pause duration will be set to 1000x512 ns.
Injection Flow: The error injection flow determines how the selected errors will be injected.
Select a single error injection or specific count.
Count: Configures the error count via a numeric keypad.
