Chapter 13, Configuring Xgig TraceView
TraceView computes and validates the embedded CRCs and Checksums for each frame.
TraceView reports correct checksums and CRCs in the inspector window by indicating
next to the value.
TraceView reports incorrect CRCs and checksums inside the Inspector window, as well as inside
the
Errors/Warnings column
frame. However, if the hardware reported a CRC Error on a frame, TraceView will display the
correct computed value for this frame within parenthesis, for example,
the incorrect value.
The following is a list of all CRC/Checksums computed by TraceView:
•
Fibre Channel, GigE, SAS/SATA, or FCoE embedded frame CRC
(when the HW marks a CRC Error)
•
IP Checksum
•
TCP Checksum over IP and IPv6
•
UDP Checksum over IP and IPv6
•
ICMP over IP and IPv6
•
IGMP Checksum
•
OSPF Checksum
•
LSA Checksum
•
SATA Identify Device Checksum
•
SB-2 LRC
•
FCIP CRC
•
FCP CRC (both CRCs are calculated)
•
iSCSI Header and Data Digest CRCs
•
MPA ULPDU CRC
304
