Traffic Summary; Payload/Frame Size - Viavi Xgig User Manual

General Settings
Multiplexing options are available in Template Editor for SAS/SATA frames and primitives when
you drag them into the condition boxes in the Capture Filter and Transition editors. See the
"Template Editor" on page 146

Traffic Summary

The Traffic Summary data provides metrics for errors, OOB events, speed negotiation events,
primitives, connections, transactions, ordered sets, and frames that can be used during analysis.
Traffic Summary data is only supported for analog passthrough for 6G and 12G SAS/SATA and
8G and 16G FC blade ports. Check the
data. Note that you can also turn off Traffic Summary generation for all ports by clicking the TSV
button in TraceControl's main window menu bar so that it is not depressed. You can enable
Traffic Summary generation for all ports that support Traffic Summary data generation by clicking
the TSV button so that it is depressed.
Selecting
for SAS/SATA, and you will receive an error. However,
supported for FC. See
on Traffic Summary data in TraceView.
Important: If Traffic Summary View is enabled in TraceControl and the analyzer is stopped
manually, the link will be disrupted for a short time by an operation where TSV updates a file
on the blade. This may cause errors.

Payload/Frame Size

The Configuration Editor window shows a field to set the length of the payload/frame to capture.
This field allows you to truncate payloads/frames. Truncating payloads/frames can reduce the size
of trace when you are not interested in portions of the data.
This field displays differently depending on the analyzer hardware being used. For Fibre Channel,
the hardware can capture from 0 to 2144 bytes of payload. The first 28 bytes of header information
is always captured for Fibre Channel, so setting the
bytes of every frame. The length specified in this field has no effect on non-frame data such as
ordered sets or errors.
For Gigabit Ethernet, the hardware can capture from 4 to 16384 bytes. The Frame Size value does
not include the CRC or GE End, which are always captured with a frame.
For SAS/SATA, the hardware can capture from 4 to 16392 bytes in even multiples of four. The
Frame /Payload size value includes the SOF, but not the CRC or the EOF.
For FC, the hardware can capture in even multiples of four.
For 10Gbps Ethernet, the Payload Size is in even multiples of four.
For PCIe, the hardware can capture from 20 to 8188 in even multiples of four. The default value is
4192.
If a payload/frame contains less data than specified in field, the entire payload/frame/packet is
captured.
