• Data patterns—either pre-defined patterns up to 2k bytes in length, randomly
generated data or algorithmically generated data.
• DA/SA and DIP/SIP configuration is provided. By choosing between VLAN Tag,
MPLS Tag, MPLS Tunnel Tag, offset can be set through the window TxUDF. Or,
if the user defined is chosen, offset value can be configured. Various items can
be chosen individually or simultaneously through the window of MPLS or VLAN
Setup.
• Frame Identity Record (FIR)—an identity record stored at the end of the packet.
The information is very useful for determining the source of transmitted data
found in capture buffers.
• Frame Check Sequence (FCS)—the checksum for packets may be omitted,
formatted correctly or inserted with deliberate errors. Deliberate errors include
incorrect checksum, dribble errors, and alignment errors.
